ASPEN/PITKIN COUNTY FIREPLACE AND WOODSTOVE REGULATIONS
In order to keep our air as clean as possible, the elected officials of Aspen and Pitkin County have passed ordinances to regulate the
number of fireplaces and woodstoves that can be installed in any building. Building permit applicants must file a
fireplace/woodstove registration with the City of Aspen Building Department or the Pitkin County Building Department before the
building permit is issued.
Pitkin County is separated into 2 areas. One is the non attainment area, which includes the City of Aspen and the Metropolitan
areas of the county, i.e. Mountain Valley, Red Mountain, Difficult Ca mpground, T Lazy 7 Ranch, and part of Starwood. The other
is the attainment area which includes the less densely populated parts of the county, i.e. Brush Creek Village, Holland Hills and
Old Snowmass.
Decorative gas appliance: A device utilizing natural gas as a fuel gas designed to appear as a real fireplace with a 4 to 5 inch Class
B vent or direct vent, fixed glass door and a firebox no deeper than 24 inches.
Certified Woodstove: Colorado Phase III certified woodstove or a Phase II EPA certified woodstove.
Gas log fireplace: Meet all codes for burning wood but are used with gas logs. They are not allowed in bedrooms.
Aspen and Metropolitan Areas of Pitkin County in the non attainment area
New buildings in the non attainment area may have either 2 gas log fireplace or 2 certified woodstoves or 1 each. They may also
have an unlimited number of decorative gas appliances. Wood burning fireplaces cannot be installed, nor may coal be used as fuel.
Remodeling or an addition to an existing home in the non attainment area
· If the building has 2 or more fireplaces, gas log fireplaces or woodstoves, they only devices you can add are decorative gas
appliances.
· If the building has 1 fireplace, gas log fireplace or woodstove, you may add 1 gas log fireplace and an unlimited number of
decorative gas appliances.
· If a building has more than 2 fireplaces, gas log fireplaces; if one is affected by the remodel it must be removed.
· If a building has only 1 or 2 fireplaces, woodstoves or gas log fireplaces, please keep in mind:
o If you alter the firebox of a fireplace, it must be converted to gas logs or removed.
o If a woodstove is moved, it must be removed or replaced with a department certified woodstove.
Attainment Area in Pitkin County
New residential buildings in this area may have one wood burning fireplace and one gas log or certified woodstove. If there is no

Where the flooring material at the opening of the fireplace is
combustible, it is required that the hearth extension be covered
with a non-combustible material. The extension should be set
flush against the front of the fireplace front and measure 20”
minimum at the front (1’-8” min) and 12” minimum (1’-0” min)
beyond the sides of the fireplace opening as shown in Figures
10 and 12.
If a raised hearth extension is being installed, it must be
constructed of non-combustible material and any material
under the structure must also be non-combustible.
If using a raised hearth or metal base plate, note that a
combustible wood header must be no closer than 2” to the top
of the dome (see Figure 13).
Attention: You will note that there will be a gap between the fireplace front and the extension of the non-combustible hearth
material. Be certain that you seal this with non-combustible
material.1’-8”MIN2” MIN

Product Overview
Introduction
We extend a warm welcome from all of us at Masonry
Fireplace Industries, LLC. (MFI), proud manufacturers of
Mason-Lite Fireplaces. Thank you for Choosing MFI.
You may have thought long and hard before you chose the
fireplace which would grace your home. Rest assured that
every component of the Fireplace has been tested to ensure
long-term durability.
Product Overview
Mason-Lite Fireplaces are designed as factory-built blocks
to be assembled on-site. These fireplaces may be installed
on either combustible or non-combustible floors. In order for
the fireplace to be installed on a combustible floor though, it
is necessary that the fireplace be supported on a platform or
sub-floor that is non-combustible.
The Four Components of the Mason-Lite Fireplace:
• Combustible or Non-Combustible Floor
• Non-Combustible Raised Platform
• MASON-LITE Firebox and Smoke Dome
• UL103 class A listed chimney system required.
Important: Follow the chimney pipe manufacturer’s
instructions on the installation of their specific flue system.
Careful step-by-step instructions for each phase of
the installation procedure will be given for the Mason-Lite
conventional radiant heat fireplaces. Those instructions
generally fall into the following categories:
• Spacing and clearance as it relates to combustible
materials.
• Familiarity of installation for all components.
• The strength of the floor on which it rests.
• Chimney system measurements.
• Choice of materials and craftsmanship in fireplace and
hearth finishing.

Note that each of these topics will be covered in detail and that
the installer is expected to understand each phase completely
before going on to subsequent instructions.
Attention: Be advised that all the illustrations in this manual
are for general reference only. Do not scale drawings. Actual
design elements will vary from case to case. Pay attention to
specified minimum clearances to combustibles.
Testing and listing for these Mason-Lite Fireplaces has been
undertaken by PFS, Inc.
Attention: You may need a residential building permit to install
a Mason-Lite Fireplace. Consult local jurisdictions before you
get started!
If asked, advise the local authorities that the Mason-Lite
Fireplace is designed for installation per the National Fire
Protection Association Standard for Chimneys, Fireplaces,
Vents and Solid Fuel-Burning Appliances (NFPA211).
When choosing the location of your Mason-Lite Fireplace, keep in mind you must maintain 2” (two inches) minimum clearance from left, right and rear of Fireplace to surrounding structure. Also, when choosing a location, consider outside air requirements to determine if it will be on the left or right side of the Fireplace. In the case of an island installation, outside
air accessibility may be obtained through sub flooring. See
section on Installing Outside Air on page 28.

Understanding Clearance to Combustibles
There is a build-up of a considerable amount of radiant heat on the outer surfaces of the Mason-Lite Fireplace. It’s critical
that proper clearances to combustibles be maintained so that
this radiant heat is maintained to safe limits.
Combustible Floor Clearances
These Mason-Lite Fireplaces have been designed with clearance to combustible floors as indicated in Page 18. Cover any part of the combustible floor system left exposed with 1” (one inch) thick ceramic fiber insulation rated up to 2,100° F.
Attention: It is critical to abide by the clearances listed in this
manual for all components specified as it allows for movement
of hot air from the fireplace into interior areas of the chimney
chase. Also, be certain that the chimney system be installed
as stated below. Prior to starting the installation, check with local, regional or state codes for any restrictions or required permits regarding your fireplace installation.
Mason-Lite Fireplace & Chimney System
1) The Mason-Lite is designed to be installed with a listed
UL103 - Class A, Metal Chimney System.
2) This Mason-Lite fireplace is intended as a supplemental heat source only. It is not intended as a primary heat source.
3) It is the responsibility of the contractor installer (not the manufacturer) to ensure that adequate combustion air is provided for proper function of this fireplace. Fireplaces take up a large volume of replacement air from outside the house and if the house is of airtight construction, smoke spillage may occur if proper draft is not achieved.
4) There are many conditions beyond the manufacturer’s control regarding improper fireplace operation. The manufacturer cannot ensure “smoke free” operation, nor can the manufacturer take on the responsibility for problems with surrounding construction; chimneys that have not been built at the correct heights; system drafts caused by faulty mechanical systems; adverse weather conditions or any other environmental situations over which the manufacturer has no control.
5) Inspect all fireplace & chimney components for evidence of damage prior to starting installation. Consult your local distributor for replacement parts if necessary.
6) Under no circumstances should you make any adjustments or modifications to the chimney system during the installation procedure. If you do, you are not only liable for negating the warranty, but you could very well cause a serious malfunction of the fireplace. You must follow these chimney instructions.
7) Caution is urged if it is decided to add insulation material to any part of the Mason-Lite Fireplace or Chimney system, be certain that the insulation material is kept at least 2” (two inches) away from any part of the system. When using insulation or vapor barrier materials, cover with a layer of plywood, particle board or gypsum board to maintain the specified 2” (two inch) clearance.
8) Air spaces around firebox must remain open. DO NOT fill these open spaces with insulation or packing material of any kind.
Chimney System Heights
When installed, the maximum overall height of the chimney
system from bottom of fireplace to the top/termination chimney
is 40 feet. The minimum installed height of the completed
Chimney System is 14 feet with a straight flue stack, 17 feet if
the chimney includes one or two offset sections.

Supporting Floor Systems
It is the ultimate responsibility of the installer to ensure that proper concrete slab supports are used.
WARNING to the licensed design professional and/or building
contractor: It is your responsibility to be certain that the Mason-Lite can be properly supported by the combustible floor system on which the fireplace will rest.
For fireplace support foundations installed on concrete refer to Appendix I and II (pages 31 & 32) for specific instructions.
Rebar locations Lay-out the position of the fireplace and drill holes where the rebar will be located. Secure the #3 rebar 4 inches into the concrete foundation with ITW Epoxy or Simpson Epoxy. Follow manufacturer’s instructions for installation of rebar into slab.
Wood Floor
Anchorage of fireplace to wood floor construction is required. Refer to Figure 21 for anchorage dimensions. Four anchors are required to attach to the sub-flooring framing.
Crawl Space or Upper Floor:
For installation of firebox over combustible crawl spaces or upper floors, anchorage of the firebox is required. Illustrations of examples of possible anchorage methods are shown in Figures 18 thru 20 depending upon the type of floor framing. Final method of anchorage is to be determined by licensed design professional.
For conventional framing, where the floor joists are parallel with the sides of the firebox, the addition of floor joists to align with the anchor brackets allows the brackets to be directly connected to the floor joists. Note that additional floor joists may be required to support
the weight of the firebox and chimney. Where the floor joists
run parallel to the front of the firebox, anchorage can be
accomplished in like manner as shown in Figure 18 using blocking between the floor joist.
For floors supported by I-Joists, the method of anchorage is illustrated in Figures 19 and 20. Figure 23 illustrates the general arrangement of anchorage to floor framing.
It is important to take into consideration that the load for the Mason-Lite Fireplace must be considered as additional dead load that will have to be supported by the floor framing.
Additional floor joists or I-joists may be required as determined
by the licensed design professional.
The dead weights for the fireplace are noted in Table I. It is the task and responsibility of the general contractor/installer to see that the proper reinforcement for weight loads are made by a licensed design professional prior to the fireplace installation.
As stated above, it is desirable to place additional framing for alignment of anchor rods. Refer to Figure 21 for anchor rod locations.
Attach the firebox side wall anchors to steel support frame by inserting all-thread rods through holes on the bottom flange on the steel support frame as shown in Figure 24 and 25. Secure with two Ø 2” o.d. x Ø 9/16” i.d. x 0.10” Washers and two 1/2”-13 UNC Nuts.

What You Will Need
You will find that the MASON-LITE Fireplace is designed to be completely assembled on-site, consisting of interlocking precast parts. You will need a thin-set type mortar for bonding. The parts of the fireplace are made of Mason-Lite’s incredibly strong blend of specialty cement and a light weight aggregate.
IMPORTANT! When applying mortar, it is imperative that the
concrete blocks be maintained moist (not soaking) so they don’t
absorb the water out of the mortar and cause adhesion to fail. Frequently run a damp sponge to the parts before mortar is applied!
The installation of an anchor plate/damper is required but not supplied. You may purchase it from any chimney manufacturer or MFI. Also, an optional combustion air inlet MFP4-AK can be obtained from MFI.
Refractory Firebrick Liners also need to be installed. These
should be a minimum of 1-1/8” (one and one-eight inches) thick.
The liner will be applied within the walls and hearth area of the firebox. These are available from MFI. See page 27.
Tools needed for installations:
• One 4’ level
• Roto-hammer with ½” drill bit (needed for concrete slab install only)
• Drill motor with mixer blade (to mix Mason-Lite Mortar)
• Two empty 5 gallon buckets (to mix Mason-Lite Mortar)
• One wheelbarrow and shovel to mix concrete.
• Grout bag
• Triangular masonry trowel
• Rubber hammer
• Sponge and water bucket to wipe down and moisten parts prior to applying mortar.

• Four or more fasteners to attach metal base to floor joists
• Mason-Lite Mortar (one 50 lb. bag for MFP-33/39/44/49 or two 50 lb. bags for MFP-63)
• Three (3) - 90 lb. bags of ready mix concrete with 1/4” or smaller aggregate.
Field Assembly Procedures
a) Mixing the MASON-LITE mortar – The mortar comes
premixed and should be dry. Be sure to use clean water and work it up into a mixture that is pasty but not lumpy. If it’s too thin and the surfaces don’t stay moist, the components will not adhere. Load the mixture into a standard grout bag.
b) Apply about ½” (one-half inch) thread of mortar. The mortar bead should be approximately ½” (one-half inch) away from
all edges. The mortar has a considerable amount of holding
power so do not overload the components with too much
mortar. Keep the components moist at all times!
c) Some mortar will “ooze out” when placing components together, this is normal. Wipe excess away with a trowel. Do not cover component surfaces completely with mortar. Do not apply the mortar in thick bands even if the component you are working with is larger than the rest. You will want to
apply “stripes” of mortar in these situations.
d) Make sure components are level. It’s extremely important that you pay careful attention to how you are assembling the Mason-Lite Fireplace since every component builds on the next. If you have to make any kind of an adjustment, do not try to do it “by loading an opening” with mortar, this will only result in a fireplace that will not be plumb or level. Use wood shims instead. You will find these small wood shims supplied with the Mason-Lite Fireplace and
you can nudge them in between openings to achieve the
precision you need in making component adjustments. Once you have removed any shims, you will want to cover any gaps that may have resulted with the mortar. 10/30/2018

Assembly Instructions
1. Place the Mason-Lite Fireplace hearth base on top of your non-combustible floor or metal base. For concrete slabs, supporting floor needs to be rated at ASTM 90.
2. a) Combustible Floor Installations: Mix up a batch of
mortar and adhere hearth slabs to the cement board (see Figure 25). All-thread rods should stick up through the holes on the hearth slabs. b) Non-combustible Floor Installations: Draw an outline of the hearth area based on the dimensions shown in pages 8 and 9. Position Hearth slabs and mark rebar center locations. Drill 4 inches into concrete slab and secure the 8 pieces of 12 inch rebar with epoxy.
3. Mix a batch of mortar and prepare Right Side Hearth bottom surface to be bonded as shown in Figure 27.
4. Align Right Side Hearth to the outline created. The overall width should allow for an approximate gap of 1/8” between slabs for the additional mortar to unite the remaining slab. Check for surface flatness, level if necessary.
5. Apply mortar to the remaining Hearth except this time apply beading on surface to be facing floor as shown in Figure 28.
6. Before installing side walls, confirm placement of outside combustion air access (if required), this can be installed either side depending on which side is accessible to outside combustion air (all diagrams in this manual show the combustion air inlet hole on the right side). Prepare side wall and rear wall mating surfaces with the prepared mortar and begin assembly.
7. Keep the assembly of the next sections of the firebox side
walls moving up, keeping components moist, mixing mortar
as you need it and threading the mortar appropriately as you stack each section, one onto the next. Constantly check for squareness and levelness while building each course of block. As you complete each section, make certain that you adhere the mortar at each and every joint.

8. MFP-33 ONLY: After the second row of firebox is complete,
install Smoke Shelf and remaining side walls (Figure 31).
Mix approx. 2 cu. ft. of Ready-Mix Concrete. Insert 28”
rebar vertically through the cells, into the holes in the hearth, adjacent to the rebar and/or all-thread sticking up from the hearth. Fill all cells with Ready-Mix Concrete mix.
9. Set the Lintel and Lower Rear Dome in place as shown in Figures 32. Check that all is level. If you need to make adjustments, use shims. Place one or more of these shims between the lowest wall component and the top surface of the base plate. Once you are satisfied with the degree of levelness, you can address any gap that may have occurred with an appropriate amount of mortar. Note: Although you are cautioned to use MASON-LITE mortar sparingly because it does have such holding power,
you should look over the firebox assembly at the end and fill
in any gaps, especially joint connections, with the mortar.
Important: Adjustments can only be made while the mortar is still wet when correcting for squareness and leveling.
10. Assemble Lower Dome Sides as shown in Figure 32. The beveled face lines up with the inward angles of the lintel sides. Top surfaces should be level.
11. As you are connecting each MASON-LITE component, be
certain you are following the instructions given previously
for using MASON-LITE mortar. Stop to look at the smoke
dome side, front and rear walls to see that they are aligning correctly and that the surfaces are smooth and uniform. Make sure connections are covered with an adequate amount of mortar. Remember that you have the option of using shims but they must be removed and any holes filled. Make any adjustments to the fireplace alignment before continuing to the next step.
12. Assemble Upper Dome (MFP33-10) and Dome Sides (MFP33-8) as shown in Figure 33. Check your assembly
here. If things are proceeding as they should be, the
finished top surface should be flat and level.
13. Finally, set the Dome Top into position. Be sure that it is flush in every direction as you place it on the crest of the smoke dome wall assembly. After this is done, proceed to section on “Installing Damper and Chimney System” on page 26.
Note: The chimney hole on the Dome Top is not centered from front to back - it should be offset closest to the rear of the fireplace (see Figure 33).

14. MFP-39/44/49: After the third row of firebox is complete, place #3 rebar (36” long) vertically through the cells until they reach bottom. Position them adjacent to the rebar or all-thread sticking up from the hearth.Figure 34.
15. Install Downdraft Diverter and final row of Side Walls
(Fig.35). All components must be level. Mix approx. 2
cu. ft. of Ready-Mix Concrete. Insert 28” rebar vertically
through the cells, into the holes in the hearth, adjacent to the rebar and/or all-thread sticking up from the hearth. Fill all cells with Ready-Mix Concrete mix.
16. Set the Lintel, T-Bar, Lintel Front and Lower Rear
Dome as shown in Figure 36. Check that all is level. If adjustments are needed, use shims and fill gaps with an appropriate amount of mortar. Note: Although you are cautioned to use MASON-LITE mortar sparingly because it does have such holding power, you should look over the firebox assembly at the end and fill in any gaps, especially joint connections, with the mortar. Important: Adjustments can only be made while the mortar is still wet when correcting for squareness and leveling.
17. Assemble Lower Dome Sides as shown in Figure 37. The beveled face lines up with the inward angles of the lintel sides. Resulting top surfaces should be level.
18. Verify that the Smoke Dome side, front and rear walls are aligning correctly and that mating surfaces are smooth and uniform. Make sure connections are covered with an adequate amount of mortar. Remember that you have the option of using shims but they must be removed and any holes filled. Make any adjustments to the fireplace alignment before continuing to the next step.
19. Assemble Upper Dome and Dome Sides as shown in Figure 38. The top surfaces of all dome parts should be
flat and level.
20. Finally, set the Dome Top into position. Be sure that it is flush in every direction as you place it on the crest of the smoke dome wall assembly.
Note: The chimney hole on the Dome Top is not centered from front to back - it should be offset closest to the rear of the fireplace. The front of the dome is indicated by a marker (see Figure 39).

MFP-63 Assembly Instructions:
21. Place the Mason-Lite Fireplace hearth base on top of your non-combustible floor or metal base. For concrete slabs, supporting floor needs to be rated at ASTM 90.
22. a) Combustible Floor Installations: Mix a batch
of mortar and adhere hearth slabs to the cement board (see Figure 24, Pg.18). All-thread rods should stick up through the holes on the hearth slabs. b) Non-combustible Floor Installations: Draw an outline footprint 67” x 28” for the MFP-63 footprint and mark the centers for the rebar locations using the hearth slabs as templates. Drill holes for rebar 4 inches into the concrete slab and secure the 10 pieces of 12” long rebar with epoxy.
23. Mix a batch of mortar and prepare bottom surface of Right Side Hearth to be bonded (Figure 41), then lower the piece into place on the outline created before. Align lower Right Side Hearth on the outline created. The 67” width
dimension allows for an approximate gap of 1/8” between
slabs for the additional mortar to unite the remaining
slabs. Continue process for remaining hearth sections while moistening and adding mortar between joints at slab ends.
24. Apply mortar in like manner to the Center Hearth and
place next to the Right Side Hearth. Check that surface is
LEVEL and use shims if necessary.
25. Apply mortar to the remaining Hearth except this time apply beading on surface to be facing floor as shown in Figure 42.
26. Before installing side walls, confirm placement of outside
combustion air access (if required), this can be installed
either side depending on which side is accessible to
outside combustion air (all diagrams in this manual show the combustion air inlet hole on the right side).
27. Prepare side wall mating surfaces with the prepared mortar as shown in Figure 43.
28. Keep the assembly of the next sections of the firebox side walls moving up (Figure 44), keeping components moist, mixing mortar as you need it and threading the mortar appropriately as you stack each section, one onto the next. Constantly check for squareness and levelness while building each course of block. As you complete each section, make certain that you adhere the mortar at every joint.

29. Rear walls are staggered on every row as shown in Figures 45 and 46.
30. After the third row of firebox is complete, install Downdraft Diverter sections (MFP63-4) as shown in Figure 47.
31. After the last side walls are installed, place #3 rebar (10 each, 36 inch long) vertically through the cells, into the holes in the hearth, adjacent to the rebar and/or all-thread sticking up from the hearth and fill all cells with Ready-Mix
concrete mix.
32. Set the Lintel and Lower Rear Dome in place as shown in Figure 48. Check that all is level. If you need to make adjustments, use shims between the lowest wall component and the top surface of the base plate. Once leveled, fill any resulting gaps with mortar. Important: Adjustments can only be made while the mortar
is still wet when correcting for squareness and leveling.
33. Assemble Dome Sides (MFP63-7) as shown in Figure 49. The beveled face lines up with the inward angles
of the lintel sides. Top surfaces should be level.
34. Position Middle Domes (MFP63-10) so that outer faces are flush to the lower dome as shown in Figure 50.
35. Carefully install Dome Middle Sides (MFP63-8) as shown in Figure 50.

Attention: Clearance to combustible construction cannot be reduced during course of construction. For the safe operation of the finished fireplace, these clearances must be followed when building the framework for the chimney system.
Note that the most important aspect of the installation is maintaining the minimum required clearances to combustible materials according to the chimney pipe manufacturer’s recommendations, otherwise a potential fire hazard may occur.
Warning: do not interchange chimney manufacturer’s parts with any other parts except those specifically required by the chimney manufacturer’s recommendations otherwise a potential hazardous condition may be created.
Attention: When choosing a Chimney System it must meet the following requirements:
Designed for installation in accordance with the National Fire Protection Standard and UL 103.
Meets the requirements of NFPA 211.
Designed in accordance with ICC Codes.
Assuming you have sections of vertical pipe that are more than 10’ (ten feet) measuring between elbows, you must insert – at midpoint – a chimney stabilizer. When installing the stabilizer, pull out the support straps with a good amount of tension and hammer to the frame.

Mason-Lite Firebrick Liners
Custom Firebrick Lining
WARNING: DO NOT OPERATE FIREPLACE
WITHOUT FIREBRICK LINING. Doing so will void all
warranties and may cause a hazardous condition.
• Custom Firebrick Lining is not supplied by Masonry Fireplace Industries (MFI). There is, however, the option of Modular Prefabricated Panels that can be obtained from MFI. See exploded parts page for details.
• If Custom Firebrick Lining is desired, it is required that the brick be at least 1-1/8” inch thick and must be rated ASTM-C1261. Important: Allow at least 1/4 inch clearance around firebrick hearth to allow for heat expansion otherwise your firebrick may crack (see
Figure 60).
• The pattern for the firebrick lining is exclusively your choice.
Before you install the lining, remember to consider any holes your contractor may need to drill for gas, electrical or combustion air kit access holes.
• Please use a certified mason to lay-in the brick. He will follow the proper instructions from the fireplace liner manufacturer and also understand the type of adhesive or cement he is
to use.
• Make sure the fireplace is installed with the finished firebrick floor of the fireplace so that it is at least 11” (eleven inches) above the combustible floor system.
• Disclaimer: Masonry Fireplace Industries wishes to express that as the manufacturer of Mason-Lite Fireplaces, they cannot take any liability or responsibility for the way the firebrick or the firebrick mortar performs. It is not unusual in the course of the life of the firebrick, or the firebrick mortar, for heat stress cracks to appear. MFI cannot be responsible for this and other wear and tear to the firebrick and mortar.

Fireplace Finishes & Combustible Trim Clearances
Hearth Material & Dimensions – Strict codes control the types of materials that you can select for your Mason-Lite Fireplace’s hearth as well as the hearth’s length and width. All hearth extensions must be made of code-rated, noncombustible materials such as tile, brick, concrete or stone.
As with any radiant heat fireplace, all MASON-LITE
Fireplaces must comply with building code safety clearances,
per units that have openings of 6 sq. ft. (six square feet) or
greater. For Mantel clearances see Figure 17. Walls that Adjoin – Safety codes and all practical outlooks insist that your fireplace cannot be installed closer than 2 ft. (two feet) to any walls in the room the fireplace is housed in or to any walls of adjoining rooms.
Caution in Regards to Combustibles – If any part of the fireplace
or objects in the room (curtains, rugs, paint, cushions, etc.) start
to show warping or discoloration due to heat from the fireplace,
it is time to take immediate action. Do not use the fireplace until you have figured out how to address the problem. You are facing a potential fire hazard. MFI cannot be responsible for the make-up of material on the exterior of the fireplace you have chosen, nor can MFI be held responsible for the materials in a room that may be responding negatively to heat. However, in almost all cases, there is a solution to the problem, either by making adjustments to airflow or the modifications to the room itself.
Installing Outside Air
The Mason-Lite Fireplace needs enough replacement air to function properly and some local building codes may require outside combustion air to be provided. If no replacement air is provided, improper flue drafting may occur, creating negative pressure whereby smoke may enter the home, especially in homes that are very well insulated and tightly sealed. Check local building codes for specific requirements.
Install Combustion Air Kit MFP4-AK into the MASON-LITE Firebox through the side wall opening provided. A 4” dia. hole will also be required through the firebrick side lining (see Figure 64). The tubing that goes out of the firebox wall must feed into a flexible metal conduit as the source for outside combustible air. It can go straight out through an outside wall or into a ventilated crawl space. If crawl space is used, check codes for proper termination.
Figure 64
Be sure that you carefully check the source of the outside air
before you choose the site for your air intake. You don’t want a place where snow will collect, where bushes or trees will be growing or a location that is too close to any other structure.
Install a screened termination cap to keep out small animals.
10/30/2018
29
OPTIONAL OUTSIDE AIR KIT (MODEL MFP-AK/F)
The installation of an outside air kit should be performed during the rough framing of the fireplace due to the nature of it’s location. Outside combustion air is accessed through a vented crawl space (MFP4-AKF) or through a sidewall (MFP4-AK).
▲! CAUTION: Combustion air inlet ducts shall not
terminate in attic space.
The maximum height for the air vent cannot exceed
3 feet below the flue gas outlet of the termination.

Kit F2659.
The IHP chimney system consists of 12”, 18”, 24”, 36” and 48” snap-lock, double-wall pipe segments, planned for maximum adaptability to individual site requirements. Actual lengths gained after fitting overlaps must be taken into consideration (lineal gain) and are given in the lineal gain chart (see Figure 8). Lineal Gain is the actual measurable length of a part after two or more parts are connected. For Canada, use chimney parts designated “HT”.

ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY SYSTEM
Each double wall chimney section consists of a galvanized
outer pipe, a stainless steel inner flue pipe and a wire spacer.
The pipe sections must be assembled independently as the
chimney is installed. When connecting chimney directly to
the fireplace, the inner flue pipe section must be installed first
with the lanced side up. The outer pipe section can then be
installed over the flue pipe section with the hemmed end up.
Press down on each pipe section until the lances securely
engage the hem on the fireplace starter. The wire will assure
the proper spacing between the inner and outer pipe sections.
Continue to assemble chimney sections as outlined above,
making sure that both the inner and outer pipe sections are
locked together. When installing double wall snap-lock chimney
together, it is important to assure the joint between the chimney
sections is locked. Check by pulling chimney upward after
locking. The chimney will not come apart if properly locked. It
is not necessary to add screws to keep the chimney together
(exception: see Figure XX, Page XX).

Adding a Gas Pipe
You may elect to add a vented decorative gas appliance (gas log) to your Mason-Lite Fireplace. If so, follow the installation instructions from the Decorative Gas Appliance manufacturer. Familiarize yourself with requirements for installation as outlined by the National Fuel Gas Code, ANSI Z223.1. This gas pipe provision should only be used on a decorative gas appliance.
You can route the gas piping practically anywhere in the firebox – the floor, back wall or side walls. You will just need a masonry drill; the instructions from the gas appliance manufacturer will be very straightforward.
Fill in the holes you have drilled around the gas piping with the
regular MASON-LITE mortar.
Follow the Gas Log manufacturer’s instructions.
Adding Electrical Connections
Like the gas line, electrical feed lines can be run through the floor, back wall, or side walls. Follow local building and electrical code requirements.
Fireplace Grates and Screens
To complete your fireplace installation, a fireplace grate will be
required for safe operation. The fireplace grate can be obtained
from MFI or if choosing an alternate, it must be sized to 50% of
the hearth maximum. Additionally. a fireplace screen must be
installed for safety.
When ordering, please refer to the parts lists in the beginning
of this manual.
Fireplace Door Accessory
IMPORTANT: Only Mason-Lite MFP33-GD/ MFP39-GD/
MFP44GD/ MFP49GD Glass Doors are approved for use with
this fireplace.
For installation Instructions, see separate instructions included
with doors.
Mason-Lite Owner’s Operation & Precautions
Installers of the Mason-Lite are urged to leave the
owner’s manual with the unit after installation is complete.
WARNING: Do not attempt to operate your fireplace without a
fire safety screen installed.
CAUTION: The manufacturer cautions against using chemical
chimney cleaners. Never use charcoal or coal in the fireplace
under any circumstances.
First Lighting of the Mason-Lite – After construction is completed,
all elements of the fireplace and chimney system must be
completely dry. This means that the unit must stand without any
firing for a minimum of 28 days. Only after that period of time
can a first lighting take place.
The first fire must be small and well-controlled, started with a
small amount of kindling. Add no more than eight pounds of
wood, preferably small logs not more than 3” (three inches) in
diameter. You will probably burn no more than three to four of
these small logs. Do not let the fire burn for more than one hour.
After this first lighting – when the fireplace has started to “cure”
Do not set another fire for at least 24 hours.
Second Lighting – Start the fire slowly and gradually as you
did with the first lighting, but this time you can burn up to ten
pounds of firewood, probably four to five logs that are 3” (three
inches) in diameter. With the second lighting you can let the fire
burn two hours – no more.
After First and Second Lighting – When the fireplace has been
properly cured with 1st and 2nd lighting, you will be able to
add a full fuel load to the MASON-LITE which is about 10 to 15
pounds of firewood at any given time. Consider that this typical
fuel load is three to four dry hardwood logs that are about 6” (six
inches) to 8” (eight inches) in diameter.
Without a grate for your firewood to rest on, you cannot get the
air flow you need under the fire which makes for a hotter, more
satisfying fire.
Don’t “over burn” – Always remember, your Mason-Lite Fireplace
is an elegant addition to your home. It is not an indoor incinerator!
If you start to use the fireplace and begin a routine of “over
burning,” you can permanently and unalterably damage the unit.
Under no circumstances should you be burning household
trash, including chemicals and combustibles, cardboard
boxes, your office papers, scrap lumber or stray branches from
your yard, particularly pine.
WARNING: Burning of above mentioned materials will cause
an unsafe condition and will void your warranty!

Starting a Fire and Basic Operation
IMPORTANT: DO NOT BURN A FIRE WITHOUT FIREBRICK LINER.
(see Page 27 for details)
Before starting a fire in your fireplace, open the damper to its’
fully open position. Crumple some paper and place it on the log
grate. Use some soft, dry wood as kindling and put it on top of
the paper. Place some small logs or split logs atop the paper
and kindling. Top your fuel load with a couple of hardwood logs
or split logs (Oak or Hickory). Make sure you stack the logs so
they fall inside the grate as they burn.
Note: To get the most out of your wood, it is recommended that
you let it set and completely dry out for nine months to a year.
When you are satisfied with the arrangement of your wood
load, light the paper which in turn will ignite the kindling, then
the softer wood and finally, the harder wood logs. As the fire
burns, you can carefully lay additional logs on the flame, but
make sure you place them gently without forcing them into the
opening.
Annual Fireplace Maintenance
Your fireplace and chimney require seasonal and monthly
maintenance. It is recommended that inspection of the fireplace
and chimney take place on a monthly basis during the heating
season. Start at the top, looking for birds’ nests, leaves or any
other obstructions. Also check the spark arrestor, for creosote
or soot build-up.
A Professional Chimney Sweep may be hired to clean the
firebox and chimney at least twice a year. If doing it yourself,
use a plastic, wood or steel brush for the inside of the chimney.
For the spark arrestor, scrub with a wire brush. To dismantle the
chimney cap for cleaning of the flue, unscrew the four screws
that hold it in place. For cleaning access from below, open the
damper in the firebox. It is best to use a flexible handle chimney
cleaning brush made especially for the job.
If your fireplace system has any offset chimney sections, start
cleaning with the flexible brush from the top of the section
downward to the elbow. Then clean from the firebox up to
the offset/return section. Make sure to cover the floor of the
fireplace and out to the hearth with a damp sheet that has been
taped securely in place. When all the soot has settled, remove
the sheet and vacuum up. Don’t sweep the excess soot!
Never use any chemical cleaners when cleaning the chimney
system since their residue may cause a fire hazard.
During heating season as you conduct your monthly inspection
of the firebox and chimney, be sure to also check the outside of
the chimney, metal flashing and weather seals that surround it.
If you find any cracks or openings around screws or nails, seal
them to avoid any roof or chimney chase leaks.
SURFACE CRACKS
Mason-Lite fireplaces are manufactured using high quality
materials. During the drying process though, surface cracking
may occur. These small cracks (under 1/16” will not affect the
fireplace safety or performance). During the assembly process,
fill surface cracks with thin-set mortar and brush when drying
for a smooth surface finish.
REMOVAL OF CREOSOTE AND SOOT FORMATION
Creosote vapors are known to form in the relatively cool
chimney flues of slow burning fires, hence, creosote residue
collects on the flue lining.
Because of soot and creosote build-up, it is recommended
that the fireplace and chimney cleaning be done twice a year.
In colder climates, cleaning should be done more often.
Before performing maintenace on your fireplace make sure you
shut off gas and electrical connections and allow the fireplace
to cool completely.
Use only solid fuel in your fireplace. You may use a natural or
LP gas log lighter as a method to start your wood fire.
The Chimney Damper must be in the OPEN position whenever
there is heat in the fireplace.

Installing the Nailing Flange Extension
Once the fireplace is placed into the rough framed opening, the
supplied Nailing Flange Extension (Part No. L52087) must be fasten
securely into place, with nails or wood screws. as shown in Figure 7.
Note: The nailing flange extension can be substituted with a
piece of NON-Combustible material of the same size and thermal
characteristics, ie: cement board or equivalent. This is recommended
in applications where the facing materials will not adhere to the
metal nailing flange.

Montigo supplies a variety of direct venting and termination
options. The direct vent termination location MUST be selected
such that it is the highest point in the venting assembly. It
should also be selected such that it provides the shortest vent
run possible. Should it be impossible to ensure that the termina-
tion is the highest point or should it be impossible to meet the
venting guidelines laid out below please contact your Montigo
dealer to discuss power venting options.
NOTES FOR PLANNING VENTING:
Venting can originate from the unit through the top or
through the rear.
Venting can terminate through the roof or through an
exterior wall.
Refer to Appendix A - Termination Locations to ensure the
planned termination location is acceptable.
Once the termination location has been established, refer
to the appropriate section for installation details.
All fireplaces shipped from the factory are Top vent.
Silicone application is NOT required when joining Montigo
vent pipes and components.

Selection of components and details of venting lay out should
adhere to the following guidelines:
The maximum termination point is 32’ above the fireplace.
(NOTE: if the maximum termination height is used, the flame
pattern may be affected).
The Vertical termination must be a minimum 2’ higher than where the termination exits the roofing materials, (asphalt shingles, cedar shakes, etc). This distance should be measured from the high side of the roof slope where the flue flashing intersects the roofing materials. (see Figures 10 - 10c).
For a detailed diagram of allowed termination locations,
see Appendix A.
Termination location must be a minimum 6’ from a mechanical
air inlet.
A maximum of two offsets (each offset is made up of 2-90°
bends) may be made for vertical vent runs.

Connection and installation of the vent components
should adhere to the following guidelines:
Montigo recommends the use of a flex section for the final
pipe connected directly to the fireplace offering greater
flexibility of installation and absorption of movement.
Firestops must be installed as required by National & local
codes.
Montigo recommends that all exterior corners and joints be
sealed with exterior caulking. However, we encourage you to
consult your Building Envelope Engineer or Waterproofing
Consultant for further recommendations.
Section 3-3-2: Venting Components
The following components and associated Montigo part num-
bers for installation of a roof or wall mounted termination. Use
only Montigo Vent Components. Use of non-Montigo parts will
VOID the warranty and may impede operation of the fireplace. Use any combination of rigid and flex pipe as required and in
any orientation (Male connectors can face in any direction).
Flex sections may be stretched up to 50% of their total length
(e.g. a 24” section maybe stretched to 36”).
Connect all vent sections using a minimum of three sheet metal screws on the outer pipe flue.
Ensure the pipe ends male to female slide in a minimum of
1 1/2” of overlap.
Ensure all horizontal runs are supported with a minimum
of 3 supports per 10’ of venting.
When hanging/ supporting venting, ensure that 1” clearance
is maintained on sides and bottom of vent runs and 2” above
horizontal vent runs to any combustible material.
Rigid pipe may be cut less than half way from the female
end only.
Ensure when cutting sections of rigid pipe to maintain
integrity of internal supports.
Place the springs, supplied with the pipe kit, between the
outer and inner pipes to keep the pipes separate and avoid
any possible hot spots.
Please refer to your building evelope engineer or waterproofing consultant for
a review of ALL penetrations through exterior walls or the roof.

Installation
NOTE: If any of the original wire supplied with the appliance is
replaced, it must be replaced with the same type, or its equivalent.
Installing the remote On/Off Wall Switch
The L52DF* gas valve may be connected to a wall switch. Do
NOT connect any external power to the remote switch. The valve
will generate its own power on a millivolt circuit or will draw its
power from an AC Connection inside the fireplace, depending on
the model of the unit. Use only low voltage wire, and DO NOT
connect any external power to the remote switch.
Refer to Figure 18 or 19 for wiring requirements.
NOTE: The switch location must not exceed 30' from the fireplace.
The difference between IPI and CPI:
IPI (Intermittent Pilot Ignition) Mode: is a fuel saving mode
in which the pilot is only used when the main burner is on.
CPI (Continuous Pilot Ignition) Mode: The Pilot runs
continuously even when the main burner is off.
Installing the CPI Jumper Cable

Ignition Systems)
“Why use CPI mode”?
CPI means “Continuous Pilot Ignition” or “Standing Pilot” as it is
commonly known. IPI means “Intermittent Pilot Ignition”, which only
initializes the pilot when you are going to be using the appliance.
There are several reasons why you may choose to use CPI mode. When a flue is cold it can be difficult to light the appliance. It can take a bit of time (particularly on tall vents) to initialize vent action. This can result in “lifting” or “ghosting” of the flames during the first two to three minutes of operation. It is also possible to encounter times when the fireplace fails to light successfully. The fireplace will then attempt to re-light a second or third time depending on prevailing temperatures or altitude. When in CPI mode the pilot also keeps the system warm. During a “cold” start, condensation will normally form on the inner glass surface of the door. This condensation will quickly dry, however, the condensation tends to run down the glass and cause some streaking. CPI mode helps to resolve this issue. If CPI mode is used during the winter months the energy it takes to run the pilot is partially recovered as heat into the building, so it does not waste as much energy as running a pilot in the off season.
If you use a wall switch:
A connector is supplied with this unit that can be plugged into the
wire harness connected to the controller. When the CPI jumper is
connected, the pilot will light and remain lit continuously. Use the
wall switch to turn the main burner on or off. To switch back to IPI
mode you must unplug the CPI jumper.
If you use the optional remote:
A connector is supplied with this unit that can be plugged into the
wire harness connected to the controller. This Jumper Cable gives
the Remote Control the ability to operate the CPI / IPI switch and
set the unit to operate in either condition.
1). Remove the door and valve blind.
2). Remove the bag containing the Jumper Cable from
the wire harness connected to the controller as shown in
Figure 20.
3). Find the corresponding plug attached to the control wire
harness and connect the CPI jumper.

to remove a 1/8” N.PT. plug to be fitted with a hose
barb.
Montigo requires a service shut off valve be located
in an accessible location to isolate the gas supply.
Only install gas shut-off valves approved for use by
the state, province, or other governing body in which
the fireplace is being installed.
Section 5-3: GAS CONNECTION
See Figure 21 for location of gas line access.
Flexible gas connectors must not exceed 3 feet in
length, unless allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas
inlet port.
Purge all air out of gas line.
Check appliance connection, valve and valve train
under normal operating pressure with a commer-
cially available leak check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.
We recommend careful consideration be given to the effects of elevated mantel temperatures which may be in excess of product design, for example: candles, plastic
or pictures. This can cause melting, deformation, discoloration or premature failure of
T.V. radio, and other electronic components.
CAUTION
When pressure testing the fireplace, Gas line, and input system follow the appropriate local codes or your area. DO NOT connect the fireplace to pressures in excess of
1/2lb. This will damage the gas control valve.

WARNING
When installing the replace - gas lines, ttings, accesso-
ries or any other objects cannot impede the proper
movement of the door buckles.
An inspection of the explosion relief flappers and door MUST be made prior to
lighting the fireplace. A faulty seal on the door gasket and/or explosion ports will
result in products of combustion leaking into the living space and may result in
carbon monoxide poisoning.

Figure 22. Combustible mantels and facings.
Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over
the top and on the front of the fireplace provided that they do not
project beyond shaded area shown in Figure 22.
Fireplace Facing
When sizing the finish material for your fireplace, it is important
to remember the following: THE OPENING MUST NOT BE
OBSTRUCTED IN ANY WAY - to do so restricts the air supply for
the control compartments and heat exchanger it also prevents
access for servicing controls.
The face of the fireplace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must
not extend past the fireplace opening at all, because it will interfere
with the access to retainers for removal of glass door.
Figure 23. Combustible surrounds.
Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for fire hazard prevention to combustible materials.
New technology, to meet consumer and government demands for the
wise use of energy, has prompted us to manufacture many models
of fireplaces which are hot, fuel and energy efficient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above fireplace may be hot to touch.
Side wall clearances are 3". Combustible surrounds may be installed
with 3" clearance to the side of the fireplace as shown in Figure 23.

General
Have the fireplace and installation inspected yearly.
The inspection must include, but is not limited to, the
following: • A visual check of the entire vent system and termination.
• An inspection of the explosion relief flappers and the door gaskets to ensure a proper seal.
• An inspection of the burner, vent run, and primary air openings.
• An inspection of the gas valve, gas components, and pilot flame. For your convenience a 1/8" manifold pressure tap is supplied on the gas valve for a test gauge connection.
• Inspection of all optional equipment; fans, thermostats, etc.
■ For Natural Gas this appliance requires a minimum inlet
pressure of 5.5" W.C. and a manifold pressure of 3.5" W.C.
■ For Propane Gas this appliance requires a minimum inlet
pressure of 11" W.C. and a manifold pressure of 10" W.C.
■ Always keep the fireplace area clear and free of combustible
materials, as well as gasoline and other flammable vapors
and liquids.
■ Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect
the appliance and to replace any part of the control system
and any gas control which has been under water.
Inspection of glass doors and screen for damage and proper installation.
Cleaning
When the fireplace is first activated, there may be some smoke and
a visible film may be left on the glass. This is a normal condition,
and is the result of burning of protective coatings on new metal.
■ Glass must be cleaned periodically to remove any film
(which is a normal by-product of combustion) which may
be visible. Film can easily be removed by removing the
door, as shown on Page 25. Handle the door carefully, and
clean it with non-abrasive glass cleaners. One of the most
effective products is Kel Kem.
■ Silicone seals on inner door during initial firing will "off gas",
leaving a visual deposit of a white substance on combustion
chamber walls. This can easily be removed from the chamber
walls using normal household products.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
