Step 7
Apply high temperature sealant to 4” (102 mm) and
7” (175 mm) collars or the termination one inch away
from crimped end. Guide the vent terminations 4” and
7” collars into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2” (51 mm).
Secure the termination to the wall with screws provided
and caulk around the wall plate to weatherproof. As an
alternative to screwing the termination directly to the
wall, you may also use expanding plugs or an approved
exterior construction adhesive. You may also attach the
termination with screws through the inner body into the
4” vent pipe, however for this method, you must extend
the 4” pipe approximately 6” (152 mm) beyond the outer
face of the wall.

Step 3
Install the four (4) spacer springs on the 4” flex vent
pipe. When installing the spacer springs around the 4”
pipe, stretch the spring to approximately 15” (381 mm),
wrap the spring around the pipe and interlock the ends
of the spacer spring approximately 2” (51 mm). Measure
6³⁄₄” (172 mm) from the end of the pipe. Place the next
