WARNINGS
Never sleep in the same
room with any coal
burning stove.
This all new design by Harman features the Verti-Flow Stoker System.
This unique system provides a very wide range of heat output. The
Verti-Flow Stoker can operate from 5000 to over 85,000 btu's automatically.
This unit has a 100 pound coal capacity and can provide 85,000 btu's
for 17 hours or stretch out to over 100 hours when less heat is required.
A thermostat is used to regulate the heat output of the stove. When no
heat is needed, the stoker stops and only runs to maintain the fire. If heat is
needed, the thermostat can turn on the stoker at any time. After the thermostat
is satisfied, the stoker will turn off for twelve minutes and then run for four
minutes.
The four minutes "on" and twelve minutes "off" is a setting that will
perform well under most conditions. This "on" and "off" time can be changed
to provide more or less heat during the maintenance cycle.
This unit must be connected to a chimney capable of providing a .04
minimum draft reading. WARNING!! If the chimney has no draft, coal gases
may escape from the unit and stovepipe. These gases are toxic and can be
fatal. It is recommended that a gas detector be installed to warn of this
condition. Check with your local stove dealer for purchasing a gas detector.
TESTING INFORMATION
This unit has been tested and approved by OMNI-TEST Labo-
ratories in accordance to the listed codes.
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
4
before using if the unit has not been burned for a period
of time. This can best be determined by shaking the
adjuster rod.
Wet Coal
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 increased 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
the sto ve is co ld .
sion and it is totally the operator’s fault.
This will cause rust and corro-
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.
