BURNING WOOD OPERATING INSTRUCTIONS
When installation is complete, close the supply switch and turn the thermostat above room temperature. Check
to make sure the forced draft fan above the re door is operating when the thermostat is set above room
temperature. The draft fan should be off when thermostat is set below room temperature. The maximum draft is
not to be more than - .05 as damage may result to the furnace when operated as a gravity unit. The circulating air
blower speed is adjusted at the factory to give an adequate temperature rise under most conditions. However,
because of various temperatures that can result from burning wood, the blower speed can be adjusted by the
motor pulley. Under no circumstances should the temperature rise be more than 80oF (27oF).
To start the re, turn up the thermostat to Maximum setting to turn ON Forced Draft Fan. Place some newspaper
crumpled up in the bottom of the rebox on top of the minimum requirement of 2” of sand , ash or rebrick. Add
some small kindling and light the re. When the re starts add some larger pieces of kindling or wood until you
have a good re. The idea is to ultimately end up with a good bed of ash and coals which helps to maintain a
good controllable re.
When reloading the rebox there will be a build up of ash and coals from the previous re. Rake the coals mixed
with ash to the front of the rebox which places the coals at the front. Throw in your wood and the re should light
in a few minutes. When the rebox gets full of ash (within one inch of door level), some morning , before loading
the rebox , push or rake the coals to the rear of the rebox. Remove the ash from the front of the rebox using
only the shovel supplied for this purpose. When the ashes only are removed from the front , rake the coals from
the back to the front. Throw in your wood and the re will again be burning in a few minutes. The re burns best
when the ashes are 3” to 4” below the re door level. Return wood thermostat in main living space to regular
setting. For safe operating procedure, refer to the “Notice” label on the furnace.
COMBUSTION AIR CONTROL
The amount of combustion air allowed to enter into the rebox can be controlled by means of the Draft Control
slide on the draft fan mounting plate. Set this slide plate to the position that allows sufcient combustion air in for
the type of solid fuel being burned. Normally the setting is in the center between maximum and minimum, then
if additional control is needed it can be adjusted accordingly. When burning coal it must be set at maximum, for
burning wood it will vary with size and type. DO NOT LET THE COALS/ASHES BUILD UP ANY HIGHER THAN HALF WAY
UP THE FIRE BOX LINER.
POWER FAILURE
In case of prolonged power failure, remove the blower access door and air lters. The draft fan will be off, so if
more combustion air is needed for the wood re, open the slide plate damper in the re door. This damper must
be closed when power is returned to normal. DO NOT CHARGE the re box higher than half way up the liner as
overheating may result.
NOTE: Before loading the re box, turn the thermostat up to ensure that the draft fan is on. This provides an air
curtain to avoid smoke roll out during loading and fans the coals to assist the ignition process of your new fuel.
It also helps to promote draft when there is inadequate draft. After the re is established, set the thermostat to
desired temperature.
SUMMER SHUT DOWN
When burner is not to be used during the summer months turn off burner main switch. If the heating unit room is
damp, protect burner against dirt and moisture with light cover.
SAFETY SHUT-OFF
An emergency oil shut-off valve should be installed as required by local ordinance. Always keep the valve shut-
off if the burner is shut down for an extended period of time.
SERVICE
If burner fails to run when the thermostat or other operating control is calling for heat see that the main switch is
turned on and that fuses are not blown. Be sure there is oil in the supply tank and that the electric service to the
building has not been temporarily interrupted. Press button on burner control box and if burner still fails to start call
the service man. A periodic inspection of the burner is recommended.
