vent collars if a smaller vent pipe than the fi replace
starting collars is to be used in the vent system.
Adaptors are also used to connect the last smaller
vent system component to the Power Vent cap. SEE
TABLE 1 FOR ADAPTOR DESCRIPTIONS.
4. After determining the location of the vent system
termination point (see Step 1) cut a 10 in. X 10 in.
(for 4 in./6 in. diameter pipe) or a 10 in. X 12 in. (for 5
in./8 in. diameter pipe) square hole through the wall
or roof. Apply the adhesive back fi berglass tape to
the last vent system component 1-1/4 in. from the
edge. Firmly press the tape on to the venting and
fold the extra tape inside the venting. See Figure
