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 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.

TERMINATION (PVTK-1)
This section applies to installations where the direct vent termi-
nation 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, (asphault 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 11 to 11c *).
Termination location must be a minimum 6’ from a mechanical
air inlet.
Termination location must be a minimum 18” from a parapet wall.
A maximum of two offsets (each offset is made up of 2-90°
bends) may be made.
Install a restop at any location where venting passes through
combustible materials and construction.
Utilize support straps, or support plates, and rings (as required)
to meet acceptable building practices.
Install all roof ashing and storm collars as shown.
