USE OF COAL OVERVIEW
A coal fire is much more challenging to start and is more difficult to manage than a wood fire or gas burner� Simply getting
anthracite coal burning requires an ignition source in excess of 900 °F that is usually provided by a bed of burning charcoal� Dry
wood by comparison burns more quickly and starts burning at around 450 °F� Coal has roughly twice the heat/energy potential of
wood (13,000 BTU/hr per pound for coal versus roughly 6,500 BTU/hr per pound for wood) so accessing and managing its potential
energy when and where you need it can be challenging�
Unlike a wood fire, a coal fire will not let you stir its fire or move it around without consequence� Balancing the open flame of a coal
fire with the intensity of the coal bed becomes the daily challenge� If you load too much fuel, the intensity of the fire will melt metal
along with your pizza� If you load too little fuel, you will find yourself starting all over to recapture the intense heat you lost by letting
the coal fire burn too long without attention�
WHAT YOU NEED TO GET STARTED
Safety glasses, solid fire starter,
lump wood charcoal,
anthracite coal
(the only Wood Stone approved type of coal), 25 pound scale,
large metal bowl, paper grocery bags, wood/coal cart, double compartment Ash Dolly, Ash Chute tool, in-line floor brush, natural
fiber brush, utility peel, large pizza peels�
Never use a liquid-type fire starter or liquid fuel as a fire starter.
COAL-FIRED OVEN OPERATIONAL GUIDELINES
The typical desired hearth temperature for Wood Stone coal-fired ovens is 550-580 °F�
CAUTION:
Over firing the oven with coal
may cause damage to the oven ceramics� If the oven deck temperature is above 850 °F, or flames exit the doorway or flue of the
oven, you are over firing� Only use anthracite coal—see notes contained earlier in this manual�
