any wall. This will cause a fire hazard.

3.

Attach vent pipe assembly to the fireplace. Set fireplace in
front of it’s permanent location to insure minimum clearances.
Mark the wall for a 10" square hole (for noncombustible ma-
terial such as masonry block or concrete, a 7

" diameter

hole is acceptable). See Figure 22. 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 (7

Combustible Exterior Wall:

For vinyl siding, stucco, or wood

exteriors, a siding standoff must be installed between the vent
cap and exterior wall. The siding standoff prevents excessive
heat from damaging siding materials. Siding materials must be
cut to accommodate standoff. Bolt the vent cap to the stand-
off. Apply non-hardening mastic around outside edge of the
standoff. Position the standoff/cap assembly in the center of
the 10" square hole and attach to exterior wall with wood screws

provided (see Figure 24). The siding standoff must sit flush
against the exterior fascia material.

5.

Conbustible Exterior Wall Only:

Slide the interior wall firestop

over the vent pipe before connecting the horizontal run to the
vent cap (see Figure 25).

6.

Carefully move the stove with vent assembly attached toward
the wall and insert the vent pipe into the horizontal termina-
tion. The pipe overlap should be a minimum of 1

". Apply

silicone to the connection. Fasten all vent connections with
screws provided.

Conbustible Exterior Wall Only:

Slide the wall firestop against

the interior wall surface and attach with screws provided (see
Figure 25).
