Installing The Fireplace Shell
The fireplace may be installed in any location that is free of air
conditioning ducts, electrical wiring and plumbing. Safety, as well as
efficiency of operation, must be considered when selecting the
fireplace location. Try to select a location that does not interfere with
room traffic, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.
The fireplace dimensions are shown below:
Installation
When installing a shelf over the top of the fireplace, the following
guidelines must be adhered to: For Rear Vent models (W3400R), the
minimum clearance from the top of the fireplace to a shelf is 7". For
Top Vent models (W3400DT), the minimum clearance is 13".
(Minimum 1" clearance must still be maintained around the vent
pipes.)

Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
W3400 fireplaces must be installed with Montigo Premium Series
direct vent components with:
5" inner dia. / 8" outer dia.
Minimum 1" clearance to combustibles required for vent pipes
Use only certifiedMontigoventcomponents.(Use of other parts will
void the Montigo warranty, and may impede the operation of the
fireplace.)
All joints must be secured with a minimum of two screws per joint
Vent terminations must not be recessed in walls or siding
Horizontal runs must be supported by a minimum of two supports
per horizontal run. A minimum of one screw on each side of
support is also required
Flex vent sections may be stretched up to 50% of their total length
(eg. a 24" section may be stretched to 36")
Maximum horizontal run for a flex section is 3 feet.
Solid vent sections may be cut less than half way from the
tapered end
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine
whether you need to use a top vent or rear vent fireplace. Figure 6,
below, shows typical fireplace locations and the venting options they
provide.
For a more detailed diagram of allowed termination locations, see
Appendix B.
Cautions:Cautions:
Cautions:Cautions:
Cautions:
Installing The Gas Line
The gas line must be installed before finishing the W3400 Fireplace.
Natural Gas requires a minimum inlet gas supply pressure of 5.5"
W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. Provision must also be made for a 1/8" N.P.T. plugged
tapping and be accessible for test gauge connection immediately
upstream of the gas supply controls to the appliance. The fireplace
gas connection and the main operating gas valve is located behind
the removable brass trim at the bottom of the unit and need only be
attached to the gas line with an approved fitting, as required by the
applicable installation codes.
Installation
Figure 6. Fireplace locations and vent terminations.
Note: After gas line is connected, each applianceconnection,
valve and valve train must be checked while under
normal operating pressure with either a liquid solution, or
leak detection device, to locate any source of leak. Tighten
any areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.
Installing The Remote Switch
The W3400's gas valve, located behind the lower brass trim, may be
connected to a wall switch or a thermostat. The valve is pre-wired and
completely self contained to generate its own power. DO NOT connect
any external power to it.
Refer to Figure 26 for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.
Figure 5. Gas line access.
During any pressure testing of the gas supply piping that excedes 1/2
psig (3.5 kPa), the appliance and its individual shutoff valve must be
disconnected from gas supply system.
When pressure testing the gas supply piping system at test pressures
of less than or equal to 1/2 psig (3.5 kPa), the appliance must be
isolated from the gas supply piping system by closing its individual
manual shutoff valve.
Vent terminations can be very hot. If the termination is less
than 7 feet above a public walkway, it should be fitted with a
certified Montigo Heat Guard. (Part no. PTKOG)
Do not obstruct, or attempt to conceal, the vent termination.
These actions will affect the operation of the fireplace, and
may be hazardous.
In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.

Model W3400T Venting Runs
For the W3400T Top Vent there are two types of installations: A)
Through-The-Wall Installations and B) Vertical (Through-The-Roof)
Installations.
A) Through-The-Wall Installations
Before you install any venting, you must determine whether the
venting run will be acceptable. Unacceptable venting can affect the
fireplace's combustion.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 7) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and
the horizontal run to the wall flange of the vent
termination is 36", this would be an acceptable
installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 90" and
the horizontal run to the wall flange of the vent
termination is 126", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace
is 78" and the horizontal run to the wall flange of the
vent termination is 108", this would NOT be an
acceptable installation.

Heat Shields
Due to high flue temperatures, heat shields are required on all W3400
installations (except those with vertical terminations) at the point where
the venting connects to the termination. With the heat shield, vent
clearances can be maintained at 1".
See Figure 8.
B. Multi-Elbow Installations
For more diffiicult installation situations, the W3400R may be installed
with 2 - 90° elbows and up to 15' of horizontal run. If using this
installation option, you must adhere to the following guidelines:
the first 90° elbow must be placed directly on the flue collar
you must have a minimum vertical lift of 50" (measured from the
hearth)
your vent run must fall within the limits set by Figure 19
Before you install any venting, you must determine whether the
venting run will be acceptable. Unacceptable venting can affect the
fireplace's combustion.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 19) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and
the horizontal run to the wall flange of the vent
termination is 36", this would be an acceptable
installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 90" and
the horizontal run to the wall flange of the vent
termination is 126", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace
is 78" and the horizontal run to the wall flange of the

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 19. Side wall clearances are 3".
Combustible surrounds may be installed with 3" clearance to the side of
the fireplace as shown in Figure 20.
Installation
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.

Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the fireplace surrounds, to select and
apply a quality Alkyd sealer prior to the applying of latex paints. This
is to prevent leaching of water from evaporation and causing a
brownish staining effect to paint over coats.

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.
Figure 19b. Combustiblesurrounds.
Fireplace Facing
When selecting the finish material for your fireplace, it is important to
remember the following: BRASS TRIMS 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.

Installing the Log Set
The W3400 is supplied with four (4) ceramic fibre logs. Logs "A"and
"B"are factory-installed on the log rest. To install the two small logs
("C"and "D"), simply place them onto their mating positions as shown
in figure 24a below. When log set is installed it should look like figure
24b.

NOTES:
If logs are not placed properly, excessive sooting will result.
If handling or vacuuming the logs, do not attempt to move
the two large logs. They are extremely fragile, and will break
easily.
The surface of the logs will crack due to the heat from the
flames. This is a normal occurance.

CAUTIONS
Fireplace gas control must be in the “OFF” position and pilot
and main burners extinguished when cleaning appliance with
a vacuum.
Doors and logs can get very hot. Handle only when cool.
General
Have the fireplace installation inspected yearly, including a visual
check of the vent system, the burner and the pilot flame. For your
convenience a 1/8" manifold pressure tap is supplied on the gas
valve for a test gauge connection. See Figure 28.
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 vapours and
liquids.
Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the

Burner Adjustment
The Wildfire is equipped with an adjustable burner, allowing you to
raise or lower the flames. To adjust the flames, locate the black knob
marked 'Hi-Lo', in the centre of the gas control valve (See Figure 27).
To raise the flame height, turn the black knob (located behind
the lower trim) counterclockwise.
To lower the flame height, turn clockwise.
Gas Control Knob
(Shown in "Pilot" postion.)
'Hi-Lo' Adjustment Knob
Figure 24. 'Hi-Lo'AdjustmentonModelW3400gasvalve. 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 biproduct of combustion) which may be visible. Film can
easily be removed by removing the door, as shown on page 13.
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 using normal
household products.
Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
Logs may be cleaned periodically with a vacuum to remove soot
or other contaminates. Do not attempt to move the 2 large logs
when cleaning. They are extremely fragile and will break easily.
WARNING:
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass
etching may cause premature glass failure.
