CAST IRON STOVE AND BURNER SYSTEM
VENTING
INSTALLATION
Continued
3. Attach vent pipe assembly to the
burner system. Set stove 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 con-
1
crete, a 7 / " diameter hole is accept-
2
able). 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 ex-
1
terior wall (7 / " [190mm] diameter
2
hole if noncombustible). Frame as nec-
essary (see Figure 22).

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 / " or 10" hole on the exterior
2
wall with the word "UP" on the vent
cap facing up. Insure proper clearance
of 1" to combustibles is maintained. At-
tach the vent cap with four wood screws
supplied (see Figure 23). 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, stucco, or wood ex-
terior use vinyl siding standoffs be-
tween vent cap and exterior wall. The
vinyl siding standoff prevents exces-
sive 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 24.
5. Slide the wall thimble over the vent pipe
before connecting the horizontal run to
the vent cap (see Figure 25).

6. Carefully move the stove with vent as-
sembly attached toward the wall and
insert the vent pipe into the horizontal
termination. The pipe overlap should
be a minimum of 1
to the outer pipe connection. Fasten all
vent connections with screws provided.
7. Slide the wall thimble against the inte-
rior wall surface and attach with screws
provided (see Figure 25).
