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.

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 fire 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 80

F (27

F).

NOTE:

Before loading the fire box, turn the thermostat up to insure 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 fire is established, set the thermostat to desired temperature.

To start the fire, turn up the thermostat to Maximum setting to turn ON Forced Draft Fan. Place some newspaper crumpled up

in the bottom of the firebox on top of the minimum requirement of 2" of sand , ash or firebrick. Add some small kindling and

light the fire. When the fire starts add some larger pieces of kindling or wood until you have a good fire. The idea is to

ultimately end up with a good bed of ash and coals which helps to maintain a good controllable fire.

When reloading the firebox there will be a build up of ash and coals from the previous fire. Rake the coals mixed with ash to

the front of the firebox which places the coals at the front. Throw in your wood and the fire should light in a few minutes.

When the firebox gets full of ash (within one inch of door level), some morning , before loading the firebox , push or rake the

coals to the rear of the firebox. Remove the ash from the front of the firebox 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 fire will

again be burning in a few minutes. The fire burns best when the ashes are 3" to 4" below the fire 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 firebox 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 sufficient 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 filters. The draft fan will be off, so if more

combustion air is needed for the wood fire, open the slide plate damper in the fire door. This damper must be closed when

power is returned to normal.

DO NOT CHARGE the fire box higher than half way up the liner as overheating may result.
