Vertical Sidewall Installation
STEP 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 26)
For combustible walls first frame in opening.
Combustible Walls (Fig. 26): Cut a 9³⁄₈"H x 9³⁄₈" W
(240 x 240 mm) hole through the exterior wall and
frame.
Noncombustible Walls (Fig. 26): Hole opening must
be 7.5" (190 mm) in diameter.

STEP 3
Measure the horizontal length requirement including a
2" (51 mm) overlap, i.e. from the elbow to the outside
wall finish plus 2", or the distance required if installing a
second 90° elbow. (Fig. 28)
Always install hori-
zontal venting on a
level plane.

Use appropriate length of pipe section - telescopic or
fixed - and install the horizontal vent sections. A starter
section of pipe which goes through the wall is packaged
with the 7TCRVT kit, and can be cut to suit if necessary.
(Fig. 29)
Sealing between the vent pipe and firestop
with high temperature sealant will restrict
cold air being drawn in around fireplace.
