STOVE PIPE INSTALL/ HELPFUL HINTS
This stove has no need for electricity, it operates with a natural draft, the strength of the draft is determined
by the height of its chimney, and that’s why the chimney installation is the determining factor on how well this
stove will perform. This stove will operate best with a straight chimney either 3” diameter or 4” diameter with 8
ft to 12 ft overall height, although it will operate with many variance’s of chimney height and con gurations,
they will all bring varied results in burn time and fuel usage. A straight chimney is always the best con guration
for this pellet stove.
When 8 ft to 12 ft length of chimney is used 3” diameter chimney will do, when having to use more than 15ft
of chimney, then 4” diameter vent is best. Taller or longer chimney system’s may need a barometric damper
installed immediately off the top of the stove to be able to control the stove down in the 400 degree heat
range as you can experience excessive draft and the stove will want to run hotter. You can also adjust the
bars closer together on the burn basket to lower temp if it starts running to hot.
A 4” diameter pipe is recommended if you decide to go through the wall, and you need to terminate above
the roof at least 24” using pellet vent. When going into a existing chimney then you must run 4” vent all the
way through any existing chimney.
Use minimum 24 gauge single wall pipe in 4, 5 or 6 inch diameter when connecting to listed factory built chimney.
Use a 3-4, 3-5 or 3-6 inch increaser directly
off the stove then connect to the required
length of pipe to reach the factory built
chimney, a slip joint can be used to allow
connection to the factory built chimney
or a plug can be inserted at the entry
point of the factory built chimney. The
connector pipe shall pass through the
plug a minimum of 4 inches or can pass
through the entire length of the chimney.
When using this method install another
properly sized plug at the top of the
chimney and continue connector pipe
out and above the plug at least 2 inches.
Install proper sized cap or in the event
factory built cap is already in place with
spark arrester, the connector pipe can
be terminated under the existing factory
built cap.
When installing your stove, an all vertical
stove pipe, straight up and through the
roof is best. This will insure a good upward
draft that all stoves need to operate. The
more twists and turns you have in stove
piping the more it will restrict the draft,
this is true for all stoves.
IMPORTANT: It is important for the stove
pipe to extend to at least
as high as the highest point of your roof.
Any reduction in clearance to
combustibles may
only be done by means approved
by a regulatory authority. Install vent
at clearances specifi ed by the vent
manufacturer.
