5. Close the spin draft cap on ash door.
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 recom-
mended.
During operation, the motorized natural draft remains
open until the thermostat temperature setting is reached.
CAUTION: Hot Surfaces. Keep children away. Do not
touch while in operation.
TESTING:
1. Check the draft blower (optional) by turning the room
thermostat up high enough so that the draft blower turns
on. Then ower 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 Forced Air Draft (optional)
CAUTION: Never use gasoline, gasoline-type lantern fuel, kero-
sene, 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. Open spin draft cap on ash door.
2. Pull the slide baffle rod to the front position.
3. 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 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.
STARTING A WOOD FIRE
Using Manaul Natural Draft
CAUTION: Never use gasoline, gasoline-type lantern fuel, kero-
sene, 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 manual 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 slide
baffle rod to rear.
TESTING AND OPERATING PROCEDURES
CAUTION: Cleaning of the heat exchanger, flue pipe,
chimney and draft inducer, if used, is especially important
at the end of the heating season to minimize corrosion
during the summer months caused by accumulated ash.
CAUTION: Do not use chemicals or fluids to start the fire.
Shut off FAD when fuel door is open.
CAUTION: To avoid excessive temperatures, do not op-
erate with fuel door or ash pan open.
Shut off FAD when fuel door is open.
STARTING A COAL FIRE
If you burn coal a Forced Air Draft may be required.
Open smoke pipe damper all the way. Open all draft controls
on your furnace. 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.
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.
2. NEVER completely cover the live fire with fresh coal.
Always leave a generous area of glowing coal at the top
of the fire and at the rear.
3. Always keep the ash pit clean.
Shut off FAD when fuel door is open.
