VERTICAL SIDEWALL INSTALLATION
NOTE: Sealant is not required to assemble fireplace
venting. Do not use silicone sealant at the inner flue
exhaust connections.
Step 1
Locate vent opening on the wall. It may be necessary to
first position the fireplace and measure to obtain hole lo
-
cation. Depending on whether the wall is combustible or
noncombustible, cut opening to size.

bustible walls first frame in opening.)

Step 3
Place fireplace into position. Measure the vertical height
(X) required from the base of the flue collars to the center
of the wall opening.

Sealing vent pipe and firestop gaps with high tem

perature sealant will restrict cold air being drawn in
around fireplace.
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
⁄
4
" (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.
Support horizontal pipes every 36" (914
mm) with metal pipe straps.
