VENTING INSTALLATION
VERTICAL SIDEWALL INSTALLATION
Step 1
Locate vent opening on the wall. It may be necessary to
fi
rst position the
fi
replace and measure to obtain hole lo-
cation. Depending on whether the wall is combustible or
noncombustible, cut opening to size.

(X) required from the base of the
fl
ue collars to the center
of the wall opening.

Step 6
Use appropriate length of pipe sections — telescopic or
fi
xed — and install.
Sealing vent pipe and fi restop gaps with high tem-
perature sealant will restrict cold air being drawn in
around fi replace.
Step 7
Guide the vent terminations 5" and 8" collard into their
respective vent pipes. Double check that the vent pipes
overlap the collars by a minimum 1
1
⁄

" (32 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.
Always install horizontal venting on a level
plane.
Support horizontal pipes every 36" (914 mm)
with metal pipe straps.
