VENTING INSTALLATION

3.Attach vent pipe assembly to the fire- place. Set fireplace in front of it’s per- manent location to insure minimum clearances. Mark the wall for a 10" square hole (for noncombustible ma- terial such as masonry block or con- crete, a 7 1/2" diameter hole is accept- able). See Figure 17. 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 ex- terior wall (7 1/2" [190mm] diameter hole if noncombustible). Frame as nec- essary (see Figure 17).

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 18). 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 standoff. See Figure 19.

5.Slide the wall thimble over the vent pipe before connecting the horizontal run to the vent cap (see Figure 20).

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 connection. Fasten all vent connec- tions with screws provided. Refer to Framing on pages 4 and 5 for instruc- tions on securing unit to framing or floor.

7.Slide the wall thimble against the inte- rior wall surface and attach with screws provided (see Figure 20).
