If you are replacing a wood stove with a pellet unit the
chimney should be thoroughly cleaned before proceeding with the
installation. The flue system should be either masonry, or a UL approved
"pre-manufactured Class A" flue system. The flue thimble should be either six
inches (6") or eight inches (8") and the proper reducer (6" to 3" or 8" to
3") can be purchased at your local dealer. Connect a three inch (3") tee
with clean-out to the pipe adapter -- seal this with high temperature stove
cement, then extend your pipe to the installed reducer at the thimble. If
the thimble is in the ceiling, the pipe will go straight up, but if the
thimble is in the wall another 90-degree elbow will be required to make the
Outside Air (Outside Combustion Air Intake)
Outside air is mandatory for this unit to operate properly.
This unit has been designed and tested with this
connection, because so many homes are airtight and there is not adequate
combustion air available inside the dwelling. The air intake pipe is located
on the bottom of the burn pot (from the rear) and measures 1
(I.D.). The connection can be made with a metal 1
7/8" I.D. coupler and pipe (see "Important Information" section of
manual), and should exit through the wall. Be sure to secure the pipe to the
unit with a clamp or aluminum tape. The outside end of the pipe should be
covered (screened) to prevent foreign matter from entering the system. Our
Outside Air Kit (Part Number
PU-OAK) can be used.

use or couple to.
High Altitude Installation
If the unit is being installed at an altitude of 4000 ft above sea level or
higher, the following amendments to the chosen installation should be made.
The pellet vent pipe size should be increased to 4" (Part
