The fireplace may be installed in any location that maintains proper clearances to 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.

When installing a shelf over the top of the fireplace, the
following guidelines must be adhered to: For Rear Vent
applications the minimum clearance from the top of the fireplace
to a shelf is 10" (L38) and 12" (L42). For Top Vent applications, the
minimum clearance are shown in the clearance table. (Minimum
2" clearance must still be maintained around the vent pipes.)
Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The L38DF-ST and L42DF-ST
clearance to unprotected combustible walls which are perpendicular to
the fireplace opening, must not project beyond the shaded area shown
in Fig. 24.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
the possibility of a cold-air convection current on the fireplace.

Installing The Gas Line
Vent Installation
The gas line must be installed before completing the installation of the
L38DF-ST or L42DF-ST 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 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.
This section covers the installation of direct venting and terminations.
To access the fireplace gas connection the main burner must be
removed as shown below in figure 5a.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is
allowable within applicable installation codes.

p
Use only certified Montigo vent components. (Use of other parts will void the
Montigo warranty, and may impede the operation of the fireplace.)
p
All joints must be secured with a minimum of two screws per joint
p
Vent terminations must not be recessed in walls or siding
p
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
p
Flex vent sections may be stretched up to 50% of their total length (eg. a
24" section may be stretched to 36")
p

Note: After gas line is connected, each appliance connection,
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.
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.
Use Montigo VSS Vinyl Heat Shield when using on
applications with vinyl siding to guard against possible
damage.
Installing The Remote Switch
The L38DF-ST and L42DF-ST's gas valve, located behind the lower
trim, may be connected to a wall switch. The valve generates its own
power on a millivolt circuit. Use only low voltage wire, and DO NOT
connect any external power to it.
Note: The switch location must not exceed 30' from the fireplace.

Heat Shields
Due to high flue temperatures, the heat shield (RHS101) must be
used on all installations straight through the wall, at the point
where the vent pipe connects to the termination. With the heat shield,
vent clearances can be maintained at 1". The heat shield is not
included with the fireplace.
To install the heat shield, slide one section over the vent pipe on the
inside of the wall opening, with the circular portion inside the wall
cavity. Screw the shield in place over the wall opening. Install the
second section on the outside of the wall opening sliding the circular
portion into the wall opening. Refer to Figure 8.

Long Vent Runs:
For longer or more complex vent runs, vertical lift is required. First
ensure that the planned run is acceptable using the Vent Graph. Plan
out the required components using the chart above. You may be able
to use fewer components using the chart below.
Example:
A 10' section of rigid pipe and a 90° elbow may be used in conjunction with a 3 ft. flex section (PFL-3) will, when extended in a chase,
allow for a maximum horizontal run of twelve and one-half feet from
the centre of the fireplace to outside wall and a minimum of 7'6" when
retracted in opposite direction. (See Figure 9.)

Reduced Vertical Installation
It is possible to reduce vertical vent runs from 5"/8" venting to 4"/7"
venting. Reduced vertical venting may only be used when the installation
exceeds 12 feet and terminates through the roof, and if the vertical vent
reducer is used with the following venting configuration.
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.
Warning:
When covering the upper metal portion of the fireplace with a noncombustible material Please Note: The decorative facing materials
may be subject to temperatures in excess of 250° F. This should be
considered when selecting facing materials.
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.
Figure 18. Reducing Vertical Vent from 5/8" to 4/7".
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 24. Side wall clearances are 3".
Combustible surrounds may be installed with 3" clearance to the side
of the fireplace as shown in Figure 25.
Fireplace Facing
When selecting the finish material for your fireplace, it is important to
remember the following: THE HORIZONTAL LOUVRES 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.
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.

General
See pages 11 to 15.
Have the fireplace and installation inspected yearly. The inspection
must include, but is not limited to, the following:
p
• A visual check of the entire vent system and termination.
Burner Adjustment
• An inspection of the explosion relief flappers and the door gasketing to ensure a proper seal.
The L-Series DF 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 32).
The front burners are not adjustable.
p
p
• An inspection of the burner, venturi, and primary air openings.
To raise the flame height, turn the black knob (located behind the
lower trim) counter-clockwise.
• 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. See Figure 32.
To lower the flame height, turn clockwise.
• Inspection of all optional equipment; fans, thermostats, etc.
'Hi-Lo' Adjustment Knob
For Natural Gas this appliance requires a minimum inlet pressure
of 5.5" W.C. and a manifold pressure of 3.5" W.C.
p
For Propane Gas this appliance requires a minimum inlet pressure
of 11" W.C. and a manifold pressure of 10" W.C.
p
Always keep the fireplace area clear and free of combustible materials,
as well as gasoline and other flammable vapors and liquids.
p
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.
p
Figure 32. 'Hi-Lo' Adjustment on the L-Series DF's gas valve.
Note: L-Series DF-I models (electronic ignition) do not
feature hi/lo adjustment.
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.
p
p
CAUTIONS
p
p
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.
p
p
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 12.
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. Linear Burners may be cleaned periodically with a vacuum to remove
soot or other contaminates.
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.
