Do Not Burn Wet Coal!
Super-Magnum Coal Stoker Stove
3-90-02702R8_11/13
A. Fuel Specifications
The Super Magnum is designed for use with Anthracite
"Rice" coal Only. Anthracite is a hard coal which is mined
mostly in the Eastern United States. The post-mining
process involves breaking the large lumps of anthracite into
smaller, usable sized pieces. In the breaking process, the
coal is sifted and sorted by different sized screens. Rice
size is basically defined as the coal that has a maximum
size of 3/8" and a minimum size of 3/16".
Most coal suppliers wash the coal and/or wet it for delivery,
to keep the dust minimized. However, the coal must be
dry when loading it in the stove. Therefore, it is highly
recommended that you purchase your coal well ahead of
the heating season, to allow it time to dry. Coal, whether in
bags or in bulk, should be stored in a dry area.
B. General Operating Information
The Super Magnum's ESP control will maintain an output
level to fit your temperature demands. There are two
modes of operation; "Stove Temp" mode, where the control
will maintain a specified constant temperature, regardless
of the surrounding environment temperature conditions,
Or "Room Temp" mode, where the control will adjust the
rate of burn to meet a specified room temperature setting.
Regardless of the mode selected, operation is controlled
by both, exhaust temperature- being reported by the ESP
(Exhaust Sensing Probe), and the microprocessor circuit
board.
We'll discuss these control devices and their functions now.
1. ESP (Exhaust Sensing Probe)
The ESP is a tiny thermistor located in the exhaust stream.
The probe changes it's thermal resistance based on minute
changes in temperature, which is monitored by the circuit
board and used to determine the need for changes in the
burn rate to meet the temperature demand.
CAUTION: Approved for use with coal only. The use of
any other fuel, except for the purpose of igniting the
coal, will void the product warranty and may cause
damage to the appliance and/or your home.
NOTICE
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 to be cold. If you must burn wet
coal, the feed rate may need increased in order to get
the same size fire. 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 while
the stove is not in use. This will cause rust and corrosion
which is not covered by your warranty.
