Clearances

When installing a shelf over the top of the replaces, the following
guidelines must be adhered to:

For Side Vent applications, the minimum clearance is 2" from the Side
of the replace to a wall and 12" 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 Side
of the replace to a wall and 19" 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.

and combustible wood framing.

Note: The nailing ange extension can be substituted with a piece of
NON-Combustible material 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.

† Note: Clearance from top of replace to a combustible ceiling within
the replace enclosure.

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
should it be impossible to meet the venting guidelines laid out below
please contact your Montigo dealer to discuss power venting options.

NOTES FOR PLANNING VENTING:

 Venting originates from the unit through the top or through

the side

 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.

1. Remove the Side ue cover and gasket (5" and 8") on the ue
outlet, as shown in Figure 7.

2. Next, Remove the Top ue collar's (5" and 8") on the ue outlet,
as shown in Figure 7.

3. Install the (removed) Side ue cover and gasket material, to the

Section 3-2: INSTALLING A ROOF MOUNTED DIRECT VENT

TERMINATION (PVTK-1)
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 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 8 to 8c).

 Termination location must be a minimum 6’ from a mechanical

air inlet.

 Termination location must be a minimum 18” from a parapet wall.
 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.

 Firestops must be installed as required by National & local codes.
 Ensure all runs are supported with a minimum of 3 supports

per 10’ of venting.

 Install all roof ashing and storm collars as shown.
