vent must not exceed 4-feet. This could cause back
pressure. Use no more than 180 degrees of elbows
(two 90-degree elbows, or two 45-degree and one
90-degree elbow, etc.) to maintain adequate draft.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors.
Too much draft may cause excessive temperatures
in the appliance. Inadequate draft may cause
backpuffing into the room and 'plugging' of the
chimney. Inadequate draft will cause the appliance
to leak smoke into the room through appliance and
chimney connector joints. An uncontrollable burn
or excessive temperature indicates excessive draft.
Take into account the chimney's location to ensure
it is not too close to neighbours or in a valley which
may cause unhealthy or nuisance conditions.
PELLET VENT TYPE
A certified 3-inch or 4-inch type "PL" pellet vent
exhaust system must be used for installation and
attached to the pipe connector provided on the
back of the stove (use a 3-inch to 4-inch adapter for
4-inch pipe). Connection at back of stove must be
sealed using Hi-Temp RTV. Use 4-inch vent if the
vent height is over 12-feet or if the installation is over
2,500 feet above sea level. We recommend the use of
Simpson Dura-Vent® or Metal-Fab® pipe (if you use
other pipe, consult your local building codes and/
or building inspectors). Do not use Type-B Gas Vent
pipe or galvanized pipe with this unit. The pellet vent
pipe is designed to disassemble for cleaning and
should be checked several times during the burning
season. Pellet vent pipe is not furnished with the unit
and must be purchased separately.
PELLET VENT INSTALLATION
The installation must include a clean-out tee to
enable collection of fly ash and to permit periodic
cleaning of the exhaust system. 90-degree elbows
accumulate fly ash and soot thereby reducing
exhaust flow and performance of the stove. Each
elbow or tee reduces draft potential by 30% to 50%.
All joints in the vent system must be fastened by
at least 3 screws, and all joints must be sealed with
Hi-Temp RTV silicone sealant to be airtight. The
area where the vent pipe penetrates to the exterior
of the home must be sealed with silicone or other
means to maintain the vapor barrier between the

exterior and the interior of the home. Vent surfaces
can get hot enough to cause burns if touched by
children. Noncombustible shielding or guards may
be required.
PELLET VENT TERMINATION
Do not terminate the vent in an enclosed or semi-
enclosed area, such as; carport, garage, attic, crawl
space, under a sun deck or porch, narrow walkway, or
any other location that can build up a concentration
of fumes. Termination in one of these areas can also
lead to unpredictable pressure situations with the
appliance, and could result in improper performance
and/or malfunction. The termination must exhaust
above the outside air inlet elevation. The termination
must not be located where it will become plugged
by snow or other materials. Do not terminate the
venting into an existing steel or masonry chimney.
VENT TERMINATION CLEARANCES
A. Minimum 4-foot (1.22m) clearance below or
beside any door or window that opens.
B. Minimum 1-foot (0.3m) clearance above any door
or window that opens.
C. Minimum 3-foot (0.91m) clearance from any
adjacent building.
D. Minimum 7-foot (2.13m) clearance from any
grade when adjacent to public walkways.
E. Minimum 2-foot (0.61m) clearance above any
grass, plants, or other combustible materials.
