Maintenance & Cleaning Continued

First, you will need to locate the cover plates to the rear exhaust chambers. These chamber covers are
small, rectangular, metal plates that are affixed with 2 wing nuts or Allen screws.
There are two total chamber cover plates. One on each side of the stove behind the side panels.
One is about 6 inches below the air intake damper.
The other is on the top portion of the square exhaust pipe, adjacent to the exhaust motor housing.
(IMPORTANT)
Rear Exhaust Chambers: Every ton
(50 Bags)
of Pellets Burned or as Needed
In addition to daily and weekly maintenance tasks, the exhaust chamber covers should be removed and the
entire chamber vacuumed thoroughly
once every ton
(50 bags)
of pellets burned or more often depending
on pellet quality.
Once you have located the chamber covers, you will then remove them by unscrewing the wing
nuts/Allen screws and pulling the plate back.
There is a gasket behind the plate to help make an airtight seal so the stove does not draw in air
through these panels. It is ok to cut through the center of the gasket to access the chamber behind it. As
long as there is adequate gasket material around the perimeter, it will provide a proper seal.
Using a slender hose attachment for your ash vacuum, thoroughly vacuum out these chambers top to
bottom. These chambers extend all the way up to the heat exchange tubes near the top of the stove, so
it is imperative that the entire chamber is cleaned.
Using a sweeping motion with a slender, flexible brush will ensure that no area is neglected and as
much of the ash and soot is removed as possible.
(1" - 1½" diameter coil brushes work great)
There is a combustion motor gasket, which allows you to remove the motor from the housing, for
inspection and cleaning. If damage occurs to the gasket, a new blower flange gasket may need to be
added between the blower flange and the steel plate.
Do not over-tighten wingnuts during reassembly.
Exhaust Venting & Combustion Blower Housing: Annually or as Needed
The exhaust venting
(including Tee cleanouts and elbows)
, and combustion motor, housing, and impellers
should be inspected and cleaned once per year or as needed.
