Masonry, or other non-combustible products, attached directly to a combustible surface without an air space offer very little protection and cannot be considered a clearance reducer unless specified materials have been tested and listed for direct attachment to a combustible surface. The same applies to thin veneer brick and stone coverings. These materials provide adequate protection only when mounted on sheet metal with a 1 inch spacing to the wall. A variety or prefabricated clearance reduc

OPERATING INSTRUCTIONS Burning Coal in your 4027/ASA7 Your Wondercoal is capable of burning both bituminous and Anthracite coal. Anthracite is the best coal fuel because its long even burn time, high heat output, and cleanliness make it a good choice for the home. However, keep in mind it is a much more difficult fuel to use and requires more care and patience. SIZE OF COAL: Most sizes of bituminous coal will work in your heater; for best results we recommend large nut coal to small egg coal

OPERATING INSTRUCTIONS continued... Loading • Coal should never be added unless there is a reasonable hot fire. The coal bed should be bright and vigorous. • If the fire is burning hot and there is a deep bed of coals, full loads of coal can be added at any time. However, if there is not a deep bed of coals, it is best to add small amounts of coal at first. Increasing Heat From a Low Fire • Every effort should be made not to let a coal fire burn too long so that the fire has started to die.

OPERATING INSTRUCTIONS continued... Safety • Before opening the loading door, open the pipe damper and the ash door first. • Whenever a loading door is opened, it always should be cracked slightly to allow oxygen to enter and burn any combus- tion gases that are present before fully opening. Failure to do this could result in sudden ignition of the unburned gases when the door is opened. • A stove never should be filled with excessive coal so that the flue gas exit is blocked or impeded in any
