Section 2: Framing
Figure 1 Sec.2 Fireplace installation, (Rough Frame-In dimensions) Both Sides are Typical.
Step 2. Once the fireplace is placed on the platform, ensure there is access to install the vent pipe, and inline power vent module if applicable
and the gas line. Note the gas line connection location and room to provide a gas service shut-off valve; according to local gas codes. Before
fastening in place line up the front face and rear face of the fireplace (top and botttom), Figure 1. then secure in place with 1/4" wood screws.
Step 1. You will need to construct a platform in the framing for the fireplace to sit on. To determine how high to build the platform you must
determine the how high you would like the bottom edge of your glass viewing area to be. The bottom edge of the glass sits 15 1/8" above
the top of the platform. Please note: The top of the platform may not exceed 24" in a room with 8' ceilings.

Fireplace Facing
When selecting the finish material for your fireplace, it is important
to remember the following:
If the surround of the fireplace is to be painted to match the room decor,
heat-resistant paint must be provided . Also, 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 and access to
the lower compartment.
Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for fire hazard prevention to combustible materials.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above fireplace may be hot to touch.
Warning:
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. and
radio components.
Note: Images are shown without screens for clarity purposes.
However, your fireplace should not be operated without proper
installation of screens.

Section 4-2-2: Venting Components
The following venting components and associated Montigo part
numbers are available for horizontal installations:
Connection and installation of the vent components should
adhere to the following guidelines:
■ 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 runs are supported with a minimum of 3 supports
per 10’ of venting.
■ When hanging/ supporting venting, ensure that 1” clearance
is maintained on all sides to any combustible material.
■ 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.
■ 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.
■ All exterior joints in venting should be sealed with high heat
silicone RV230.

Fuel Type
Verify that your fireplace is compatible with your available gas type.
Natural Gas or Propane shown by "N" or "L" in your model number
on rating plate.
Gas Pressure
Optimum appliance performance requires proper input pressures.
Gas line sizing requirements will be determined in ANSI Z221.3
National Fuel Gas Code in the USA and CAN/CGA B149 in Canada.
Pressure requirements (during operation):
The manifold outlet pressure is set from the factory to the appropriate
pressure but should be verified.
To check pressures, control valves have a provision 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.
GAS CONNECTION
See Figure 1 Sec.6 below 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" Male NPT gas inlet.
Purge all air out of gas line before connecting port.
Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.

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.
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. and
radio components.
Side wall clearances are 6". Combustible surrounds may be installed
with 6" clearance to the side of the fireplace as shown in Figure 2 Sec.7.

Section 11: Cleaning and Maintenance
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 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, 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.
See Lighting Instructions section.
Cleaning
When the fireplace is first activated, there may be some smoking 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
22. Handle the door carefully, and clean it with non-abrasive,
non-ammonia based 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 using normal household
products.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
Annual inspection list for determining safe operation of a direct vent decorative gas appliance
1) Inspect and operate the pressure relief mechanism to verify relief mechanisms are free from obstruction to operate.
2) Clean glass window with a suitable fireplace glass cleaner. Abrasive cleaners must not be used. Be careful not to scratch the glass when cleaning.
3} inspect the operation of the flame safety system Pilot or Flame rectification device.
4) Inspect and ensure the lighting of the main burner occurs within 4 seconds of the main gas valve opening. Visual inspection should match that outlined in the appliance instruction manual. Inspect primary air openings for blockage.
5) Inspect condition of vent and vent terminal for sooting or obstruction and correct if present.
6) Vacuum and clean any debris in the firebox that is not supposed to be there.
7) Test and measure the flame failure response time of the flame safety system. It must de-energize the safety shutoff in no more than 30 seconds.
8) Check all accessible gas-carrying tubes, connections, pipes and other components for leaks.

(1) Revise NFPA-54 section 10.5.4.2 by adding a second exception as follows:
Existing chimneys shall be permitted to have their use continued when a gas conversion burner is installed, and shall be equipped with a manually
reset device that will automatically shut off the gas to the burner in the event of a sustained back-draft.
(2) Revise 10.8.3 by adding the following additional requirements:(a) For all side wall horizontally vented gas fueled equipment installed in every dwelling, building or structure used in whole or in part for residential
purposes, including those owned or operated by the Commonwealth and where the side wall exhaust vent termination is less than seven (7) feet above finished grade in the area of the venting, including but not limited to decks and porches, the following requirements shall be satisfied:
1. INSTALLATION OF CARBON MONOXIDE DETECTORS. At the time of installation of the side wall horizontal vented gas fueled
equipment, the installing plumber or gas fitter shall observe that a hard wired carbon monoxide detector with an alarm and battery back-up is installed on the floor level where the gas equipment is to be installed. In addition, the installing plumber or gas fitter shall observe that a battery
operated or hard wired carbon monoxide detector with an alarm is installed on each additional level of the dwelling, building or structure served by the side wall horizontal vented gas fueled equipment. It shall be the responsibility of the property owner to secure the services of qualified licensed
professionals for the installation of hard wired carbon monoxide detectorsa. In the event that the side wall horizontally vented gas fueled equipment is installed in a crawl space or an attic, the hard wired carbon monoxide
detector with alarm and battery back-up may be installed on the next adjacent floor level.b. In the event that the requirements of this subdivision can not be met at the time of completion of installation, the owner shall have a period of
thirty (30) days to comply with the above requirements; provided, however, that during said thirty (30) day period, a battery operated carbon monox-ide detector with an alarm shall be installed.
