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” (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.
Support horizontal pipes every 3’ (91 cm) 
with metal pipe straps.

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 17.
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

horizontal pipe measure 6¹⁄₂” (165 mm) from the top of 
the unit immediately after the 90° formation. (Fig. 36) 
Be sure to follow the 1” (25 mm) rise in a 24” (610 mm) 
horizontal run rule.
