A. Fuel Specifications

B. General Operating Information

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.

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.

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.

Warning

Route Power cord away from the appliance. Do not run the cord under or in front of the appliance.

1. ESP (Exhaust Sensing Probe)

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.

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

"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".
