STEP 1

Locate vent opening on the wall. To locate hole center consult with appropriate fireplace dimensions, Page 4. Frame as shown below.

NOTE: When using flex vent, the opening will have to be measured according to the 1/2” (13 mm) rise in 12” (305 mm) vertical run.

Combustible Walls (Fig. 15): Cut a 10³⁄”H x 9³⁄” W (264 x 240 mm) hole through the exterior wall and frame as shown.

Noncombustible Walls (Fig. 15): Hole opening must be 7¹⁄” (190mm) in diameter.

STEP 2

Measure wall thickness and cut zero clearance sleeve parts to proper length (MAXIMUM 12”/305 mm). As- semble sleeve and attach to firestop with #8 sheet metal screws (supplied). (Fig. 16)

STEP 3

Measure from the fireplace collar or elbow face to face of outside wall (add 2” for vent pipe overlap). Mark pipes and cut to length. It is very important that the two pipes are flush with the outside wall once the fireplace is in its final location. (Fig. 17)

STEP 4

Slip 4” and 7” pipes onto respective flue collars. Make sure to fix to the fireplace collar the 4” pipe with three

(3)screws before fixing the 7” pipe on the 7” collar. Both pipes must be on a level plane. (Fig 18)

STEP 5

Guide the vent termination 4” collar into the 4” pipe then the 7” collar into the 7” pipe. Do not force the venting into position. If the pipes do not line up with the termi- nation collars, disassemble pipes and reattach to the fireplace collar. (Fig. 18)

STEP 6

Secure fireplace to floor through floor holes and adjust- able frame drywall strip (nailing flange) to frame. (Refer to Framing & Finishing Section).
