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:

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

Step 4
Install the unitized T-Lock vent pipe to the appliance col-
lar, following T-Lock directions on Page 14. It is not neces-
sary to seal this connection. If a 45° elbow is being used
attach the elbow to the appliance in the same manner
then attach the venting to the elbow.

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).

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.
