VENTING INSTALLATION
VERTICAL SIDEWALL INSTALLATION -
TWIST LOCK PIPE
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. Figure 16 (For com-
bustible walls first frame in opening.)
NOTE: When using flex vent, the opening will have to be
measured according to the 1/2" (13 mm) rise in 12" (305
mm) vent run.
Combustible Walls: Cut a 95/8"H x 95/8"W (244 x 244
mm) hole through the exterior wall and frame as shown.
Figure 16
Noncombustible Walls: Hole opening must be 71/2"
(191 mm) in diameter.

Step 4
Using appropriate length of pipe section(s) attach to fire-
place with three (3) screws. Follow with the installation of
the inner and outer elbow, again secure joints with three
(3) sheet metal screws.
Step 5
Measure the horizontal length requirement including a 2"
(51 mm) overlap, i.e. from the elbow to the outside wall
face plus 2" (51 mm) (or the distance required if installing
a second 90° elbow). Figure 18
Always install horizontal venting on a level
plane.

Step 6
Use appropriate length of pipe sections - telescopic or
fixed - and install. The sections which go through the wall
are packaged with the starter kit, and can be cut to suit if
necessary.
