Installation
Installing and Framing the Fireplace
The replace may be installed in any location that maintains proper clear-
ances to air conditioning ducts, electrical wiring and plumbing. Safety,
as well as efciency of operation, must be considered when selecting
the replace location. Try to select a location that does not interfere
with room trafc, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.
The replace dimensions are shown below:
When installing a shelf over the top of the replace, the following
guidelines must be adhered to: For Rear Vent applications the
minimum clearance from the top of the replace to a shelf is 6 1/2". For
Top Vent applications, the minimum clearance is 13 1/2". (Minimum
2" clearance must still be maintained around the vent pipes.)

** Refer to graph and requirements on Page 11.
Unprotected combustible walls which are perpendicular to the replace
opening, must not project beyond the shaded area shown in Figure 25.
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 replace.

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 replace. Figure 6, below, shows
typical replace locations and the venting options they provide.
For a more detailed diagram of allowed termination locations, see Ap-
pendix A.
Figure 6. Fireplace locations and vent terminations.
Installing The Gas Line
The gas line must be installed before nishing the C-SeriesDV 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 replace 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 tting, as required by the applicable installation codes.
• 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.
Note: After gas line is connected, each appliance connection,
valveandvalvetrainmustbe checkedwhileundernormal
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.
Figure 5. Gas line access.
The appliance and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
Q C-Series DV fireplaces are certified for use with Montigo Premium Series
(5"/8") venting components. The C-Series DV Top Vent may be used with
the Montigo Standard Series (4"/7") components on vertical vent runs only.
QMinimum 1" clearance to combustibles around the vent pipe.
QUse only certified Montigo vent components.(Use of other parts will void
the Montigo warranty, and may impede the operation of the fireplace.)
CAUTIONS!
 Vent terminations can be very hot. If the termination is less than 7 feet
above a public walkway, it should be tted with a certied Montigo
Heat Guard. (Part no. PTKOG).
 Do not obstruct, or attempt to conceal the vent termination.
These actions will affect the operation of the replace, and may
be hazardous.
 In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.
 Use Montigo Vinyl Heat Shield (Part no. VSS) when using on
applications with vinyl siding to guard against possible damage.

1. Ensure that the two long mounting brackets are facing the bottom
of the termination. (See inset). This will provide more heat protection
at the top of the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal
screws.
Installing Heat Guards over Terminations
Installing The Remote Switch
The C-Series DV's gas valve, located behind the lower trim, may be
connected to a wall switch. The valve will either generates its own power
on a millivolt circuit or draws its power from an AC connection inside
the replace, depending on the model of your unit. Use only low voltage
wire, and DO NOT connect any external power to the remote switch.
Refer to Figures 26 & 27 for wiring requirements.
Note: The switch location must not exceed 30' from the replace.
Heat Shields
Due to high ue temperatures, heat shields are required on all C Series
DV 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”.
Figure 8. Heat Shield. Install by sliding over the vent pipe where it

Installation
Top Vent Venting Runs
For the C-Series DV 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 replace's
combustion.
The Venting Graph
Measure the vertical height from the replace hearth to the centre of
the termination and the horizontal run from the from the replace ue
collar to the wall ange of the termination. Plot on the Venting Graph
(Fig. 9) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
C-Series DV
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 30", this would be an acceptable
installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal run to
the wall flange of the vent termination is 120", this would be an accept-
able installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 72" and the
horizontal run to the wall flange of the vent termination is 84", this would
NOT be an acceptable installation.

Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 60" and
the horizontal run to the wall ange of the vent termination is 108",
this would NOT be an acceptable installation.
B. Multi-Elbow Installations
For more difcult installation situations, the C-Series DR Rear Vent may
be installed with two - 90° elbows and up to 15' of horizontal run. If using
this installation option, you must adhere to the following guidelines:
Important: Some models are not available to be installed in a rear
vent application. Please refer to the model specications on page
2 of this manual.
 the rst 90° elbow must be placed directly on the ue 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 22.
Before you install any venting, you must determine whether the venting
run will be acceptable. Unacceptable venting can affect the replace's
combustion.
The Venting Graph
Measure the vertical height from the replace hearth to the centre of
the termination and the horizontal run from the from the replace ue
collar to the wall ange of the termination. Plot on the Venting Graph
(Fig. 22) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Figure 22. C-Series DV Multi-Elbow Venting Graph.
Figure 23. Multi-elbow installation. Distance 'H' must be a minimum of
of 50". The vent run must comply with figure 22.
NOTES: All dimension lengths for vertical or horizontal runs are
measured from center of the vent pipe.
Venting runs must fall within the limits set by the venting
graph (see Figure 22).

Installation
Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over the
top and on the front of the replace provided that they do not project
beyond shaded area shown in Figure's 24 & 24a.
Side wall clearances are 3". Combustible surrounds may be installed
with 3" clearance to the side of the replace as shown in Figure 25.
Fireplace Facing
When selecting the nish material for your replace, 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 replace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the replace opening at all, because it will interfere with
the access to retainers for removal of glass door.
Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for re 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
replaces which are hot, fuel and energy efcient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above replace may be hot to touch.
Warning:
When covering the upper metal portion of the replace with a non-
combustible 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.
Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the replace 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.

Do not clean glass with abrasive materials as any glass
etching may cause premature glass failure.
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 replace 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 appers and the door
gasketing to ensure a proper seal.
• An inspection of the burner, venturi, and primary air openings.
• An inspection of the gas valve, gas components, and pilot ame.
For your convenience a 1/8" manifold pressure tap is supplied
on the gas valve for a test gauge connection. See Figure 31 &
32.
• Ensure proper log placement as per this manual.
• 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 replace area clear and free of combustible materials,
as well as gasoline and other ammable vapors and liquids.
■ Do not use this appliance if any part has been under water. Immediately
call a qualied 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 pages 17 to 19.
Burner Adjustment
The C-Series DV is equipped with an adjustable burner, allowing you
to raise or lower the ames. To adjust the ames, locate the black knob
marked 'Hi-Lo', in the right of the gas control valve (See Figure 31). The
front burners are not adjustable.
■ To raise the ame height, turn the black knob (located behind the
lower trim) counter-clockwise.
■ To lower the ame height, turn clockwise.
Figure 31. 'Hi-Lo' Adjustment on the C-Series DV's gas valve.
Cleaning
When the replace is rst activated, there may be some smoking and
a visible lm 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 lm (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
15. 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 ring 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 rebox free from dust and lint.
■ Logs may be cleaned periodically with a vacuum to remove soot or
other contaminates.
Note: C-Series DV-I models (electronic ignition) do not feature
hi/lo adjustment.
