6. Hopper
• Frequency: As necessary / Yearly
• By: User
Whenever the hopper is low or empty, take the time to
inspect the hopper throat area for any larger pieces of coal
or foreign objects. This is also a good time to vacuum any
coal residue or dust from the hopper.
Remember to empty and clean the hopper at the end of
the burn season or whenever the stove is not going to
be operated for a few days. This will help to prevent rust
formation in the hopper and feed system.
7. Firebox
• Frequency: As necessary / Yearly
• By: User
Cleaning the firebox and internal heat exchange surfaces is
recommended to maintain thermal efficiency. Depending on
the quality and quantity of coal being used, you may want to
perform this cleaning monthly.
Be sure to clean these areas thoroughly at the end of the
heating season.
Brush and vacuum all internal surfaces. Lift the grates and
thoroughly clean the air flow area under the grates. (See
drawing below).
This cross sectional cut-away illustration shows an internal view of the
heat exchange, plus you can also see how the grates are removed by
lifting them out of the frame.
