Vent Cap
Apply Mastic to
All Four Sides
Combustible Exterior Wall: For vinyl siding, stucco, or wood
exteriors, a siding standoff may 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. 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 1
1 /
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.
