3.Attach vent pipe assembly to the fireplace. Set fireplace in front of it’s per- manent location to insure minimum clear- ances. Mark the wall for a 10" square hole (for noncombustible material such as masonry block or concrete, a 7 1/2" diam- eter hole is acceptable). See Figure 12. The center of the hole should line up with the center-line of the horizontal rigid vent pipe. Cut a 10"x10" (254mm x 254mm) square hole through combustible exterior wall (7 1/2" [190mm] diameter hole if non- combustible). Frame as necessary (see Figure 12).

4.Apply a bead of non-hardening mastic around the outside edge of the vent cap. Position the vent cap in the center of the 7 1/2" or 10" hole on the exterior wall with the arrow on the vent cap pointing up. Insure proper clearance of 1" to combustibles is maintained. At- tach the vent cap with four wood screws supplied (see Figure 13). Note: Re- place the wood screws with appropri- ate fasteners for stucco, brick, concrete, or other types of siding.

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

For vinyl siding use vinyl siding stand- offs between vent cap and exterior wall. The vinyl siding standoff prevents ex- cessive heat from melting the vinyl sid- ing material. Bolt the vent cap to the standoff. Apply non-hardening mastic around outside edge of the standoff in- stead of the vent cap assembly. Use wood screws provided to attach the

6.Carefully move the fireplace with vent assembly attached toward the wall and insert the vent pipe into the horizontal termination. The pipe overlap should be a minimum of 1 1/4". Apply silicone to the outer pipe connection. Fasten all vent connections with screws provided. Refer to Fireplace Installation on page 16 for instructions on securing unit to framing or floor.
