INSTALLATION
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). The connection
at the back of the stove must be sealed using Hi-Temp
RTV. Use a 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 pipes, 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. The 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.

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.
F.
Minimum 3-foot (0.91m) clearance from an forced air
intake of any appliance.
