VENTING INSTALLATION
Continued
WARNING: Do not recess
vent termination into any wall.
This will cause a fire hazard.
6. Noncombustible Exterior Wall: Posi-
tion horizontal vent cap in center of 8
round hole and attach to exterior wall with
4 wood screws provided. Before attach-
ing 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: 4 wood screws provided should be
replaced with appropriate fasteners 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. 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 center
of 11 / " square hole and attach to exte-
1
2
rior wall with wood screws provided (see
Figure 11). Siding standoff must sit flush
against exterior fascia material.
7. Connecting Vent Cap with Horizontal
Vent Pipe: Slide wall firestop over vent
pipe before connecting horizontal run to
vent cap (see Figure 12).
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 12).
Slide wall firestop against interior wall
surface and attach with screws provided.
See Figure 13, page 12, for horizontal
termination details.
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.
