FIGURE 5 - Attaching
Double-Wall (Type B)
Pipe to a Vent Cap
FIGURE 5 - STEP 1
Place a continual 3/8” bead
of silicone sealant around
the circumference of the
vent cap collar. This will
prevent any water inside
the vent cap from running
down the double-wall pipe.
Do STEP 2 immediately
following STEP 1.
FIGURE 5 - STEP 2
Secure the vent cap to the
double wall pipe by drilling
and inserting a 3/4” long
sheetmetal screw into the
vent cap collar. Do not over
tighten screw.
Insert the collar on the vent
cap inside the inner wall of
the double-wall pipe. Insert
as far as possible. Add ad-
ditional silicone sealant to
fully close any gaps be-
tween the vent cap and the
double wall pipe. This is
necessary to prevent water
from entering the double
wall pipe.
