Horizontal Vent Installation
Venting terminals may not be recessed into a wall
or siding.
1) Set the unit in the desired location. Check whether or
not wall studs are in the way when the venting system is
attached. If wall studs are in the way, you may want to
adjust the location of the unit.
2) Assemble the desired combination of pipe and elbow to
the appliance adaptor with pipe seams facing down. Off-
setting the pipe seams as double seams in one place will
cause the outer pipe to take an oval shape. The Horizontal
Termination Kit comes with 18” of straight vent - 6-5/8”
black outer pipe and 4” inner vent.
3) With the pipe attached to the stove, slide the stove into
its correct location and mark the wall to the dimensions
of the wall thimble (9-1/4” x 10-1/4”). The center of
the round hole should line up with the centerline of the
horizontal pipe. (9-1/4” is side-to-side dimension and
10-1/4” is vertical dimension) If the wall being penetrated
is constructed of non- combustible material (i.e. masonry
block or concrete), a 7” diameter hole is acceptable.
4) The horizontal run of vent should have a 1/4” rise for every
1 foot of run toward the termination. Never allow the vent
to run downward. This could cause high temperatures
and may present the possibility of a fire.
5) The location of the horizontal vent termination on an ex-
terior wall must meet all local and national building codes
and must not be blocked or obstructed. For External Vent
Termination Locations, see Page 15.
Snorkel Terminations:
For installations requiring a vertical
rise on the exterior of the building, 14-inch (356 mm) and
36-inch (914 mm) tall Snorkel Terminations are available, as
well as the standard Riser Vent. Follow the same installation
procedures as used for standard Horizontal Termination.
NEVER install the snorkel upside down.
