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 240 mm) hole through the exterior wall and frame.

Noncombustible Walls (Fig. 25): Hole opening must be 7.5” (190 mm) in diameter.

STEP 2

Measure wall thickness and cut adjustable zero clearance sleeve parts to proper length (MAXIMUM 12”/305 mm). (Fig. 26) Adjust sleeve to minimum (9³⁄₈” x 9³⁄₈” and attach to firestop with #8 sheet metal screws (supplied). As- semble sleeve and attach to firestop with #8 sheet metal screws (supplied). Install firestop assembly.

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” (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)

STEP 5

Use appropriate length of pipe section - telescopic or fixed - and install the horizontal vent sections. The 20” (508 mm) 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.
