Installing Your Stove
Venting Your Stove
The maximum horizontal venting allowed with no vertical
venting attached is 48 inches including one 90° elbow
or two 45° elbows. Addition of any horizontal venting
beyond 48 inches requires a minimum 60 inches of
additional vertical vent. Horizontal sections of vent pipe
should have a 1/4 inch rise per foot. We recommend
using the shortest venting and fewest elbows possible
when venting horizontal.
We recommend the use of 4 inch vent with any
installation requiring more than two 90° elbows, or more
than 15 feet of venting.
• 45° elbow is equivalent to 1 foot of straight pipe
• 90° elbow is equivalent to 3 feet of straight pipe

WARNING!
Fire Risk.
• Only LISTED venting
components may be
used
• NO OTHER vent components may be used.
Substitute or damaged vent components
may impair safe operation.
Notice:
These are guidelines for successful venting of
your pellet appliance. The more vertical rise
you can obtain in your system, the better it will
perform. Horizontal vent runs can accumulate
ash and will need to be cleaned more often.
Try to keep them as short as possible.
