VENTING INSTALLATION

3.Attach vent pipe assembly to the fireplace. Set fireplace in front of it’s permanent location to insure minimum clearances. Mark the wall for a 10" square hole (for noncombustible ma- terial such as masonry block or concrete, a 7 1/2" diameter hole is acceptable). See Figure 21. The center of the hole should line up with the center-line of the horizontal rigid vent pipe. Cut a 10"x10" (25.4cm x 25.4cm) square hole through combustible exterior wall (7 1/2" [19.1cm] diameter hole if noncombustible). Frame as necessary (see Figure 21).

4.Noncombustible Exterior Wall: Apply a bead of non-harden- ing mastic around the outside edge of the vent cap. Position the vent cap in the center of the 7 1/2" hole on the exterior wall with the arrow on the vent cap pointing up. Attach the vent cap with four wood screws provided (see Figure 22). Note: Replace the wood screws with appropriate fasteners for stucco, brick, con- crete, or other types of siding.

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

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 siding materials. Siding materials must be cut to accommodate standoff. Bolt the vent cap to the stand- off. Apply non-hardening mastic around outside edge of the standoff. Position the standoff/cap assembly in the center of the 10" square hole and attach to exterior wall with wood screws provided (see Figure 23). The siding standoff must sit flush against the exterior fascia material.

5.Conbustible Exterior Wall Only: Slide the interior wall firestop over the vent pipe before connecting the horizontal run to the vent cap (see Figure 24).

6.Carefully move the stove with vent assembly attached toward the wall and insert the vent pipe into the horizontal termina- tion. The pipe overlap should be a minimum of 1 1/4". Apply silicone to the connection. Fasten all vent connections with screws provided.

7.Conbustible Exterior Wall Only: Slide the wall firestop against the interior wall surface and attach with screws provided (see Figure 24).
