United States Stove 1800 Furnace User Manual


 
2. NEVER completely cover the live fire with fresh coal.
Always leave a generous area of burning coal at the top
of the fire and at the rear.
3. Always keep the ash pit clean.
If the fire goes out or does not hold overnight, look for:
1. Poor draft.
2. Incorrect damper settings.
3. Improper firing methods for coal being used.
4. More combustion air needed.
5. Coal not sized to the furnace. We recommend 1" to 3"
diameter pieces of coal.
6. Ashes, if allowed to accumulate in the ash pit, will not allow
the passage of required air for combustion. Keep ash pit
clean.
7. This furnace is not to be used with an automatic stoker
unless so certified.
OPERATING NOTES
Do not over draft the furnace! It is designed to operate at .06
inches of water column and must be set with a draft gauge to
maintain a steady draft. (Barometric Damper recommended.)
Do not allow ashes to build up higher than 2" above grates.
Be extremely careful when removing furnace ash pan; it can
get very hot.
With new steel, there is a small amount of oil or dirt on the
metal. You may smell an odor. This is normal during the first
operation. You may want to assemble the furnace out of doors
and build a small fire in it to "burn off" this dirt and oil
before installing the unit.
The furnace is designed to burn air dried wood and coal at a
predetermined firing rate. Over firing could result in damage
to the heat exchanger and cause dangerous operation. Over
firing occurs when the ash door is left open during operation
or a highly volatile fuel, i.e. large amounts of small kindling,
is used.
When tending the firebox always pull the baffle slide rod out
prior to opening load door. Open load door slowly to avoid a
"flash back". After closing load door, push the baffle slide rod
to the rear.
Equip your home with fire extinguishers and smoke
detectors appropriately located.
Inspect air filters regularly. The air filter in the filter box
should be changed at least every 30 days.
Oil motor on forced air draft every 90 days with a few drops
of 30 wt. oil.
The distribution blower motor motor may be one of two types.
If the motor has sealed bearings, no oiling is required.
If the motor is equipped with fill holes, the motor should be
oiled every 90 days with several drops of 30 wt. oil.
Check the fit on the load door. It must fit tightly. If it does not,
check for deterioration or wear of the ceramic rope seal.
Replace defective seals.
Inspect and clean your chimney and stove pipe regularly.
In event of chimney fire, shut all draft controls and call your
fire department immediately. Alert everyone in the house. If
the fire is still burning vigorously, throw baking soda into firebox
or discharge a fire extinguisher into the firebox. After chimney
fire is over, completely inspect system for damage before
further use.
Slow fires: It is not recommended burning the U.S. Stove
furnace any more than necessary early in the fall and late
spring, as you cannot keep the firebox hot enough (without
overheating your home) to burn gases. Slow fires can
cause excessive creosote build-up in smoke pipe, chimney
and firebox.
Wood should be placed directly onto the cast iron shaker grate
of the U.S. Stove furnace. Do not use additional grates and/or
irons.
In the event of a power failure, you may operate the 1600/1800
furnace provided the following instructions are followed:
1. Any air filter should be removed.
2. If the motorized natural draft is used, the draft cap is to
be set at a 1/2 inch opening. If the forced air draft is used,
the damper on the built-in draft regulator will automatically
open to the preset factory spacing.
3. Do not burn garbage, plastics, gasoline, drain oil or other
flammable liquids. Plastics, when burned, form hydrofluo-
ric and hydrochloric acids which will damage and destroy
your furnace pipe and chimney. The burning of trash or oil
can result in an extremely hot fire and is sometimes a
cause of chimney fires.
NEVER BURN GREEN WOOD OR TIRES.
Do not store fuel or other combustible material within marked
installation clearances.

cation "Using Coal and Wood Stoves Safely." NFPA NO. NW-8-
