Horizontal Termination
„ Any horizontal termination must fall within the
shaded portion of the vent window graph illustrated
in figs. 9 or 11. For Snorkel Terminations, see below.
„
Any horizontal termination except a snorkel termination,
must include:
1)
Minimum rise of 24 in.
2) Minimum horizontal run of 12 in. when vertical
run is less than 8 ft.
3) Vertical run no more than 35 ft.
4) Horizontal run no more than 27 ft.
5) No more than four 45° or two 90° Elbows
„ 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. 21.
„
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.
DO NOT FILL AIR SPACE WITH ANY TYPE OF INSULATION.
„ Any horizontal run of vent must be level or have a
1/4 in. rise for every foot of run toward the termina-
tion 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 (Simpson Dura-Vent
#950) 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.

Snorkel Terminations
„ With a 14” Snorkel:
The horizontal run made directly off the rear of the
stove into a 14” snorkel cap should include no more
than a single 12” straight section as shown in fig. 17.
One 45° Elbow may be used for a corner installation as
shown in fig. 19.
