DO NOT BURN WET COAL
READ THIS
Always empty hopper when not burning for more than a
week. When left standing for long periods with wet coal,
the pusher block will rust and corrode, causing it to
seize. If the stoker is then turned "on", damage to the
pusher assembly and feed motor will result. This will be
considered neglect and will void the warranty on those
parts. Always check to see if moving parts are free
before using if the unit has not been burned for a period
of time. This can best be determined by shaking the
adjuster rod.
Freshly delivered coal is watered down
to eliminate dust when loading and unloading.
Wet rice coal does not flow as well as damp or
dry coal. We do not recommend burning wet
coal, however, we realize if it's the only coal you
have it is better to burn it than freeze. If you
must burn wet coal, the feed rate must be in-
creased in order to get the same size fire. As the
wet coal in the hopper dries out, the feed rate
must be decreased. If you don’t, the feeder will
over-fire the stove and waste coal. Doing this
once or twice a year will not damage your stove
as long as it is hot and burning. The damage is
caused when the hopper has wet coal in it when
th e s to v e is c o ld .
This will cause rust and corro-
sion and it is totally the operator’s fault.
Usually after the coal dries for three
or four days, depending on conditions, it will
flow very well and feed properly. Feed rate
will be the same as dry coal.
Damp coal also should not be left in
the hopper of a cold stove.
