Do Not Burn Wet Coal!

Super-Magnum Coal Stoker Stove

3-90-02702R6_03/13                                                      

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.

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  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.  

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.

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.
