Section 2: Framing
1). Frame in the enclosure for the unit with framing materials. The
framed opening for the assembled H*38DF* replace is 37 3/4" wide,
x 42" high x 21⅛" deep. For assembled HW38DF* replace is 37 3/4"
wide, x 42" high x 22⅛" deep , see Figure 2 .
NOTE: When constructing the framed opening, please ensure there is
access to install the gas line when the unit is installed. See Figure 23.
* When sheetrock is not used behind
the replace, framing depth "O" may be
reduced by 5/8".

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 2" from the rear
of the replace to a wall, or any combustible materials, and 9" clearance
from the top of the replace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 2" 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, Figure 4.
For Top or Rear Vent applications where the Minimum height is required
above the replace, (for an alcove or low prole shelf), ALL Materials
MUST BE NON-COMBUSTIBLE, Figure 5. The minimum clearance is
2" from the rear of the replace to a wall, or any combustible materials.
1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.
The replace clearances are shown below:

Installing The Standoffs
To avoid elevated mantel temperatures, all H*38DF* 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 6. Installing the standoff's.
Figure 7. Installing the Nailing Flange Extension.
Installing the Nailing Flange Extension
Once the replace is placed into the rough framed opening, the supplied
Nailing Flange Extension (Part No. H38074) must be fasten securely
into place, with nails or wood screws. as shown in Figure 7.
Note: The nailing ange extension can be substituted with a piece of
NON-Combustiblematerial of the same size and thermal characteristics,
ie: cement board or equivalent. This is recommended in applications
where the facing materials will not adhere to the metal nailing ange.

Section 3-1: Converting to Rear Vent
Use the following instructions to convert an H*38DF* for Rear Vent use:
1. Remove the Rear ue cover and gasket (5" and 8") on the ue
outlet, as shown in Figure 8.
2. Next, Remove the Top ue collar's (5" and 8") on the ue outlet,
as shown in Figure 8.
3. Install the (removed) Rear ue cover and gasket material, to the
Top vent outlet. Fasten the cover with included hardware, as
illustrated Figure 8a.
4. Install the (5" and 8") collars to the rear vent outlet using the
included hardware, as illustrated Figure 8a.

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:
Ventingoriginates from the unitthroughthetop or through therear
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.
NOTE: Air Bafe is shipped open. If you are top venting, the air bafe
should be closed following these steps:
Section 3-1-2: Air Bafe for H38DF* & HR38DF* Only

closed.

Note: Images are shown without screens for clarity purposes. However,
your replace should not be operated without proper installation of
screens.

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 affected).
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 9 to 9c).
Termination location must be a minimum 6’ from a mechanical
air inlet.
For a more detailed diagram of allowed termination locations,
see Appendix A. .
A maximum of two offsets (each offset 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.
