Operating Instructions

FUEL
Models 1357M & 1557M
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.
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.
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. Gases from the accumulation smoke will explode
under certain conditoins. 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.
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.
