STEP 7
Apply high temperature sealant to 4” (102 mm) and
7” (179 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 pro-
vided and caulk around the wall plate to weatherproof.
(Fig. 20) 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” (102 mm) vent pipe however
for this method you must extend the 4” (102 mm) pipe
approximately 6” (152 mm) beyond the outer face of the
wall.

Flex Vent Pipe
NOTE: The 40” (1016 mm) flex vent is used for 90° off
the top of the unit then out the back wall.
Follow Step 1 and 2 on Page 13.
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). (Fig.
21) Measure 8” (203 mm) from the end of the pipe.
Place the next spring 8” (203 mm) from the previously
installed spring. Place the next spring approximately
8” (203 mm) from the last spring. Finally place the last
spring approximately 8” (203 mm) from the last spring
installed. (Fig. 22) Maintain equal spacing between
spacer springs.
