OPERATING INSTRUC-

TIONS

FUEL

Egg size Bituminous coal for residential furnaces, or any of the specially pack- aged fireplaces coals can be used. Coal with a low ash content (2% to 6%) is recommended.

NOTE: Store coal in a dry, well-venti- lated area.

LIGHTING

1.Set the thermostat on "High" for maximum draft.

2.Open the feed door and place paper and kindling on the grate for starting the fire.

3.Light fire and close feed door.

4.Add about 15 pounds of coal de- pending on model after fire is burning briskly. Use care not to smother the kindling fire. Set higher or lower for your comfort.

5.Set thermostat for desired tempera- ture.

ADDING FUEL

When starting a fire, add small amounts of fuel periodically as required (enough to burn for 3 to 5 hours). As you become more familiar with the operation of your heater, it is possible to add coal to burn for longer durations of between 8 to 12 hours, but doing so carelessly will pro- mote incomplete combustion and con- siderable sitting, along with a very dirty inefficient fire.

1.Set thermostat to HIGH before open- ing feed door.

2.Coal Fire- Never smother the fire when adding coal (see CAUTION be- low). Gas accumulation and a mild smoky explosion will occur:

a.Add fresh kindling if the bed of coals has cooled.

b.Add up to 20 lbs. of coal. Never add coal above top of the firebrick.

c.Stir the coal and watch the fire. Be sure the new coal is burning before you close the doors and turn the thermostat down.

3.Shake Grates vigorously back and forth to dump ashes into ash pan. Do this at least once every 12 hours of operation.

4.Empty ash pan regularly. Do not allow ashes to build up to grate, as grate will warp and burn out, and you might spill the ashes when removing the pan. Dispose of hot ashes properly. (See note 11 on page 3)

CAUTION: BUILD A FIRE ON INTE- GRAL GRATE THAT IS PROVIDED WITH THE HEATER.

MINIMUM FIRE

The burning rate at the low setting can be further adjusted by opening or clos- ing the minimum fire air shutter (Fig. 9) on the draft control door.

1.Partially close the shutter to make the fuel burn longer.

2.Open the shutter, exposing a large opening, to reduce the formation of creosote on soot (see notes on Chim- ney Maintenance).

3.Do not operate the heater with the minimum fire air shutter completely closed.

CAUTION: DO NOT OVERFIRE THE HEATER, AS STATED EARLIER, THIS CAN PRODUCE A DANGEROUS CONDITION AND EVEN CAUSE A HOUSE FIRE. IF ANY PORTION OF THE HEATER OR ANY CHIMNEY CONNECTOR GLOWS RED OR DIS- COLORS, THE HEATER IS BEING OVERFIRED.

CAUTION: DO NOT OPERATE THIS HEATER WITH FEED OR ASH DOOR OPEN. THIS HEATER IS DESIGNED FOR THERMOSTATIC OPERATION. OPERATION WITH EITHER DOOR OPEN WILL OVERHEAT AND DAM- AGE THE HEATER.

CAUTION:NEVER STORE FLAM- MABLE LIQUIDS, ESPECIALLY GASOLINE, IN THE VICINITY OF THE HEATER.

CAUTION: GASES THAT ARE DRIVEN FROM FRESH COAL MUST BE BURNED OR THEY WILL ACCU- MULATE AND EXPLODE. NEVER SMOTHER A FIRE WHEN ADDING FRESH COAL.

CAUTION: NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR "FRESHEN UP" A FIRE IN THE HEATER.

ADJUSTING THE THERMOSTAT

The thermostat control was calibrated at the factory. The operation of the heater may require a change in calibration. Calibration adjustments should be made at room temperature.

If the room temperature is not satisfac- tory, the thermostat operating range may be changed as follows:

A. To increase the amount of heat at a "HIGH" setting, adjust the wire link- age to increase the draft damper opening (Fig. 9).

1.Unhook linkage wire at point C

2.Take point A in left hand and B right hand then turn B clockwise about 3 turns.

3.Then hook linkage wire back to draft control damper door at point C.

B.To decrease the amount of heat at "LOW" setting:

1.Check feed and ash doors to be sure that they are closed tightly.

2.Check the connector pipe to see that it is sealed in the flue collar and at all joints.

3.If no air leaks are found, adjust linkage the same as above, except turn B counterclockwise about 3 turns.

CAUTION: NEVER USE THE MANU- FACTURED COAL BRICKS THAT ARE MADE FROM COAL DUST AND A WAX-TYPE BINDER.

WARNING: THE USE OF WOOD IN THIS STOVE EXCEPT FOR COAL IG- NITION PURPOSES, IS A VIOLATION OF FEDERAL LAW.

NOTE: More than one recalibration may be necessary. At room temp. (72*F) and "Low" setting, the draft damper door should be closed.

C. Adjusting the minimum Air Shutter: The minimum air shutter has an infinite number of settings. Several adjustments may be necessary for the unit to work most effectively for your particular installation.

1.The minimum air shutter may be adjusted to the closed position in installations where the draft is "above normal". Generally, .06 w.c. or above would be consid- ered "above normal".

2.In installation where the draft is "below normal", the minimum air shutter would be adjusted toward the open position.
