Venting
This stove is approved for venting with Type L and Type PL pellet vent
pipe listed to UL 641 and ULC S609. We recommend the use of venting
products manufactured by Security Chimneys International. Single wall
pipe cannot be used with this pellet stove. The stove’s flue collar is 3” in
diameter. An approved wall thimble or approved ceiling firestop must be
used when the pellet pipe passes through a combustible wall or ceiling.
The stove’s combustion blower pressurizes and pushes flue gases out
the pellet pipe. As a result, all pipe joints should be locked together or
screwed with three screws if the pipe does not have a locking system
and sealed with high temperature silicone. The pipe should be siliconed
and fastened with three screws to the stove’s flue collar.
Where the venting may pass through a wall, or partition of combus-
tible materials, the installation shall conform to CAN/CSA-B365. When
installing the wall thimble and other venting components, follow the
vent manufacturers instructions. Maintain an effective vapor barrier at
the location where the chimney or other component penetrates to the
exterior of the structure.
The longer the run of pipe and the more elbows used, the greater the
resistance to the flow of flue gases. Four inch diameter pellet pipe is
recommended for pipe runs greater than 15 feet or when a number of
elbows are used.
To aid in cleaning, whenever possible, the venting system should include
a tee with clean out attached to the flue collar on the stove.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING
SYSTEM OF THIS UNIT. DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
Horizontal installations that terminate without any vertical sections of
pipe are approved; however, wind may direct flue gases toward the house
causing discoloring problems. For this reason, horizontal and up 5 feet or
horizontal and through the eave installations are recommended.
