Fuel

The DVC500 is designed to burn Anthracite Rice Coal, which is approximately 3/8" long and wide by 3/16 thick. Anthracite coal is considered either White Ash or Red Ash.

White Ash Coal will have 13 to 14,000 btu's per lb. White ash coal usually has less ash and will burn longer.

RedAsh coal is usually about 12,000 btu's per lb. and is higher in volatiles. Higher volatiles makes the coal easier to light and produces a more yellow flame.

At a very low burn rate the TCP (Temperature Control Probe) may be activated with Red Ash coal, especially if the hopper lid is open or leaking. The TCP senses the temperature of the feeder and feeds coal if the temperature rises too much. This prevents the fire from reaching the coal in the hopper. Red Ash Coal may form klinkers (fused together ash) which may cause grate blockage in severe cases.

Anthracite Coal can be purchased in bags or in bulk. If you buy in bulk, try to have the coal delivered before temperatures reach the freezing level. This is because salt may be added to the coal to keep it from freezing on the truck. This will not affect burning but will promote rust and corrosion.

Some Coal Companies wash their coal better than others to remove fines and dirt. This makes air flow through the coal better and produces less fly ash.

Whether bagged or in bulk, the coal must be dry before loading it into the stove. At a minimum, open bags a few days in advance to allow drying. Buy your bulk coal mid summer to allow plenty of time for drying.

Good, clean, White Ash Coal is the fuel of choice, "however" Red Ash Coal will also burn well. As long as it is Anthracite.
