Sealing vent pipe and firestop gaps with high tem-
perature sealant will restrict cold air being drawn in
around fireplace.
Step 7
Apply high temperature sealant to 4” (102 mm) and
7” (178 mm) collars or the termination one inch away
from crimped end. Guide the vent terminations 4” and
7” collard 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.
Support horizontal pipes every 36”
(914mm) with metal pipe straps.

Vertical Sidewall Installation
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 19.
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. 23) Measure from8” (203 mm) 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. 24) Maintain equal spacing between
spacer springs.
Step 4
Install the 4” (102 mm) flex vent pipe to the appliance
collar as described on Page 14. Secure the end with
the first spring 8” (203 mm) from the flex pipe end to the
unit.
Step 5
Slide the 7” (178 mm) flex vent pipe over the 4” flex
vent pipe and secure the 7” collar as described on Page
14.
