Horizontal Termination
„ Wall Cut-out Opening: A minimum 10" X 10" (250 mm x
250 mm) square hole is required for proper pipe clear-
ances through a combustible wall. Use vent
manufacturer’s WALL THIMBLE for the wall penetration.
DO NOT FILL AIR SPACE WITH ANY TYPE OF INSULATION.
„ The minimum horizontal run made directly off the
rear of the stove into a standard horizontal cap shall
be no less than a 6” vent section. See fig. 8.
„
The maximum horizontal run made directly off the
rear of the stove into a standard horizontal cap (#984
or #985) must include no more than a 12” and 6”
section of Simpson Dura-Vent pipe installed together.
See fig.9.
„
The maximum horizontal run made directly off the
rear of the stove into a 14” snorkel cap must include
no more than a 24” vent section . See fig. 10.
„ The horizontal termination cap must maintain a 3"
clearance to any overhead combustible projections
2 1/2" or less. It must also maintain 12" clearance
from projections exceeding 2 1/2". See fig. 14.
„ Any horizontal run of vent must be level or have a
1/4" rise for every foot of run toward the termination
cap. NEVER ALLOW THE VENTING TO RUN DOWN-
WARD FROM STOVE TO TERMINATION; DOWNWARD
VENT RUNS TRAP HEAT AND CAUSE HIGH TEMPERA-
TURES TO DEVELOP WITHIN THE VENT THAT COULD
START A FIRE.
„
Install a Vinyl Siding Standoff between the vent
termination and an exterior wall covered by vinyl
siding material to prevent potential heat damage to
the siding.
„
Do not recess the termination cap into a wall or
siding.
