LDVR Series Direct Vent Gas Fireplace
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. 25)
For combustible walls first frame in opening.
Combustible Walls (Fig. 25): Cut a 9³⁄₈"H x 9³⁄₈" W
(240 x 240mm) hole through the exterior wall and
frame.
Noncombustible Walls (Fig. 25): Hole opening must
be 7.5" (190mm) in diameter.

clearance sleeve parts to proper length (MAXIMUM
12"/305mm). (Fig. 26) Adjust sleeve to minimum (9³⁄₈" x

sembly.
Zero clearance sleeve is only required for
combustible walls.
STEP 3
Apply a bead of high temperature sealant to the inner
and outer flue collars of the fireplace and using ap-
propriate venting component(s) attach to fireplace with
three (3) screws. (Fig. 27) Follow with the installation
of the inner and outer elbow. Again secure joints with
three (3) sheet metal screws. Wipe off any excess high
temperature sealant.

STEP 4
Measure the horizontal length requirement including a
2" (50mm) 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)
STEP 5
Use appropriate length of pipe section - telescopic or
fixed - and install the horizontal vent sections. The 20"
(508mm) section of pipe which goes through the wall is
packaged with the 7TDVSK starter kit, and can be cut
to suit if necessary. (Fig. 29)
Sealing vent pipe and firestop gaps with
high temperature sealant will restrict cold
air being drawn in around fireplace.
