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 Stove. 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.

Installing Your Stove

•
Install pellet venting through wall and connect vent/pipe to Stove
•
Some venting manufacturers offer pellet Stove adapters for their
venting for easier installation
•
Seal all pipe joints using high-temp silicone (500°+)
•
Secure exhaust venting system to the Stove with at least 3 screws or
rivets per the pipe manufacturer's instructions. Also secure all connector
pipe joints with at least 3 screws through each joint.
•
Install termination cap
•
Confirm all required Stove clearances to combustibles
Pro Tip
Installing a clean-out "T" (sold separately) to the rear
of your Stove, when venting vertically can save time during cleaning.
Install outside air kit (included)

For optimal performance, PelPro recommends the outside air kit for
all installations. Outside air kit is required for all mobile/manufactured
home installations.
