Operating Instructions
A. Fuel Specications
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 dened
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.
WARNING
"NEVER USE GASOLINE, GASOLINE-TYPE LANTERN
FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR
SIMILAR LIQUIDS TO START OR "FRESHEN UP " A
FIRE IN THIS HEATER. KEEP ALL SUCH LIQUIDS WELL
AWAY FROM THE HEATER WHILE IN USE".
B. General Operating Information
The Super Magnum's ESP control will maintain an
output level to t your temperature demands. There are
two modes of operation; "Stove Temp" mode, where the
control will maintain a specied 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 specied 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.
WARNING
ROUTE POWER CORD AWAY FROM THE APPLIANCE.
DO NOT RUN THE CORD UNDER OR IN FRONT OF
THE APPLIANCE.
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.
Freshly delivered coal is watered down to eliminate
dust when loading and unloading. Wet rice coal
does not ow 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 re.
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.
