Whenever the loading door is opened, it should be cracked slightly (for about ten (10) seconds) to allow
oxygen to enter and burn any combustible 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. This furnace is equipped
with a safety latch system to reduce the rsik of sucjh an ignition. Always wear a glove to protect you hand
from the heat.
With the exception of the start-up period, the ash pit door should never be left open. Serious damage to the
stove can occur from overheating. In extreme cases, this overheating could be the cause of an "unfriendly
fire".
Coal furnaces are subject to the same installation clearance standards as wood furnaces. Never burn coal
in any furnace that does not have an airtight, unified chimney system.
Coal furnaces should not be installed in any chimney that has had a history of back-drafting or flow rever-
sal. Also, coal furnaces should not be installed in any chimney having an excessively large flue. These
conditions can cause improper draft, resulting in carbon monoxide entering the house rather than being
drawn up the chimney. Remember, coal gases are toxic.
Sulfur dioxide, sulfur trioxide and other ions released from coal burning may corrode stainless and masonry
chimneys, and even terra cotta chimney liners and brick in nearby buildings. Coal with high sulfur content
will destroy chimneys especially fast if soot sits in the flue for extended lengths of time. It is important to clean
chimneys regularly.
