VENTING INSTALLATION INSTRUCTIONS

Continued

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 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" square hole and attach to exterior wall with wood screws pro- vided (see Figure 11). The siding standoff must sit flush against the exterior fascia material.

7.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".

9.Slide wall firestop against interior wall surface and attach with screws provided. See Figure 13, page 10 for horizontal termina- tion details.

10.Place fireplace into position and shim with noncombustible ma- terial if needed. Nail or screw side flanges to framing to secure unit in place. IMPORTANT: Make sure fireplace is level before securing. If fireplace is not level it will not work properly.
