3. Attach vent pipe assembly to the fire-
place. Set fireplace in front of it’s per-
manent location to insure minimum
clearances. Mark the wall for a 10"
square hole (for noncombustible ma-
terial such as masonry block or con-
crete, a 7
1
/2" diameter hole is accept-
able). See Figure 12. The center of the
hole should line up with the center-
line of the horizontal rigid vent pipe.
Cut a 10"x10" (254mm x 254mm)
square hole through combustible ex-
terior wall (7
1
/2" [190mm] diameter
hole if non-combustible). Frame as

WARNING: Do not recess vent
termination in to any wall. This
will cause a fire hazard.
4. Apply a bead of non-hardening mastic
around the outside edge of the vent cap.
Position the vent cap in the center of
the 7
1
/2" or 10" hole on the exterior
wall with the arrow on the vent cap
pointing up. Insure proper clearance of
1" to combustibles is maintained. At-
tach the vent cap with four wood screws
supplied (see Figure 13).
Note
: Re-
place the wood screws with appropri-
ate fasteners for stucco, brick, concrete,
or other types of siding.
For vinyl siding use vinyl siding stand-
offs between vent cap and exterior wall.
The vinyl siding standoff prevents ex-
cessive heat from melting the vinyl sid-
ing material. Bolt the vent cap to the
standoff. Apply non-hardening mastic
around outside edge of the standoff in-
stead of the vent cap assembly. Use
wood screws provided to attach the
standoff. See Figure 14.
5. Slide the wall thimble over the vent
pipe before connecting the horizontal
run to the vent cap (see Figure 15).
6. Carefully move the fireplace with vent
assembly attached toward the wall and
insert the vent pipe into the horizontal
termination. The pipe overlap should
be a minimum of 1
1
/4". Apply silicone
to the outer pipe connection. Fasten all
vent connections with screws provided.
Refer to Fireplace Installation on page
16 for instructions on securing unit to
framing or floor.
7. Slide the wall thimble against the inte-
rior wall surface and attach with screws
provided (see Figure 15).
