 Draft is created by the heated air rising in the chimney system. This draft will pull
fresh combustion air into the firebox. Recommended draft is .04 in. w.c. Too little
draft results in a sluggish fire and smoking when the furnace door is opened. Too
much draft (over .07 in. w.c.) is unsafe and wastes fuel. The damper opening has
been set at the factory and should not be adjusted.
 Ashes should be cleaned out when they reach a depth of 4" in the firebox (half way
up the lower bricks). Dispose of ashes in an airtight, metal container and store it
outside away from combustibles.
 OPEN THE FIRING DOOR ONLY TO RELOAD FUEL.
 Your appliance must be vented by a chimney system suitable for solid fuel fired
appliances and should be checked periodically to insure its safe condition.
 Use extreme caution not to over fire during a power failure . Do not fill wood above
the top of the liner bricks. The furnace is designed as a forced air furnace and
excess firing without the blower running will overheat the firebox and damage will
result.
 If your furnace is operating as an add-on combination unit remember both units will
not fire at the same time. If wood is to be your main source, set the wood thermo-
stat at your desired room temperature and set the backup thermostat approxi-
mately 5 degrees lower.
