Maintenance
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 pellets being used. Keep
in mind that the cleaner the heat exchanger surface is kept,
the higher the heat transfer efficiency will be.
Due to it’s ease of restarting it is recommended that the
boiler be OFF and COOL before cleaning.
Start by pulling the (3) heat exchanger cleanout rods by
pulling and pushing these rods vigorously severl times. It will
remove any fly 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 efficiencies. Make sure that these rods are
pushed in at all times.
Cleaning Steps

the firebox. With a wisp brush, wire brush, stiff bristled paint
brush or a soot vac, clean the firebox walls and any fly ash
