MOVE ASHES FREQUENTLY!
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 pre
-
determined 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. If any portion of
the connector pipe glows orange or red, you are in an over-firing
situation. Close all dampers.
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 ap
-
propriately 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 motors 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 de
-
partment 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.
NEVER throw water on the fire or at the furnace, as rapidly expand
-
ing steam could result in a severe scalding.
Slow fires: It is not recommended burning the 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
furnace. Do not use additional grates and/or irons.
In the event of a power failure, you may operate the AAF747 furnace
provided the following instructions are followed:
1. Any air filter should be removed.
2. Observe the furnace operation closely and often till power is
restored.
Do not burn garbage, plastics, gasoline, drain oil or other flammable
liquids. Plastics, when burned, form hydrofluoric 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 instal
-
lation clearances.
NOTE: For further information on using your furnace safely, obtain
a copy of the National Fire Protection Association publication “Using
Coal and Wood Stoves Safely.” NFPA NO. NW-8-1974. The address of
the NFPA is 470 Atlantic Ave., Boston, Massachusetts 02210.
OPERATING NOTES
THIS IS A WOOD AND COAL BURN-
ING FURNACE AND SHOULD NOT BE
ALTERED IN ANY WAY! DOING SO
WILL VOID YOUR WARRANTY!
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.
There are ONLY two types of coal allowed for use in this furnace:
Bituminous Coal (soft coal) and Anthracite Coal (hard coal). NEVER
USE Cannel (or Channel) coal or Brown (Lignite) Coal.
See our Bulletin RC454 at the rear of this manual for the best infor
-
mation available on burning coal.
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.
Never allow the ashes in the ash pan touch the grate section. RE
