REAR AIRFLOW/EXHAUST CHAMBER
Figure 33C: Exhaust Chamber Cover Plate.
Gaskett
In addition to daily and weekly maintenance
tasks, the exhaust chamber covers should be
removed and the entire chamber vacuumed
thoroughly once every 1.5 tons of pellets burned.
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. There are a total of
4 chamber covers. They are located on each
side of the stove. (2 left, and 2 right - top and
bottom). These are accessed via the side
panels. See Figure 33A, 33B, and 33C
Once you have located the chamber covers, you
will then remove them by unscrewing the wing
nuts 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 on your ash vac,
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, top to bottom. Using a cross-
hatching/sweeping motion will ensure that no
area is neglected and as much of the ash and
debris is removed as possible.
