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 the siding materials. Siding material must be cut to accommodate standoff. Bolt the vent cap to the stand- off. Apply
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".
9.Combustible Exterior Wall Only: Slide wall firestop against interior wall surface and attach with screws provided (see Figure 12). See Figure 13, page 10 for horizontal termination 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.
