DISCLAIMER NOTICE
e BTU ranges and heating capacity specications are provided
as a guide and in no way guarantee the output or capacity of
this unit. e actual BTU output depends on the type of fuel be-
ing burned and its conditions, the thermostat setting, the dra
adjustment and the chimney to which the unit is attached. e
actual area that this unit will heat depends on factors such as
the conditions of the building, heat loss, type of construction,
amount of insulation, type of air movement, the location of the
unit and more importantly the duct work and return air facility.
Warning: Do not alter this appliance in any way other than speci-
ed in these instructions. Doing so may void your warranty.
GENERAL NOTES
• Equip your home with re extinguishers and smoke detec-
tors appropriately located.
• e furnace is designed to burn air dried wood and coal at a
predetermined ring rate.
• Do not burn garbage, gasoline, naphtha, engine oil or other
inappropriate materials. Plastics, when burned, form hydro-
uoric and hydrochloric acids which will damage and de-
stroy your furnace pipe and chimney. e burning of trash
or oil can result in an extremely hot re and is sometimes
a cause of chimney res. NEVER BURN GREEN WOOD
OR TIRES.
• Solid-fuel burning appliances need to be cleaned frequently
because soot, creosote, and ash may accumulate. Establish
a routine for storage of fuel, ring techniques, and care for
the appliance.
• Keep Ash and Fuel loading doors closed during operation.
Check the t on the load door as it must t tightly. If it does
not, check for deterioration or wear of the ceramic rope seal.
Maintain all seals in good condition.
• Do not store fuel or other combustible material within
marked installation clearances or within the space required
for re-fueling and routine maintenance.
• Wood should be placed directly onto the cast iron shaker
grate of the furnace. Do not use additional grates and/or
irons.
• Slow res: It is not recommended burning the furnace any
more than necessary early in the fall and late spring, as you
cannot keep the rebox hot enough (without overheating
your home) to burn gases. Slow res can cause excessive
creosote build-up in smoke pipe, chimney and rebox. It is
better to keep a small, intense re as oppose to a large smol-
dering re. Be aware that the hotter the re, the less creosote
is deposited. Weekly cleanings may be necessary in mild
weather, even though monthly cleaning may be enough dur-
ing the coldest months.
• Inspect and clean your chimney and stove pipe regularly.
Check daily for creosote build-up until experience shows
how oen cleaning is necessary.
• Do not over dra the furnace! It is designed to operate at .06
inches of water column and must be set with a dra gauge to
maintain a steady dra. (Barometric Damper recommend-
ed.) If allowed to operate at a higher rate, it could cause a
solid fuel re to burn out of control.
• Never over re your furnace. Over ring could result in
damage to the heat exchanger and cause dangerous opera-
tion. Over ring occurs when the ash door is le open dur-
ing 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-ring situation.
Have a clearly understood plan for such a situation.
• In event of a chimney re, completely shut all dra controls
and call your re department immediately. Alert everyone
in the house. If the re is still burning vigorously, throw bak-
ing soda into rebox or discharge a re extinguisher into
the rebox. Aer chimney re is over, completely inspect
system for damage before further use.
• NEVER throw water on the re or at the furnace, as rapidly
expanding steam could result in a severe scalding.
• Do not allow ashes to build up higher than 2” above grates.
Never allow the ashes in the ash pan touch the grate section.
REMOVE ASHES FREQUENTLY!
• Be extremely careful when removing the furnace ash pan; it
can get very hot.
• CAUTION: Ashes should be placed in a steel/metal con-
tainer with a tight tting lid. e closed container of ash-
es should be placed on a non-combustible oor or on the
ground well away from all combustible materials pending
nal 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. Do
not place other waste inside this container.
• With new steel, there is a small amount of oil or dirt on the
metal. You may smell an odor. is is normal during the
rst operation. You may want to assemble the furnace out of
doors and build a small re in it to “burn o” this dirt and
oil before installing the unit.
• When tending the rebox always pull the bae slide rod out
prior to opening load door. Open load door slowly to avoid
a “ash back”. Aer closing load door, push the bae slide
rod to the rear.
• Inspect air lters regularly. e air lter in the lter box
should be changed at least every 30 days.
• Oil motor on forced air dra every 90 days with a few drops
of 30 wt. oil.
