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 mate-
rial such as masonry block or concrete,
1
a 7
/2" diameter hole is acceptable).
See Figure 13. 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 exterior wall
1
(7
/2" [190mm] diameter hole if non-
combustible). Frame as necessary (see

around the outside edge of the vent cap.
Position the vent cap in the center of
the 7

" or 10" hole on the exterior
2
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 14). Note : Re-
place the wood screws with appropri-
ate fasteners for stucco, brick, concrete,
or other types of siding.
WARNING: Do not recess vent
termination in to any wall. This
will cause a fire hazard.
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 15.

Slide the wall thimble over the vent pipe
before connecting the horizontal run to
the vent cap (see Figure 16).
