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 10 - 10c
).
For a detailed diagram of allowed termination locations, see
Appendix A.
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.
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 flashing and storm collars as shown.
