United States Stove 1537G Operating Instructions, Set the thermostat on HIGH for maximum draft

OPERATING INSTRUCTIONS

FUEL, Model 1537G

A)Egg size (1-3/16" or larger) bituminous coal for residential furnaces, or any of the specially packed fireplace coals can be used. Coal with a low ash content (2% to 6%) is recommended.

B)Hardwood, 18" to 26" should be split and air dried (seasoned) for 6 months.

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 the fire and close the feed door.

4.Add wood or about 15 lbs. of coal (depending on which model) after fire is burning briskly. Set thermostat for desired temperature.

5."MEDIUM" setting is normally satisfactory. Set higher or lower for your comfort.

ADDING FUEL

When starting a fire, add small amounts of fuel instead of adding large quantities of fuel. This will give more complete combustion and less build-up of tars or soot in the chimney.

1.Set thermostat to HIGH before opening feed door.

2.Wood fire -

Add wood to a convenient level.

3.Coal Fire -

a.Never smother the fire when adding coal (See Caution). Gas accumulation and a mild smoky explosion will occur. Add fresh kindling if the bed of coals has cooled.

b.Add up to 20 lbs. of coal per loading. Never add coal above the bottom of feed door opening.

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

d.Shake grates vigorously 1/2" left to right to spill ashes into the ash pan. Do this at least once every 12 hours of operation. Empty ash pan regularly. Do not allow ashes to build-up to grate as grate will warp and burnout, and you might spill the ashes when removing the pan. Dispose of hot ashes properly (See note 12 on page 4).

e.Rotation of the handle (5 o'clock to 7 o'clock) position will agitate coals and spill ashes into ash pan.

f.It is advisable for you to get familiar with the shaker grate operation before firing.

CAUTION

GASES THAT ARE DRIVEN FROM FRESH COAL MUST BE BURNED OR THEY WILL ACCUMULATE AND EXPLODE. NEVER SMOTHER A FIRE WHEN ADDING FRESH COAL.

CAUTION

DO NOT OPERATE WITH THE FEED AND/OR ASH DOOR OPEN. THIS FURNACE IS DE- SIGNED FOR THERMOSTATIC OPERATION. OPERATION WITH ANY OF THESE DOORS OPEN WILL OVERHEAT AND DAMAGE THE FURNACE.

CAUTION

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

WARNING

NEVER STORE FLAMMABLE LIQUIDS, ES- PECIALLY GASOLINE, IN THE VICINITY OF THE FURNACE.

ADJUSTING BLOWER LIMIT CONTROL SET- TINGS.

The temperature in the plenum of the warm air furnace at which the blower turns on or turns off, is controlled by the setting of the pointers in the blower limit control (See Fig. 12). These pointers may be adjusted through their entire range of settings to achieve the desired warm air output from furnace. (See Fig. 15 below)

Move both pointers towards the right (counter clockwise) - this increases the temperature setting at which the blower will turn on and off. Move both pointers towards the left (clockwise) - this decreases the temperature setting at which the blower will turn on and off. Move pointers away or apart from each other- this increases the time that the blower will run on each warm air cycle.
