venting. Do not use silicone sealant at the inner fl ue
exhaust connections.
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. Figure 11 (For com-
bustible walls fi rst frame in opening.)
Combustible Walls: Cut a 10
mm) hole through the exterior wall and frame as shown.
Figure 11
Noncombustible Walls: Hole opening must be 8

(X) required from the base of the fl ue collars to the center
of the wall opening. Figure 12
Step 4
Using appropriate length of pipe section(s) attach to fi re-
place with three (3) screws. Follow with the installation of
the elbow.
Step 5
Measure the horizontal length requirement fi guring a 1
(32 mm) overlap, i.e. from the elbow to the outside wall
cap. Figure 13

Requirement
Always install horizontal venting on a level
plane.
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 of 1
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.
