READ ME FIRST
1.1 INITIAL FIRING AND CURING PROCEDURE
This product requires an initial heat curing cycle during which some materials used in the manufacturing process will burn
off and the powder paint goes through a hardening cycle. During the initial curing phase, some smoke and odor will b e
emitted. This is normal.
The installer should perform these initial curing cycle procedures as the final step in the installation process before
finishing materials are installed around this fireplace. See chapter 3.1.1 Mendota Fireplace Insert Curing Instructions.
Read and follow all instructions given in this Chapter and perform the 3 -step curing cycle.
After the 3-step curing cycle has been completed, all smoking will have stopped. Some slight odors may remain. With
subsequent use of this Insert, odors will slowly dissipate and disappear.
ODOR RISKS
If the Woodburning fireplace firebox and chimney flue are not inspected and cleaned as required, the
heat from this Insert body and vent system may caus e existing dirt, creosote or mold to emit odor .
If this appliance is not operated for an extended period (three months or longer), when first fired
again, expect odors of burnt dust and lint; just like when turning on your home heating system for the
first time in the Fall .
1.2 HOT SURFACES ARE NORMAL
Mendota Inserts comply with ANSI Z21.88-2016 Standards for maximum surface temperatures (ambient plus 117oF) on
exposed “combustible” surfaces adjacent to the Insert.
Be aware that the surface in front of, above and adjacent to this heater appliance can be too hot to touch. As long as all
required clearances to combustibles are met and the required finishing materials are used, this appliance will perform
safely. Note that the exposed surfaces immediately surrounding the Insert can have surface temperatures that are too hot
to touch. This level of surface temperature is considered normal and does not indicate any hazardous situation.
WARNING: The supplied barrier screen must be installed always when this fireplace is in operation.
Do not place any object directly in front (within 60”) or directly above (on the front edge o f the
mantel). This is a heat ing appliance. Areas directly in front and above this appliance will be very hot
and can d amage most household objects if placed too close. Keep Furniture pieces at least 60” away
in front of the barrier screen .
1.3 PERIODIC AND ANNUAL CLEANING ARE REQUIRED
See Required Periodic Inspections, Chapter 6.1 and Required Annual Maintenance, Chapter 6.3. Periodic and Annual
cleaning and general services are required at least once a year in the Summer or early Fall. Changing remote control
batteries at least every 6 months is required; or more frequently based upon usage frequency. Cleaning pilot flame sensor
rod, sparker rod and pilot hood body is required at least once per year. Cleaning of burner ports, gas orifice areas is
required once a year due to insects’ nesting probability due to Mercaptan addition in Natural Gas (Mercaptan attracts
insects).
1.4 KEEP THE FLUE WARM
It is required to activate the Continuous Pilot Mode (CPI) to leave the pilot light running during winter months when
outside daily high temperatures remain 50oF or lower. Doing so will eliminate heat loss from the home through the
fireplace Insert glass door and will increase flue draft during startups and will aid in eliminating system lock out.

3.1.1 Mendota Fireplace Insert Curing Instructions
ATTENTION
It is important that the blowers are turned on during this step to prevent the curing smoke from staining the
wall finish above the fireplace. Mendota reco mmends completing Step 1 prior to install ation of wall finish
materials.
Visible smoke and strong odor are to be expected during this step. If desired, disable smoke alarms before
this step, smoke from the initial curing c ycle will set off smoke alarms. Open doors and windows of the home
to circulat e fresh air.
3.1.1.1 Step 1: Expelling Initial Smoke and Odors
• Please refer to OPERATING INFORMATION, Chapter 5.4, if you have questions on how to operate your Mendota.
• Complete the installation of any barrier screen (required), surround, front or doors.
• Turn the fireplace on in the Manual (Off) thermostat mode.
• Set the Flame Height to Hi.
• Set the Fan Speed Control to Level 3.
• Run the fireplace with these settings for a minimum of 2 hours.
• Turn the fireplace off and let it cool.
3.1.1.2 Step 2: High Heat Curing Cycle
• Turn the fireplace on in the Manual (Off) thermostat mode.
• Set the Flame Height to Hi.
• Set the Fan Speed Control to Off.
• Run the fireplace with these settings until curing odors have diminished.
• When odors have diminished leave the fireplace turned on and continue to Step 3.
3.1.1.3 Step 3: Final Curing Cycle
• With the fireplace still turned on from Step 2.
• Set the Fan Speed Control to the lowest setting Level 1.
• If any new curing odors are detected continue to run the fireplace with this setting until the curing odors have diminished.
ATTENTION: Slight odors may still be noticeable on future startups of the fireplace. These will diminish over t ime as the fireplace
is used.
3.1.1.4 Additional Curing Information
It is not unusual for a fireplace to require more than 10 continuous hours on high for curing odors to diminish. There are
variables that can extend or shorten the curing time such as decorative fronts, doors, facing materials and their application.
Finish materials around the fireplace are subject to high temperatures. Finishing materials used over the fireplace in the no n-
combustible zone can see temperatures around 350° F. Materials used around the fireplace must be rated for these
temperatures. Failure to use adequate materials can result in odor problems. Please refer to Suitable Mantel, Facing & Hearth
Pad Materials, Chapter 3.2.17 of this manual for information on appropriate finishing materials.
Please be aware that any material used around the fireplace will heat up and has the potential to cause odor issues. Adhesiv es,
glue, wall substrate, wall finish material, paints and polishes are common materials that if used incorrectly will cause odor issues.
Mendota is not responsible for any odor issues caused by materials used around the fireplace.

3.2.9 Minimum Fireplace Size Requirements
To install this gas-fired Insert inside a wood burning fireplace, minimum width, height and depth requirements apply, see table
below. The required minimum width and height are constant. However, the depth required varies with the surround outer edge
depth. Decide which surround outer edge depth to use based on the available depth.
3.2.9.1 Floor Cover Plate
A floor cover plate is supplied with this Insert. Do not remove this floor cover plate for any reason. The cover plate positi on is
adjustable, front to back, by 1/4”.
To adjust the floor cover plate position, loosen four Philips head screws (do not remove, loosen only) and adjust the floor cover
plate position dependent on if you will be using a decorative door kit faceplate surround or a Basix surround. For a faceplate for
door kits, slide the floor cover plate forward fully and tighten the screws. For a Basix surround, push the floor cover plate
rearward fully and tighten the screws.

3.2.9.2 Surround Outer Edge Depth
For standard and stocked surrounds, see Minimum Fireplace Size Requirements Chapter 3.2.9, above. While the minimum width
and height requirements remain unchanged regardless of the surround type chosen, the surround outer edge depth chosen does
affect the minimum required depth. As the surround outer
edge depth increases, the minimum required fireplace depth
decreases.
To precisely determine the required surround outer edge
depth to fully fit this Insert into the fireplace cavity, follow
these procedures:
1. Adjust the floor cover plate position. Slide all the way
forward for a faceplate surround application and slide all
the way rearward for a Basix surround application.
2. Slide Insert inside fireplace cavity as far as possible.
3. Identify the front edge of the floor cover plate.
4. Measure from the front edge of the floor cover plate to
the face of the adjacent wall surface that the surround
outer edge will butt against. This measurement will be
equal to the required outer edge depth of the surround.
You should choose a surround with an outer edge depth
equal to or deeper than the measured distance in step 4, above. If the measured distance is greater than 1-3/4”, you must
consider a “custom surround” with a deeper outer edge depth. Mendota offers stock surrounds with outer edge depths of 5/16”,
½” and 1-3/4”. Other outer edge depths are offered as custom surroun ds.

3.2.11 Modifying ZC Woodburning Cabinets
This gas fired Insert may be installed in a ZC wood burning cabinet that has been modified by removing the refractory, glass
doors, screen rails, screen mesh, and log grates.
T he fireplace flue damper can be fully blocked open or removed for installation of the gas fireplace i nsert.
S moke shelves, shields, and baffles may be removed if attached by mechanica l fasteners.
C himney cleanouts must fit properly.
T rim panels or surrounds shall not seal ventilation openings in the fireplace
If the factory -built fireplace has no gas acce ss hole(s) provided, an access hole of 1.5 in (37.5 mm) or less
may be drilled thr ough the lower sides or bottom of the firebox in a proper workmanship -like manner. This
access hole must be plugged with non -combustible insulation after the gas supply line has been installed.”
C utting any sheet -metal parts of the fireplace, in which the gas fireplace insert is to be installed, is
prohibited by Ansi Z21.88 -2016 codes and other fire safety codes .
3.2.12 Clearances to Combustible Side Walls
The minimum distance required from the side edge of the visible glass to a combustible side wall is 18”. Combustible side walls,
mantel corbels, mantel legs and other combustible walls and decorative objects must fall behind a 45-degree line extending
outward from the side edges of the visible glass unless such objects are more than 18” away from the visible side edges of the
glass. See Figure 3-26 Side Wall Clearances.
If the required clearance cannot be m et to a pre -existing combustible side wall, an NFPA approved clearance
reduction shield , metal or ceramic board, must be added to the side wall.
3.2.12.1 Horizontal Clearance Reduction by 66%
NPFA 211 Approved: Install 20-gauge or heavier steel
shield that provides at least a 1” active airspace, on the
combustible wall surface. To provide for active airflow,
install at least 1” metal or ceramic standoffs or spacers
between the metal shield and the combustible surface
being protected. The bottom and top edges of the cavity
between the metal shield and the combustible surface
must be left open. The steel shield must be a minimum of
12” larger in each direction than the surface area of the
source of heat; or if the surface being protected is
smaller than surface area of the source of heat, this
shield must be larger than the combustible surface in
each direction.
By using this method of protection, if the required
horizontal clearance was 12”, the resulting clearance will
be reduced by 66% to 4” between the heat source and
the metal shield.
3.2.12.2 Horizontal Clearance Reduction by 50%
NPFA 211 Approved: Install an R-1 rated ceramic board or R-1 rated mineral board on the wall you are attempting to protect. by
using this method of protection, if the required horizontal clearance was 12”, the resulting clearance will be reduced by 50% to
6” between the heat source and the R-1 Rated wall board.

3.2.14 Hearth Pad Requirement
A non-combustible hearth protector with a thermal insulation rating of R-1 is required when installing this fireplace directly on
the floor and must extend a minimum of 16" in front of the fireplace.
For every 1” the fireplace is raised off the floor, the depth of the required hearth protector may be reduced
by 2”. If fireplace is raised off the floor 6" or more, no hearth protector is required for fire protection .
Pre-existing non-combustible hearth pads are approved. New hearth pads installed are required to have a thermal insulation
value of R-1.
Caution: Vinyl floors and f loating laminated f loors may war p if installed in front of this unit even if fireplace
is raised 6” or more due to local hea ting up of the floor material s causing thermal expansion locally. Use a
hearth pad instead of vinyl or laminate flooring in the hearth pad area in front of this fir eplace even if this
unit is raised 6” or m ore.
Caution: Modern carpets use polypropylene, ny lon or polyester fibers in the upper visible layer. These fibers
when exposed to radiant heat can curl and stiffen. It is not possible to prevent radiation effects to the carpet
fibers even when this unit is raised high. Avoid installing carpets in the hea rth pad area in front of this
fireplace Insert .

3.2.15 Re-facing a Woodburning Fireplace
Remodeling an old wood burning fireplace and its surrounding wall facings is a cost-effective way to modernize and enhance the
beauty of a home and to raise the resale value of a home. This form of remodeling is called “re-facing”.
Notes for re-facing:
1. All re-facing framing members’ material within 24” of the opening of the existing wood burning fireplace must be galvanized
steel.
2. Directly above the top of the existing wood fireplace, a galvanized steel stud must run horizontally across the opening of the
fireplace. On the bottom face of this horizontal galvanized steel stud, a heat rise barrier made from ½” thick noncombustible
mineral board must be installed in a manner which completely blocks heat from seeping and rising upwards between the
existing wall face and the newly installed wall surface structure.
Warning: Fail ure to install this Heat Rise Barrier board can lead to a fire hazard.
3. All facing materials used on the new framed structure and within 24” of the existing fireplace opening, in all four directions,
must be of the noncombustible type. See Chapter 3.2.17 Suitable Mantel, Facing & Hearth Pad Materials for recommended
suitable facing materials.
Note: The suggesti ons given in this section are Mendota Fireplace’s recommendations only. All local building
code requirements must still be researched and followed.
Figure 3-32 Re-facing Information
02/01/2019
85-03-01060-D FV44i Décor Gen 3 Page 33
3.2.17 Suitable Mantel, Facing & Hearth Pad Materials
Use of ceramic glazed tiles as facing materials around a Mendota Insert is approved. Use caution when selecting tile adhesives.
Avoid premixed tile adhesives which contain products th at can off gas for long periods when exposed to heat. Use portland
cement based unmixed tile adhesives or RTV Silicone to attach ceramic glazed tiles as facing in hot areas around this Insert. If
using RTV silicone, allow a minimum 48 hours cure time for the silicone to cure before firing this Insert after tile application.
3.2.17.1 Marble, Granite and Natural Stones
Marble, granite and other natural stone products are approved for use as mantel, facing and hearth pad materials with the
following limitations and understanding of these cautionary statements:
Neve r use a one -piece marble, granite or natural stone that is water jet or mechanically cut in a U -shape as
facing material to cover the sides and t op areas around this product. Doing so can lead to crack formation
at the inner corners of the U shape due to t hermal expansion.
Figure 3-33 Three Piece Stone
Most marble slabs and marble tiles contain a polyester resin coating while most granite slabs and granite tiles contain epoxy
resin coatings. The polyester resin coatings and the epoxy resin coatings provide structural strength to the stone slab s and
prevent cracking, chipping and breakage during shipping and handling. These coatings also provide a glossy or satin surface finish
and help seal the stone surface.
The polyester resin used on marble slabs can discolor when exposed to temperatures greater than 150 o F and
will structurally fail at temperatures above 230 o F. The epoxy resin coating used on granite slabs are resistant
to discoloring and structural failur es up to 3 50o F.Mendota does not assu me any liability for discoloring,
flaking or cracking of marble or granite.
Temperatures on facings around Mendota Gas Inserts can reach 3 50oF directly
outside the top convection air gap and as high as 210oF at the maximum
allowed mantel protrusion level above the top convection air gap. These
temperatures will discolor polyester resin coated marble facings and can
cause the polyester resin coating to fail near the top convection air gap.
Mendota Fireplace cannot guarantee suitability of u se of any
marble slabs or tiles that have a polyester resin coating applied to
it and cannot guarantee against discoloration or structural failure
of marble or po lished stone facings that have a polyester resin
coating. Consult with your local stone suppli er.
Prior to use of any marble, granite or polished stone facing material, especially
white colored ones, run heat exposure tests on a sample piece. Expose sample
Figure 3-34 Top Air Gap
TOP AIR
GAP
02/01/2019
85-03-01060-D FV44i Décor Gen 3 Page 34
pieces to temperatures between 275oF and 350oF for a period of eight hours. Compare the heat exposed sample to a control
unheated piece and judge for color changes. Do not use if any color changes are evident.
Mendota recommends the use of honed bare marb le and bare stone facing materials or honed bare granite
and epoxy resin coated granite only.
Mendota cautions that due to natural structural defects that can exist within marble and stone pieces, cracking and/or flaking of
the marble or stone is possible and must be considered prior to selection and application around Mendota Inserts. Mendota
further cautions that proper adhesives be used to attach stone facings. Pay attention to the potential of off -gassing of chemical
vapors from mastic and other adhesives. Improper selection can lead to emission of chemicals with unwanted smells.

3.2.18 Suitable Paints and Sealant Materials
3.2.18.1 Paint Types Approved for Use
Industrial Acrylic Paints, Alkyd based Paints. When selecting paint for applications on facings, mantels, corbels or floors within 2’
in front of a fireplace raised 6” or higher, avoid off the shelf paints which may have modifier additives used to increase “h iding”
ability, accelerate drying times and curing times. Consult with a reputable paints and sealants supplier and acquire industrial
acrylic paints or alkyd based paints.
3.2.18.2 Sealants Type Approved for Use
Heat resistant polyurethane sealants which are not damaged by prolonged exposure to raised temperatures. Many are flame
resistant, meaning that they resist ignition when exposed to high temperatures and can insulate the substrate and delay damag e
to it. When selecting polyurethane for applications on facings, mantels, corbels or floors within 3’ in front of or above a fireplace,
avoid off the shelf urethane sealants which may have modifier additives used to accelerate drying times and curing times.
Consult with a reputable paints and sealants supplier and acquire heat resistant polyurethane sealants.
3.2.18.3 Wood Application Cautions
If wood used around or in front of the fireplace has been chemically cleaned or bleached prior to staining or painting, it is of the
utmost importance to make certain that the cleaner or bleach does not r emain in the wood substrate under the final paint or
sealant applied. If any cleaner or bleach remain within the wood structure, application of heat from the fireplace, even low -level
heat, will cause the cleaner or bleach compounds to expand or evaporate causing separation of the paint or seal ant from the
wood surface and may cause peeling or bubbling of the paint or sealant.
Moisture content of the wood substrate is also of critical importance. High moisture content wood when heated will yield
evaporation of the moisture and hydraulic pressure under the paint or sealants which can lead to peeling or bubbling. Always
select the lowest moisture content wood substrate.
Refer to Mendota Fireplace Insert Curing Instructions, Chapter 3.1.1.

3.2.19 Installing A Flat Panel TV Above This Fireplace Insert
Note: The model depicted in the images in this document may not match the particular model you have selected. However, these
instructions do apply commonly to all Mendota ZC Fireplace Inserts.
All flat panel TVs are solid state electronic appliances and are vulnerable to high ambient
temperatures.
This fireplace Insert is a gas fired heater and high ambient temperatures are to be expected in the
immediate vicinity of this fireplace Insert. If the installation of a Flat Panel TV is desired above this
appliance, proceed with caution. Follow the specific instructions provided in this section.
Failure to follow instructions can lead to heat related damage to TVs installed above this fireplace
Insert.
There are two options available for adding a flat panel TV above this Fireplace Insert: Add a mantel
below the TV, re-face the fireplace wall and create a framed recess cavity for housing the TV.
3.2.19.1 Option 1: Add a mantel
Add a mantel that is 2” deeper{minimum} than the full depth of the TV and as wide as the full
width of the TV {minimum} above this Fireplace Insert. The mantel sha ll be mounted so that its top
surface is 18” (minimum) up from the top edge of the t op air gap of this Fireplace Insert.
If the mantel is constructed of combustible materials, make certain that the entire mantel meets
the Clearances to Combustible Mantels requirements.
3.2.19.2 Option 2: Re-face the fireplace wall and create a recessed cavity

3.2.20 Venting
The FV -44i Insert must be vented vertically to the outside and must use one of the approved co-linear
flexible ducting system s or a coaxial fl exible ducting system . Mendota recommends that both exhaust and air
intake flex liners be run all the way to the vent cap. Seals between flex liners and unit top and vent cap must
be permanent and as air tight as possible. Do Not Use any silicone sealants at flex pipe joints. Stove
gasket cements may be used at pipe joints but is not required . D o use both securing screws and hose
clamps at all four flex connection points.
3.2.20.1 Maximum and Minimum Vent Lengths
Minimum vent run length required is 10’. Maximum vent run
allowed is 55’. Only vertical termination is allowed. No
horizontal runs are allowed with the vent system. Horizontal
offsets of less than 4’ are approved if the offset is angled at least
30-degrees vertically.
3.2.20.2 Run Liners to Vent Cap
When existing wood burning chimney size allows, run both the
4” exhaust liner and 3” air intake liner to the vertical vent cap. If
existing wood burning chimney size is too small to run both 4”
and 3” liners, consider converting to a coaxial flex system using a
4” exhaust flex and 6” air intake flex with spring spacers
between the two flex pipes.
3.2.20.3 Air Intake Liner Stubbing
When existing wood burning chimney, size is too small to run
both 4” and 3” liners, it is an option to cut the air intake flexible
duct short and run only the 4” vent flexible duct to the vent cap
connector. This is generally called “stubbing”. However,
understand that doing so may lead to venting problems when
weather storms approach. Variations between the air pressure
inside the home and atmospheric air pressure s outside the
home can cause venting problems and performance failures.
Avoid “stubbing” if chimney flue size allows installation of both
liners fully to the vent cap.

3.2.20.5 Fireplace and Chimney Cleaning Requirements
The plan to install a gas fireplace Insert must include inspection and cleaning of the fireplace cavity and the entire chimney
system. The chimney top, especially masonry chimneys and wood framed chimney tops must be inspected and the top surface
must be repaired or replaced, if necessary. Unlined chimney flues are the most vulnerable to mortar corrosion and damage.
These flues must be inspected and repair must be done before dropping the flex vent liner for this Insert.
If you encounter a badly deteriorated or completely damaged firebox, do not proceed. These damaged structures must be
reviewed by structural Engineers and Local Building Code officials must approve the repair work prior to this Insert being
installed in such a damaged cavity.
Mendota requires that the fireplace cavity and chimney system be cleaned per the Chimney Safety
Institute of Ame rica recommendation prior to installati on of a Mendota gas fired Insert . The Chimney
Safety Institute of America recommends that open masonry fireplaces should be swept at 1/8" of sooty
buildup, and sooner if there is any glaze present in the system. Thi s is considered to be enough fuel build up
to cause a chimney fire capable of damaging the chimney or spreading to the home. Factory -built fireplaces
should be swept when any appreciable buildup occurs. The logic is that the deposit is quite acidic and can
shorten the life of the fireplace.

Figure 3-38 Badly Deteriorated
Firebox
WARNING: Fail ure to inspect and repair or replace damaged or dilapidated chimney flue, firebox or
chimney top caps can lead to odor emissions, water penetration and damage to electronic component s of
this gas Insert or damage to other home structures. This omission to inspect, repair or replace as necessary
will void all applicable warranties on this product.
3.2.20.6 Types of Chimney Flues
Chimney flues can vary in shape, size and type. During inspection, make note of the type of the flue system used. Professionally
clean and make any repairs before installing a Mendota gas Insert. Especially, pay attention to unlined flues which may have
missing or severely damaged mortar joints.

85-03-01060-D FV44i Décor Gen 3 Page 39
3.2.20.7 Types of Chimney Tops and Vent Caps
Chimney tops vary in shape and size and configuration. The vent cap selected for installation will require some modification to fit
various chimney top types. Consult with your vent supplier.

For installation of this Insert ’s vent cap with chimneys that have an e xisting metal, stone or concrete cap
(Figure 3 -44, Figure 3 -45, Figure 3 -46), Do Not use “low profile ” vent caps. They are vulnerable to exhaust
reci rculation and ghosting flames problems. Always use full size vent caps and allow a minimum 3” clearance
from vent cap top to the ch imney cap. For wider chimney caps and slabs, greater than 1 6 ” wide, increase the
clearance above the vent cap to 6” minimum. If necessary, raise the slab to supply the required clearance.

3.2.20.8 Side by Side installation of two Vent Caps
When two or more vertical vent caps are located within proximity of one another, it is requ ired that a galvanized steel 18-gauge
or heavier barrier wall be installed between the two vent caps to eliminate recirculation of exhaust gases from one cap to
another.
The galvanized steel barrier shall be 6" taller than the highest point of the vent caps and shall be 3" wider past the outer edges of
the vent caps.
If two gravity direct vent system gas appliances are terminated next to each other, the minimum required distance between the
vertical center line of the vent caps is 18” to prevent recirculation of exhaust from one vent cap outlet into the air intake of
another vent cap.
If a wood burning flue opening is adjacent to a gravity direct vent system gas appliance vent cap and the distance between
vertical center lines of the two terminations is less than 36”, we recommend a metal divider plate be installed to prevent wood
burning exhaust from entering the gas appliance air intake path. Alternatively, you may also vertically extend the wood burning
flue liner up 24” higher than the top surface of the gas appliance vent cap.

3.2.20.9 Decorative Cover for Vent Cap
It is acceptable to install a decorative stone, metal or terra cotta cover to disguise the vent terminal/cap used on Mendota
Inserts if the decorative cover meets the following minimum requirements:
1. The decorative cover shall be manufactured from noncombustible materials.
2. The decorative cover shall provide a minimum of 3” clearance from the outer surface of the vent cap to the inner walls
of the decorative cover on sides all of the vent cap.
3. Fresh air openings shall be provided at a level equal to or below the fresh air openings in the vent cap. The fresh air
openings shall provide a minimum open area of 60 square inches. This fresh air opening area shall be broken into at
least two equal openings (or more if po ssible). Each opening shall have a minimum height of 2” and a length that
provides the required opening to yield a total of 60 square inches, minimum.

4.7 LEVELING BOLTS
4.7.1 Leveling Bolts Definition
Four leveling bolts are included in the manual package. The leveling bolts allow for a ¼” minimum to 1” maximum leveling ability.
Leveling bolts are designed to adjust for uneven fireplace floors and yield plumb Insert Body. Use the leveling bolts only if t he
fireplace floor is more than ¼” out of level from one side to another or from front to back. If the fireplace floor is less t han ¼” out
of level, use metal sheet shims in various thickness and build up to needed leveling thicknesses at various points around the
appliance.
The leveling bolts supplied are designed specifically for application with this product. only use leveling bolts supplied by Mend ota
and for leveling purposes only. Never use leveling bolts for purposes of lifting unit up to make up fo r ash lip heights or other
lifting or raising needs. Such use can cause extreme thermal expansion of firebox floor and can result in oil canning noise o r
louder thermal expansion and constriction banging noise. SUCH NOISE PROBLEMS ARE NOT COVERED UNDER MENDOTA
WARRANTY
Note: When lifting this Insert more than 1”, other support blocks will be required. For all applications when
you raise the unit more than 1”, reline the entire firebox floor with refractory bricks to build up a full level
floor for the Inser t to sit on. Do not use individual support block only under the four corners of this unit.
WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts
specifically approved with this appliance may result in propert y damage or personal injury. Never use other
after -market leveling bolts. Doing so can lead to vibration noise problems or damage to internal
components.DO NOT USE LONGER BOLTS TO LIFT INSERT UPWARD. THIS CAN CAUSE OTHER SIDE EFFECTS LIKE
HEAT EXPANSION/C ONTRACTION NOISES. To lift Insert up, use Firebricks and mortar or a metal box designed
specifically for this purpose .
4.7.2 Leveling Bolts Installation
Perform this step after you have measured the firebox floor for level surface characteristics. Tip the Insert body on its back on
the wooden pallet. Thread one leveling bolt in to each leveling bolt receiving fastener. Thread the bolt in as far as necessa ry to

4.12 VENTING
WARNING: Proper installation of the vent system, as re quired in this manual, is vital to the performance of
this Insert. Oversights or failure to conform to all in stallation requirements will void the applicable warranty.
The FV -44i Insert must be vented vertically to the outside and must use one of the appro ved co-linear
flexible ducting system s or a coaxial flexible ducting system .
This heater must be properly c onnected to a venting system in accordance with the manufacturer's
installation instructions. Operation of this heater when not connected to a prop erly installed and maintained
venting system can result in carbon monoxide (CO) poisoning and possibly death.
If the vent system of this appliance is disconnected for any reason, the vent and air intake systems must be
proper ly reassembled and resealed bef ore this appliance is put into use.
When existing wood burning chimney size allows, run both the 4” exhaust liner and 3” air intake liner to the vertical vent cap. If
existing wood burning chimney size is too small to run both 4” and 3” liners, consider converting to a coaxial flex system using a
4” exhaust flex and 6” air intake flex with spring spacers between the two flex pipes.
NOTE: Mendota recommends that both exhaust and air intake flex liners be run all the way to the vent cap.
Seals between flex liners and unit top and vent cap must be permanent and as air tight as possible. Never use
silicone sealants i n pipe joints. Use of sealants at flex pipe joints is not required . Do use both securing
screws and hose clamps at all four flex connection points.
When existing wood burning chimney flue size is too small to run both 4” and 3” liners, it is an option to cut the air intake flexible
duct short and run only the 4” vent flexible duct to the vent cap connector. This is generally called “stubbing”. However,
understand that doing so may lead to venting problems. Variations between the air pressure inside the home and atmospheric
air pressures outside the home can cause venting problems and
performance failures.
CAUTION: Each installation must conform to all local, state
and national code s. Refer to the national fuel gas code and
local zoning and code authorities for details on installation
requirements. The Mendota Ins erts must be vented to the
outside in accordance with the latest edition of the National
Fuel Gas Code. In the absence of local codes, the installation
must conform with National Fuel Gas Code ANSI Z223.1
(NFPA 54), or Canadian Code CAN1 -B149 or most curr ent
edition, also known as NFPA 54. Do not connect this Insert
to a chimney flue serving a separate solid fuel or gas -burning
appliance.

4.12.2 Dropping Flex Vent Liners
Figure 4-22 Installing Flex Liners
1. Measure the chimney height from the top of the chimney (or the existing flue liner) to a point 12" (300 mm) above the
floor of the fireplace hearth. It may be necessary to drop a rope and measure the rope itself. Be sure to allow for all
offsets in existing chimney. Cut the 4" and 3” diameter flex liners to this measured length.
2. Attach a sheet metal strap loop to the flex end of the liner(s) and tie a rope to it. Two in stallers should proceed to the
roof and drop the rope (with weight on the end to make sure it goes all the way down) and insert the 4” and 3” liners
past the flexible portion, into the existing chimney.
3. One installer should then return to the fireplace opening and pull the rope to guide the liner(s) into place through the
smoke shelf and the damper opening to a point 12" (300 mm) above the fireplace hearth. The person below should
wear leather gloves and Safety Glasses during this process to avoid being cut and to safeguard eyes from flying debris.

4.12.3 Attaching Flue Liners to Vent Cap
Four hose clamps are supplied with each Mendota vent kit . Four #8 sheet metal screws are needed which are not supplied with
Mendota vent kits.
For vent kits (other brands) obtained from other distributors or suppliers, acquire four 4” diameter hose clamps and eight #8
sheet metal screws. Follow these procedures to secure the flexible 4” liner and 3” liner to the Insert Top vent adapter and t he
vent cap starter collars:
CAUTION: Al ways inspect flex liners f or tears and punctures. If any tears or punctures are found, do not use
the liner. Replace the liner with a new one.
Make certain vent cap/ flashing is permanently
sealed to chimney top using exterior grade
roofing sealants.
1. At the chimney top, attach 4” flex vent to 4”
starter collar on vent cap.
2. Secure 4” vent flex to 4” starter collar
employing one 4” hose clamp and a ratchet.
Position hose clamp close to the flashing
plate. Compress the flex as much as possible
around the starter collar to obtain a tight joint
between starter stubs and flex inner surface.
3. Secure the flex liner to the starter collar with
sheet metal screws in two equally spaced
radial locations and below the hose clamp to
stop hose clamp from sliding off.
4. Repeat this procedure for the 3” flex.
4.12.4 Sealing the vent cap base plate or flashing to the Chimney Top
Note: It is required that the chimney -top be permanently sealed to prevent cold air infiltration into the
home.
The vent cap base plate of a square shaped vent cap or the base plate of a co-linear to coaxial vent adapter (chimney top
adapter) must be sealed air tight and permanently to the existing chimney top.
To seal to the top of a chimney, follow these steps:
1. Trim the base plate of the vent cap or vent adapter to size and shape desired.
a. To seal on top a large flat surface, trim the base plate as desired but allow a minimum of 1” overlap outside the chimney
top opening.
b. To seal on top of a terra cotta liner, trim the base plate 1-1/2” bigger all around the terra cotta liner outer perimeter.
Notch corners and bend the extra 1-1/2” down to make a screw-on flanges.
c. To seal on top of a steel tubular vent pipe, trim to a size 2” larger in diameter than the existing vent pipe and cut slots
into the outer edge of the base plate and bend down multiple tabs to make screw-on flanges.
2. Clean the top surface and side walls of the existing chimney using a stiff wire brush or sand paper.
3. Blow off all dust and apply a 1/4” diameter bead of exterior grade silicone sealant around the chimney top opening (flat top,
terra cotta liner) or the side wall top edges of metal vent pipe.
4. Place base plate on top of chimney top and secure base plate to chimney using appropriate screws.

4.12.5 Air Intake Damper Adjustment Suggestions
The Insert's vent adapter has a damper plate located on
the 3" air intake tube. The vent damper comes from the
factory set at a 45-degree position. Set the damper
according to the length of venting used.
❑ Below 20’. leave in the factory position of 45-
degrees.
❑ Above 20’. close approximately 15-degree for
every 10’. above 20’.
❑ Above 50’. close fully.
Note: Some variations due to offsets in chimney and other factors may require fine tuning the primary damper position.
4.12.6 Attaching Flue Liners to Unit Top Vent Adapter
Once the two flex liners are dropped to the fireplace cavity,
attach the 4” exhaust flex and the 3” air intake flex to the
unit top vent adapter using hose clamps and sheet metal
screws
1. At the fireplace cavity attach 4” flex vent to 4” starter
collar on sliding vent adapter.
2. Secure 4” vent flex to 4” starter collar employing one 4”
hose clamp and a ratchet. Position hose clamp close to
the flashing plate. Compress the flex as much as
possible around the starter collar to obtain a tight joint
between starter stubs and flex inner surface.
3. Secure the flex liner to the starter collar with sheet
metal screws in two equally spaced radial locations and
above the hose clamp to stop hose clamp from sliding

5.6 IPI AND CPI MODES
Intermittent Pilot and Continuous (Standing) Pilot Features
This gas fireplace is equipped with an electronic ignition system that first lights a pilot then uses the pilot to ignite the main
burners. The pilot can be set in the CPI (Continuous Pilot Ignition) mode to allow the pilot to remain on indefinitely by setting the
remote control to CPI mode. If the remote control is set to the IPI (Intermittent Pilot Ignition) mode, the pilot will only light and
remain ON while the main fireplace burners are operating.
IPI Mode: This mode turns the pilot off when the fireplace is not functioning and only lights the pilot automatically when a call
for heat is made by the remote control.
CPI Mode: If set to CPI mode, the pilot will ignite and remain on always.
5.6.1 Setting to IPI or CPI mode
With the remote control OFF, press the MODE button. You will see either “CPI” or “IPI”
displayed on the screen. Press the Up-arrow button to set “CPI” mode and press the
DOWN arrow button to set “IPI” mode. Once set to the desired setting, press ON/OFF
button to activate the fireplace.
Note: The snowflake icon will be visible on the display at all times when in CPI mode.
Recommended: Mendota recommends that CPI mode is used during the winter months
when the average daily high temperature falls below 50°F. This will keep the fireplace
chimney heated for proper updraft during burner ignition , and it will also eliminate excessive condensation of exhaust vapors on
the door glass. Leaving the fireplace in CPI mode will keep the fireplace body warm and eliminate cold drafts and heat loss to the
cold air that is trapped inside the firebox.
5.7 HOW DO I CHANGE FROM CELSIUS TO FAHRENHEIT?
To change between °C to °F, follow these steps:
1. Press the ON/OFF button and turn off the fireplace.
2. Simultaneously, press both the mode button and the thermostat button.

Remove logs & coals or other burner media and clean away any foreign matter (lint, Carbon, etc.) on the burner and l ogs. Be sure
the burner ports are "open". Clean the pilot and under side of the logs for any Carbon deposits.
NOTE: Logs should be visually checked for Carbon "bui ld-up". If carbon deposits are visible on logs, unit
should be turned off and a qualified ins taller, service agency, or the gas supplier should be contacted . Be
sure logs are re -installed per instructions.
Check glass gasket seal. Visually inspect glass gasket, especially at the corners of the glass piece. Glass gasket is installed as a 4-
piece assembly. Check joints between the gasket pieces at the corners. They should butt against each other to create a seal. Gaps
between gasket pieces can cause exhaust leaks and lead to acrid smell concerns.

6.4 OVER FIRING OR UNDER FIRING OF BURNER
NEVER "over fire" or “under-fire” units by increasing or decreasing the main orifice sizes or by adjusting gas pressure to increase
BTUH above nameplate specifications.
Over firing can cause permanent damage to firebox and deterioration of parts and void the warranty.
Under-firing can potentially cause delayed ignition and lead to property loss and person injury and will void the warranty.
If you are using a “backyard” Natural Gas well as the gas source, you must submit formal gas analysis data
sheets to Mendota Fireplace s for review and calculation of proper main burner orifice sizes prior to first
fir i ng. It is known that unpurified Natural Gas from “back yard” wells can contain high energy levels causing
over firing. Further, unpurified gas can contain high levels of Sul phur and other compounds which can
damage the burner materials and the ceramic glass. Use of unpurified gas will void the warranty for thi s
product.
6.5 IGNITION SYSTEM LOCKOUT MODE AND RE-LIGHTING
If ignition system goes into lockout mode , be sure to wait a m inimum of five minutes before attempting to
re-light. If lockout occurs frequently, contact you Mendota Dealer for diagnosing the problem.
Frequent lockout can be caused by many factors and must be properly diagnosed, and the primary cause identified. It s hould
never be assumed that the ignition control system is faulty without proper diagnosis.
6.6 BURNER FLAME HEIGHTS REFERENCE DIAGRAM
Figure 6-2 Burner Flame Heights: This image provides a visual reference for the
burner flames burning at maximum height after the burners have been operating for
30 minutes or longer. A normal rear flame will be 1 to 2 inches above the rear log top
edge. This, however, is dependent on the gas type, air shutter opening setting and
vent system configuration. Actual flame heights can be slightly higher or lower when
compared to this reference image.
