established, you are ready to load the furnace.
CAUTION: To prevent flame and smoke spillage, the slide
baffle must be pulled out and the fuel door must be cracked
for ten seconds before being fully opened.
Do not over fire your furnace! After you have become familiar
with its operating, you should know how much wood to use.
4. Load the furnace, close the load door and push the
slide Baffle rod to rear.
5. Close the spin draft cap on ash door.
6. The forced air draft cycles on demand from the
wall thermostat. Setting the U.S. Stove thermostat four
degrees higher than your existing thermostat is
recommended. In operation, the power draft blower will
run until the U.S. Stove thermostat temperature setting
is reached. The draft regulator on the forced air draft is
preset at the factory and should require no adjustment.
CAUTION: To avoid excessive temperatures, do not
operate with fuel door or ash pan open.
STARTING A COAL FIRE
If you burn coal a Forced Air Draft is required.
✓ Open smoke pipe damper all the way. Open all draft
controls on your 1600/1800. Pull the slide baffle forward.
✓ Place about 10-15 lbs. of coal in on the shaker grates.
It should come up to about half of the first firebrick level.
✓ Place crumpled paper over the coal and criss-cross a
couple handfuls of dry kindling wood 3/4" in thickness on
top of paper.
✓ Ignite the paper and close loading door. Wait about 30
minutes until coal fire is established before adding more
coal. NOTE: NEVER load coal over the level of firebrick.
✓ Close by-pass damper and set all draft controls to your own
needs. It may take 3 to 4 coal fires to determine how your
local coal and the Hotblast Furnace reacts together —
adjusts drafts accordingly.
✓ Loading with a good bed of coals in the morning — open
by-pass damper.
1. In normal shaking, only rock the grates a small amount
to sift ash through.
2. Remove all ashes every day from ash pit.
CAUTION: Ashes should be placed in a metal container
with a tight fitting lid. The closed container of ashes should
be placed on a non-combustible floor or on the ground
well away from all combustible materials pending final
disposal. If the ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be retained in the
closed container until all coals have thoroughly cooled.
3. With your poker, push hot burning embers to the rear of
the unit and add green coal in front. NEVER load over
height of firebrick. This can result in damage to your
furnace and home.
4. Close by-pass damper.
✓ Too much draft air will cause clinkering of coal and will
waste heat up the chimney. Shut draft down to as low a
point as you can and still heat your home.
1. NOTE: Never stand in front of loading door when
opening it. Stand to the side.
TESTING:
1. If using an optional power draft, check the draft blower
by turning the room thermostat up high enough so that
the draft blower turns on. Then lower the thermostat
setting until you hear it shut off.
2. Use a sheet of newspaper to test your draft by placing it
inside the furnace and lighting it.
With completion of the tests above, you are ready to light the
furnace. Follow the operating steps.
STARTING A WOOD FIRE
Using Motorized Natural Draft
CAUTION: Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to start or
"freshen up" a fire in the furnace. Keep all such liquids well
away from the furnace while it is in use.
1. Turn up thermostat to open motorized damper.
2. Open spin draft cap on ash door.
3. Pull the slide baffle rod to the front position.
4. Open the fuel load door and light fire using kindling and
several sheets of newspaper, then close the furnace
door. The furnace door should remain closed for 5 to
10 minutes in order to establish the fire. If the fire has
established, you are ready to load the furnace.
CAUTION: To prevent flame and smoke spillage, the slide
baffle must be pulled out and the fuel door must be cracked
for ten seconds before being fully opened.
Do not over fire your furnace! After you have become familiar
with its operation, you should know how much wood to use.
4. Load the furnace, close the load door and push the

6. The motorized natural draft cycles on demand from the
U.S. Stove wall thermostat. Setting the thermostat
four degrees higher that your existing thermostat is
recommended.
During operation, the motorized natural draft remains
open until the thermostat temperature setting is
reached.
CAUTION: To avoid excessive temperatures, do not
operate with fuel door or ash pan open.
