VENT PIPE ASSEMBLY

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. 17).

(For combustible walls first frame in opening. Fig. 17)

COMBUSTIBLE WALLS: Cut a 9-3/8”H x 9-3/8” W (240

mmx 240 mm) hole through the exterior wall and frame as shown Fig. 14.

NONCOMBUSTIBLE WALLS: Hole opening must be 7.5” (190 mm) in diameter.

STEP 2

Measure wall thickness and cut zero clearance sleeve parts to proper length (MAXIMUM 12”/305 mm). Assem- ble sleeve and attach to firestop with #8 sheet metal screws (supplied). Install firestop assembly (Fig. 18).

Zero clearance sleeve is only required for combustible walls.
