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. 7)
For combustible walls first frame in opening.
Combustible Walls
(Fig. 7): Cut a 9

” and attach to firestop
with #8 sheet metal screws (supplied). Assemble sleeve and
attach to firestop with #8 sheet metal screws (supplied). Install

STEP 4
Measure the horizontal length requirement including a ”
(51 mm) overlap, i.e. from the elbow to the outside wall
finish plus ”, or the distance required if installing a second
90° elbow. (Fig. 30)
STEP 5
Use appropriate length of pipe section - telescopic or fixed
- and install the horizontal vent sections. The 0” (508
mm) section of pipe which goes through the wall is pack-
aged with the 7TDVSK starter kit, and can be cut to suit if
necessary. (Fig. 31)
Sealing vent pipe and firestop gaps with high
temperature sealant will restrict cold air being
drawn in around fireplace.
