Section 3-2:
INSTALLING A ROOF MOUNTED DIRECT 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 fireplace (NOTE:
if the maximum termination height is used, the flame pattern
may be affected).
The Vertical termination must be a minimum 2’ higher than
where the termination exits the roofing materials, (asphalt
shingles, cedar shakes, etc)�
This distance should be measured
from the high side of the roof slope where the flue flashing
intersects the roofing materials. (see
Figures 9 - 9c
).
For a detailed diagram of allowed termination locations, see
Appendix A�
Termination location must be a minimum 6’ from a mechanical
air inlet.
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 flashing and storm collars as shown.
