VENTING INSTALLATION INSTRUCTIONS

Continued

WARNING: Do not recess vent termination into any wall. This will cause a fire hazard.

6.Noncombustible Exterior Wall: Position the horizontal vent cap in the center of the 8 1/2" round hole and attach to the exte- rior wall with four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around the outside edges to make a seal be- tween it and the outside wall. Note: The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.

Combustible Exterior Wall: For vinyl siding, stucco, or wood exteriors, a siding standoff must be installed between the vent cap and exterior wall. The siding standoff prevents excessive heat from damaging the siding materials. Siding material must be cut to accommodate standoff. Bolt the vent cap to the stand- off. Apply non-hardening mastic around outside edge of stand- off. Position the standoff/cap assembly in the center of the 10 3/4" square hole and attach to exterior wall with wood screws provided (see Figure 11). The siding standoff must sit flush against the exterior fascia material.

7.Combustible Exterior Wall Only: Slide the wall firestop over the vent pipe before connecting horizontal run to vent cap (see Figure 12).

8.Carefully move fireplace, with vent assembly attached, toward wall and insert vent pipe into horizontal termination. The pipe overlap should be a minimum of 11/4". Fasten all vent pipe connections (except vent cap) with screws provided.
