Vertical Terminations - Rigid Pipe 4" x 6-5/8" (102mm x 168mm)
The minimum components required for a basic vertical termination are:
1 Vertical Termination Cap
1 Rigid Pipe Adaptor (510-994)
1 Ceiling Firestop
1 Flashing
1 Storm Collar
1 Length of pipe to suit wall thickness
(see chart)
When using Rigid Vent other than
Simpson Dura-Vent, 3 screws must be
used to secure rigid pipe to adaptor.
Galvanized pipe is desirable above the roofline due to its higher
corrosion resistance. Continue to add pipe sections through the
flashing until the height of the vent cap meets the minimum height
requirements specified in table below or local codes. Note that
for steep roof pitches, the vertical height must be increased. A
poor draft, or down drafting can result from high wind conditions
near big trees or adjoining roof lines, in these cases, increasing
the vent height may solve the problem.
