Operating Instructions
IMPORTANT: Keep ash drawer empty.
Primary air to the wood chamber
travels under the grate. The grates will
warp and eventually burn out if ashes
are permitted to build up above them.
CAUTION: RESTRICTED USE DURING
ELECTRIC POWER FAILURE OR
FURNACE FAN FAILURE
Furnace may be converted to a gravity system.
The following directions must be followed carefully
to avoid an over-fire situation.
1. Remove access door to blower compartment
and remove air filter. Then replace access door.
Keep ash drawer tightly closed. Do not tamper
with wood primary air control. Load wood to
half the recommended normal height,
approximately 4 inches above grate.
2. Do not overload, no furnace fan is available to
rapidly carry away the heat. Load small
amounts of wood frequently until power is
restored.
3. Open all air registers and remove all
obstructions near them. Keep children away
from air registers or burns could result.
4. Primary air damper and burner will operate
automatically when electric power is restored.
STARTING WOOD FIRE WITH GAS OR OIL BURNER
Place three or four 6 to 8 inch diameter logs in the
firebox. Set the temperature on the small thermostat to
the desired setting. Set the temperature on the larger
thermostat above room temperature. The flame from the
burner need not touch the wood to ignite.
HAND FIRING WOOD
Set the small thermostat above room temperature. Set
the larger thermostat below room temperature. The
damper to the firebox should now be open.
Place paper and kindling in firebox as you would in a
fireplace or campfire. Add logs to top of fire once
kindling is burning. Reset small thermostat to desired
room temperature.
Never leave ash drawer open, either to start fire or to
provide more heat. The furnace is designed to provide
adequate heat with the ash drawer closed.
WARNING: Never operate furnace with
ash drawer open. It could cause fire to
burn at extreme temperatures, causing
metal fatigue, firebox failure, and unsafe
duct temperature.
CAUTION: OVERLOADING WITH WOOD
Do not overload your furnace with wood.
Failure or damage to the firebox could
result. Never allow the hot coals to build
up above the lower firebricks.
DANGER: Never burn materials other
than coal or wood logs, preferably split
and dried. A chimney fire or heat
exchanger failure could result. This
includes large amounts of corrugated boxes, wood
shavings, paper scraps, dried Christmas trees,
coke, garbage, tires or other burnable products.
