with four wood screws 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: The four wood screws provided
should be replaced with appropriate fas-
teners for stucco, brick, concrete or other
types of sidings.
Combustible Exterior Wall: For vinyl
siding, stucco or wood exteriors, a siding
standoff may be installed between vent
cap and exterior wall. The siding standoff
prevents excessive heat from damaging
siding materials. 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 the 10" square hole and attach
to exterior wall with wood screws provided
(see Figure 11). Siding standoff must sit
flush against exterior fascia material.
7. Combustible Exterior Wall Only: Slide
wall firestop over vent pipe before con-
necting horizontal run to vent cap (see
Figure 12).
8. Carefully move fireplace, with vent as-
sembly attached, toward wall and insert
vent pipe into horizontal termination. Pipe
overlap should be a minimum of 1
Figure 13, page 11).
9. Combustible Exterior Wall Only: Slide
wall firestop against interior wall surface
and attach with screws provided. See Fig-
ure 13, page 11, for horizontal termination
details.
10. Place fireplace into position and shim with
noncombustible material if needed. Nail or
screw side flanges to framing to secure
unit in place. IMPORTANT: Make sure fire-
place is level before securing. If fireplace
is not level it will not work properly.
