Cleaning
This cleaning should be done after each ton of pellets
used. The frequency of this cleaning will be directly
related to the quality and the ash content of the pel-
lets being used. Keep in mind that the cleaner the heat
exchanger surface is kept, the higher the heat transfer
efciency will be.
Due to it’s ease of restarting it is recommended that the
boiler be OFF and COOL before cleaning.
Start by actuating the (3) heat exchanger cleanout rods
by pulling and pushing these rods vigorously several
times. This action will remove any y ash built up on the
heat exchanger tubes. This can also be done at any time
during the operation of the boiler to maintain higher ef-
ciencies. Make sure that these rods are pushed in when
cleaning is completed.
Cleaning Steps
-Open the hopper swing plate to access burnpot and
also the rebox. With a wisp brush, wire brush, stiff
bristled paint brush or a soot vac, clean the rebox walls
and any y ash that has accumulated on the ledges of the
burnpot, or burnpot opening. At this time you can scrape
and clean the burnpot and nes cleanout area.
-Open rebox door and vacuum ash from ledges and
ash deector. You can also clean the rebox door viewing
glass using a typical glass cleaner and soft cloth.
-Open the ash door and remove the ash pan. Dispose
of any ash that has accumulated in the ash pan as well
as any y ash from within the ash pan area.
-Remove the (4) thumbscrews on the secondary
ash chamber access plate and remove it to access the
secondary ash chamber. Remove all y ash from this
area. This process should be done as needed.
-Inspect all sealing gaskets to ensure a proper seal
and re-install all components removed for cleaning.
CAUTION: Cleanout of the heat exchanger, ue
pipe, chimney, and combustion blower fan housing,
is especially important at the end of the heating
season to minimize corrosion during the summer
months, caused by accumulated ash.
NOTE: To minimize the amount of stress placed on
the hopper swing plate hinges, opening of the hopper
swing plate should be done with the least amount of
fuel in the hopper as possible.
