Installation
Installing The Fireplace Shell
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 9". For
Top Vent applications, the minimum clearance is 17 1/2". (Minimum
2" clearance must still be maintained around the vent pipes.)

Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
■ H34DF fireplaces are certified for use with Montigo Standard Series (4" /
7") venting components.
■ H42DF& H38DF fireplaces are certified for usewith MontigoStandard Series
(5" / 8") venting components.
■Minimum clearance to combustible construction around the vent pipe
is 1" on all sides, except on horizontal venting where the top of the pipe
must have a clearance of at least 2".
■Use only certified Montigo vent components. (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
■Horizontalrunsmustbesupportedbyaminimumoftwosupportsperhorizontal
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 with no vertical rise is 6 feet.
■Flex vent sections over 6 feet must fall within the limits set by the venting
graph and must have a minimum vertical rise of 3 inches per foot of flex.
■Solid vent sections may be cut less than half way from the female end
■Venting components can be used in any combination of solid/rigid pipe or flex
pipe and in any orientation (Male connectors can face in any direction)
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 6a, below, shows
typical replace locations and the venting options they provide.
For a more detailed diagram of allowed termination locations, see Ap-
pendix A.
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. MTKOG/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.
Figure 6a. Fireplace locations and vent terminations.
Installing The Gas Line
The gas line must be installed before nishing the H-Series DF 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.
To access the replace gas connection the main burner must be
removed as shown below in gure 5b.
• 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,
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.
Figure 5a. 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).

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 H-Series DF'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.
Refer to Figure 26 for wiring requirements.
Note: The switch location must not exceed 30' from the replace.
Installing The Standoffs
To avoid elevated mantel temperatures, all H-Series DF gas
replaces are required to have the supplied standoffs installed.
The replace is supplied with two standoffs. Bend and install these
standoffs on top of the replace ensuring that the height of the standoff
maintains a 6" clearance.
Figure 6b. Installing the standoff's.
Installing the Nailing Flange
Extension H38DF H42DF
Once the replace is placed into the framed opening, the supplied

Installation
Top Vent Venting Runs
For the H-series DF 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 replace ue collar to
the wall ange of the termination. Plot on the Venting Graph (Fig. 9a)
with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
H34DF
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal run to
the wall flange of the vent termination is 180", this would be an accept-
able installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 48" and the horizontal run to
the wall flange of the vent termination is 72", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 60" and the hori-
zontal run to the wall flange of the vent termination is 144", this would
NOT be an acceptable installation.
Figure 9a. H34DF Top Vent Venting Graph
H38DF
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 74" and the
horizontal run to the wall flange of the vent termination is 108", this would
NOT be an acceptable installation.
Figure 9b. H38DF Top Vent Venting Graph
H42DF
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 108" and the horizontal run to
the wall flange of the vent termination is 120", this would be an acceptable
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 2:
Rigid sections and an elbow used in conjunction with 3 ft. ex section
(MFL-3 / PFL-3) will, when extended in a ve foot chase, allow for a
maximum horizontal run of twelve and one-half feet from the centre of
the replace to outside wall and a minimum of 7'6" when retracted in
opposite direction (see Figure 12 and 13).
"C" ex sections and "D" rigid sections may be used in conjunction with
one another to obtain different possible horizontal length installations.
NOTE: Flex section with no vertical rise must not exceed maximum
horizontal length of 3 feet (see Figure 14). Flex runs over 3 feet must
fall within the limits set by the venting graph, and must have a minimum
vertical rise of 3" per foot of ex.
Important:
An inspection of the explosion relief appers and door must be
made prior to lighting the replace. This will ensure the door gas-
keting material will provide an adequate seal during operation.

PFL-2 (12" or 24" compressed length) and a frame, if appropriate.
Flex may be turned to obtain desired degree of angle required but
must not exceed 45°.
Figure 19. Extended installation.
Rear Vent Venting Runs
The H-Series DF Rear Vent has three possible installations which do
not require vertical lift, all of these installations require that you install
the RHS101 heat shield.
Heat Shield
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, proper vent clearances can be
maintained. The heat shield is not included with the replace.
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 19.
Figure 19. Heat Shield. Install by sliding over the vent pipe where it
passes through combustible construction.
Note: Through the wall venting kits are also available for both
the Straight and the Corner Installation. The Kit includes a heat
sheild, a PFL-18 (f/f) exible pipe, and a termination with or without
a mounting frame.
1. Straight Installation.
The height from the hearth to the center of the termination is 21
3/4". For straight installations use a 12" extension pipe (PXT-12)
with female/female connections. For shorter installations, cut the
PXT-12 to the desired length. Refer to gure 19a.
Ensure that the RHS101 heat shield is installed before attaching
the pipe to the termination.
Note: For Rear Vent models, maximum horizontal run with no
vertical lift must never exceed 12".

B. Multi-Elbow Installations
For more difcult installation situations, the H-Series DF 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:
 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 22a
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 replace ue collar to
the wall ange of the termination. Plot on the Venting Graph (Fig. 22a)
with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
H34DF
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and the horizontal
run to the wall ange of the vent termination is 36", this would be
an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 94" and the horizontal
run to the wall ange of the vent termination is 126", this would be

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 24. Side wall clearances are 3".
Combustible surrounds may be installed with 3" clearance to the side
of the replace as shown in Figure 25.
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.

Fireplace Facing
When selecting the nish material for your replace, it is important to
remember the following:
If the surround of the replace is to be painted to match the room decor,
heat-resistant paint must be provided . Also, 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 and access to the lower
compartment.

Warning:
When covering the upper metal portion of the replace, up to 6" (as
shown, Fig.24& Fig.25) 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.
