Noncombustible Walls (Fig. 15): Hole opening must be 7¹⁄₂” (190mm) in diameter.

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)
