on preparing for a successful
installation of your replace.
The replace may be installed
in any location that maintains
proper clearances to air
conditioning ducts, electrical
wiring and plumbing. Safety, as
well as eciency of operation,
should be considered when
selecting the replace location.
Select a location that does not
interfere with room trac, has
adequate ventilation and oers
an accessible path for Direct
Vent installation.

Figure 4. Combustible Wall Clearances
When installing a shelf over the top of the replaces, the following
guidelines must be adhered to:
For Rear Vent applications, the minimum clearance is 1" from the rear of
the replace to a wall, or any combustible materials, and 11" clearance
from the top of the replace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 1" from the rear
of the replace to a wall, or any combustible materials, and 17 1/2" to
the underside of any combustible shelf materials.
1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.
† Note: Clearance from top of replace to a ceiling within the replace
enclosure.
** Note: For mantel clearance, please refer to Section 6: Finishing
The 4" nailing ange extension is shipped attached to the top edge of
the replace, see Figure 1.
The nailing ange extension may be substituted with a piece of
NON-Combustible material of the same thermal characteristics, ie:
cement board or equivalent to t the opening. This is recommended
in applications where the facing materials will not adhere to the metal
nailing ange. To remove the Nailing Flange Extension follow the
directions below:
To avoid elevated mantel temperatures, all H-Series gas replaces
are required to have the supplied standos installed. The replace is
supplied with two standos. Bend and install these standos on top
of the replace ensuring that the height of the stando maintains a
8" clearance.
Figure 4.b Installing standos
STEP 1: Remove screws from top of the unit
STEP 2: Remove shell from the top of unit. Remove screws from
outer edge.
STEP 4: Remove the nailing flange extension from the unit.
Reinstall shell. Screw shell in place.

Section 3: Venting
Montigo supplies a variety of direct venting and termination options.
The direct vent termination location MUST be selected such that it is the
highest point in the venting assembly. It should also be selected such
that it provides the shortest vent run possible. Should it be impossible
to ensure that the termination is the highest point or to meet the
venting guidelines laid out below please contact your Montigo dealer
to discuss power venting options.
Notes For Planning Venting:
• Ventingcan originate from the unit through thetop or through the rear
• Venting can terminate through the roof or through an exterior wall.
• Refer to Appendix A - Termination Locations to ensure the planned
termination location is acceptable.
• Once the termination location has been established, refer to the
appropriate section below for installation details
• All replaces shipped from the factory are top vent.
• Silicone application is NOT required when joining Montigo vent
pipes and components.
Section3-1:Convertingtop/rearvent
Use the following instructions to convert a unit for side vent use:
• Remove the Side ue cover and gasket (5" and 8") on the ue outlet,
as shown in Figure 5.
• Next, Remove the Top ue collar's (5" and 8") on the ue outlet, as
shown in Figure 5.
• Install the (removed) Side ue cover and gasket material, to the Top
vent outlet. Fasten the cover with included hardware, as illustrated
Figure 5b.
• Install the (5" and 8") collars to the Side vent outlet using the included
hardware, as illustrated Figure 5b.

Roof mounted terminations
The following details are some possible congurations for roof mounted
terminations. See below.
This section applies to installations where the direct vent termination
will be roof mounted.
Section 3-2-1: Venting Layout
Selection of components and details of venting lay out should adhere
to the following guidelines:
• The maximum termination point is 32’ above the replace (NOTE:
if the maximum termination height is used, the ame pattern may
be aected).
• The Vertical termination must be a minimum 2’ higher than where
the termination exits the roong materials, (asphalt shingles, cedar
shakes, etc). This distance should be measured from the high side of
the roof slope where the ue ashing intersects the roong materials.
(see Figures 8 to 8c).
• See Appendix A for termination locations.
• For a more detailed diagram of allowed termination locations, see
Appendix A.
• A maximum of two osets (each oset is made up of 2-90° bends)
may be made for vertical vent runs.
• Firestops must be installed as required by National & local codes.
• Ensure all horizontal runs are supported with a minimum of 3
supports per 10’ of venting.
• Install all roof ashing and storm collars as shown.
Figure 6. Top vent, roof mounted termination with no oset in vent run.

Installationofterminationwithbuiltinframe
A termination with a built-in frame is installed during framing of a
structure.
1. Frame the termination opening to 11" x 11".
2. Install exterior sheathing to the structure framing.
3. Fasten the termination to the sheathing using a minimum of 4 screws.

The VSS Termination shield is installed when the exterior of a structure
is clad with Vinyl siding. It is placed directly above, and on-center with
the termination.
Installation of termination frame at time of framing
Terminations with a MSR frame allow the installation of the frame prior
to installation of the termination.
1. Frame the termination opening to 12" x 12".
2. Secure the MSR Frame to the exterior sheathing of the structure.
3. Fastenthe termination to the MSRFrameusing a minimum of 4screws.
1. Frame the MOSR opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs, concrete,
or nished wall construction using a minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, (from
the inside) and attach to the MOSR by installing a min. quantity of 4
bolts into the threaded nuts on the MOSR Frame.
Installation of termination frame at time of framing in masonry
Terminations with a BSR frame allow the installation of the frame in
masonry prior to the installation of the termination
1. Frame the BSR opening to 12" x 12".
2. Secure the BSR Frame to the exterior sheathing of the structure.
3. Fastenthe termination to the BSR Frame using a minimum of 4 screws.

Installing heat guards
Installing heat guards overterminations is recommended ininstallations
where the termination is located within 7' feet above grade, or above
a pedestrian walkway, and may be required by code in public areas.
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.

ExampleA:(AcceptableInstallation)
If the vertical dimension from the hearth is 114" and the horizontal
run to the wall ange of the vent termination is 126", this would be an
acceptable installation.
ExampleB:(UnacceptableInstallation)
If the vertical dimension from the hearth is 66" and the horizontal run
to the wall ange 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 72" and the
horizontal run to the wall ange of the vent termination is 144", this
would not be an acceptable installation.
PRC Rear 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 with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.

Selection of components and details of venting layout should adhere
to the following guidelines:
• Vent terminations must not be recessed in walls or siding.
• For Heat Shield requirements see Section 3-3.
• Once the proposed venting layout has been determined refer to
graph to ensure the layout is acceptable.
Notes Wall Mounted Terminations: TOP VENT
• All measurements 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.
Corner Top 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

If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
