1) Set the unit in its desired location. Check to
determine if wall studs are in the way when
the venting system is attached. If this is the
case, you may want to adjust the location
of the unit.
2) Assemble the desired combination of pipe
and elbow to the appliance adapter with
pipe seams oriented down. Offset the pipe
seams as double seams in one place will
cause the outer pipe to take an oval shape.
Kit comes complete with 18" of straight vent
- 6-5/8" dia. black outer pipe and 4" dia. inner
vent.
3) With the pipe attached to the stove, slide the
stove into its correct location, and mark the
wall for a 9-1/2" (inside dimensions) round
hole. The center of the round hole should line
up with the centerline of the horizontal pipe,
as shown in diagram 1. Cut and frame the
9-1/2 round hole in the exterior wall where
the vent will be terminated. If the wall being
penetrated is constructed of non-combusti-
ble material, i.e. masonry block or concrete,
a 7" diameter hole is acceptable.
Note:
a) The horizontal run of vent should have
a 1/4 inch rise for every 1 foot of run
towards the termination. Never allow the
vent to run downward. This could cause
high temperatures and may present the
possibility of a fi re.
b) The location of the horizontal vent ter-
mination on an exterior wall must meet
all local and national building codes,
and must not be blocked or obstructed.
For External Vent Terminal Locations,
see diagram in "Exterior Vent Terminal
Locations" section.
c) Snorkel Terminations:
For installations requiring a vertical rise
on the exterior of the building, 14-inch
and 36-inch tall Snorkel Terminations
as shown in Dia. 2 are available, as
well as the standard Riser Vent. Follow
the same installation procedures as
used for standard Horizontal Termina-
tion. NEVER install the snorkel upside
down.
