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 termina-

tion, must include:
1) Minimum rise of 2 ft.
2) Minimum horizontal run of 12 in. when vertical
run is less than 8 ft.
3) Maximum rise of 35 ft.
4) Maximum horizontal run of 27 ft.
5) No more than four 45° or two 90° Elbows
Follow all termination clearance guidelines as specified

in fig. 19.
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. 20.
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 a listed wall
thimble for the wall penetration.
DO NOT FILL AIR SPACE WITH ANY TYPE OF INSULA-
TION.
Any horizontal run of vent must have a 1/4" rise for ev-

ery foot of run toward the termination cap. NEVER AL-
LOW THE VENTING TO RUN DOWNWARD FROM STOVE
TO TERMINATION; DOWNWARD VENT RUNS TRAP HEAT
AND CAUSE HIGH TEMPERATURES TO DEVELOP WITHIN
THE VENT THAT COULD START A FIRE.
Install a Vinyl Siding Standoff between the vent termi-

nation and an exterior wall covered by vinyl siding ma-
terial to prevent potential heat damage to the siding.
Do not recess the termination cap into a wall or siding.

Snorkel Terminations
THE AIR INLET RESTRICTOR MUST BE SET FULLY OPEN

FOR ANY SNORKEL TERMINATION. See Fig. 6, pg. 9.


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. 18.


The maximum horizontal run may be no more than
