provided. Before attaching vent cap to exterior wall, run a bead of non-
hardening mastic (pliable sealant) around outside edges to make a seal
between it and outside wall.
Note: Four wood screws provided should be replaced with appropriate
fasteners for stucco, brick, concrete or other types of sidings (see Figure
11).
Combustible Exterior Wall: For vinyl siding, stucco or wood exteriors,
a siding standoff may be installed between vent cap and exterior wall.
Siding standoff prevents excessive heat from damaging siding materi-
als. Siding material must be cut to accommodate standoff. Bolt vent
cap to standoff. Apply non-hardening mastic around outside edge of
standoff. Position standoff/cap assembly in the center of 11
hole and attach to exterior wall with provided wood screws (see Figure
12, page 12). Siding standoff must sit flush against exterior fascia
material.
6. Connecting Vent Cap with Horizontal Vent Pipe: Slide wall firestop over
vent pipe before connecting horizontal run to vent cap (see Figure 13,
page 12).
Carefully move fireplace, with vent assembly attached, toward wall and
insert vent pipe into horizontal termination. Pipe overlap should be a
minimum of 1 / " (see Figure 14, page 12).

not level it will not work properly.
