Please review the Installation Checklist for general
information on preparing for a successful installation of
your replace.
The replace may be installed in any location that maintains
proper clearances toair 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
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

Installing the Nailing Flange Extension
Once the replace is placed into the rough framed opening, the supplied
Nailing Flange Extension must be fasten securely into place, with nails
or wood screws.

The Supplied nailing extension must be placed along the top edge of
the replace and securely fastened in place to the non combustible
header and combustible wood framing.

Revision
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 fromthe unitthrough thetop orthrough 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 rear ue cover and gasket on the ue outlet.
• Next, Remove the Top ue collar's on the ue outlet.
• Install the (removed) rear ue cover and gasket material, to the Top
vent outlet. Fasten the cover with included hardware.
• Install the collars to the rear vent outlet using the included hardware.
Section 3-1-1: Air Baffle for H38DF &
H42DF Only
• NOTE: Air Bae is shipped open. If you are top venting, the air bae
should be closed following these steps:
Under no circumstances can Montigo ex venting be cut to
accommodate an installation. Use an alternative length to complete
your vent run.

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 8. Top Vented, wall mounted installation with 1 elbow (1 one 90° bend). The vent run
must comply with Venting Graph for Top vent, wall mounted terminations
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.

1. Frame the termination opening to 11" x 11".
2. Install exterior sheathing to the structure framing.

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 terminationto the MSRFrame usinga minimumof 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 tothe BSR Frameusing aminimum of 4screws.

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.
