How Your New Furnace Works
Unlike conventional heating (gas, oil, electric), wood or coal
heating requires more user attention. Your furnace, with
its automatic combustion air blower, alleviates the constant
need for adjusting the burning rate common to other units
on the market. The fire, however, must be started and
subsequent fuel added by the user.
Conventional heating system produce heat only when the
thermostat calls for heat. This way of heating is inefficient
and often leaves part of the home either too hot or too
cold. Your furnace is designed to deliver heat as long as
there is a fire in it. The fire intensity is regulated by the
room thermostat, high or low, the fire continues to pro-
duce heat. This heat is continuously distributed throughout
the home by a distribution blower. This constant supply of
heat is uniform and prevents drafts.
WARNING
Note: Improper firing. Wood or coal over firing oc-
curs when the ash door is left open during operation
or a highly volatile fuel is used. Coal that exceeds the
fire brick line will cause overfiring...this type of op-
eration will immediately void any warranty.
