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 15.
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). Meas-

” (172 mm) from the end of the pipe. Place the
next spring 5” (127 mm) from the previously installed
spring. Place the next spring 6” (152 mm) from the last
spring. Finally place the last spring 12” (305 mm) from
the last spring installed. (Fig. 24)

STEP 6
Use appropriate length of
pipe sections - telescopic
or fixed - and install the
horizontal vent sections.
The sections which go
through the wall are pack-
aged with the starter kit,
and can be cut to suit if
necessary. (Fig. 22)
Sealing vent
pipe and
firestop gaps
with high tem-
perature seal-
ant will restrict
cold air being
drawn in around
fireplace.
STEP 7
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 termina-
tion to the wall with screws provided and caulk around
the wall plate to weatherproof. (Fig. 23) As an alterna-
tive 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 termi-
nation 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.
