Roof mounted Terminations
The following details are some possible configurations for
Roof mounted terminations.
Section 3-2: Installing a Roof Mounted
Direct Vent Termination (PVTK-1) for 5"/8"
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 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
8 to 8c).
„ 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 flashing and storm collars as shown.
