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 28
(For com-
bustible walls first frame in opening.)
Note:
When using flex vent, the opening will have to be
measured according to the 1/” (13 mm) rise in 1” (305
mm) vent run.

Step 5
Measure the horizontal length requirement including a ”
(51 mm) overlap, i.e. from the elbow to the outside wall
face plus ” (51 mm) (or the distance required if installing
a second 90° elbow).
Figure 30
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.
