Fuel Requirements
BURN AIR-DRIED WOOD, OR ANTHRACITE OR BITUMINOUS COAL ONLY
It is important to use fuel that is clean, dry and consistent. Solid-fuel Furnaces, such as your
ENERGY KING Wood/Coal Furnace, naturally produce ash as a byproduct of the burning process.
Even with the ENERGY KING Furnace’s efficient design, your Furnace will still produce some
amount of ash which will need to be cleaned periodically. The type and quality of fuel you burn
affects the amount of ash produced and the performance of your Furnace. To assist you in
determining which fuel to use, here are some guidelines to consider:
WOOD
Burning wood for heat is as old as civilization itself. More than any other major fuel, wood provides
us with energy independence – an easily available, locally produced and renewable source of heat
on which we can rely.
This Furnace has been tested for operation
with air-dried wood.
Wood should be seasoned (dried) for at
least 12 months before burning. Properly
seasoned wood should have about 20% -
30% moisture content. To properly season
wood, split the logs as soon as possible
and loosely stack them in a dry spot for at
least 12 months.
You should not burn wet or green wood in
your Furnace. Burning wet or green wood
in your Furnace will not only reduce the
efficiency of your appliance, but also
increases the risk of dangerous creosote
build-up in your appliance and chimney.
Softwoods, such as pine and fir, are easily
ignited and burn rapidly with hot flames.
With softwoods, you will spend more time
reloading your Furnace, and will have much
more difficulty achieving an overnight burn.
For a longer lasting fire, it is best to use
more dense hardwoods.
Ideally, you should burn a mixture of
hardwoods and softwoods, using the hotter,
faster burning softwoods to start your fire,
and the denser hardwoods to maintain a
longer-lasting fire.
With this in mind, choosing the kind of
firewood that is best for you depends on
what is available in your area. If hardwoods
are unavailable in your area, you can
control the burn rate by using larger pieces
of wood and by adjusting your draft
controls.
DO NOT BURN: Treated wood, colored
paper, garbage, cardboard, solvents, or
trash—burning these may result in toxic
fumes, or produce soot and large flakes of
char or fly ash. Burning treated wood,
colored paper, garbage, cardboard,
solvents or trash can be dangerous and will
void your ENERGY KING warranty.
DANGER – Risk of Fire or Explosion: Do
not burn garbage, gasoline, naphtha, drain
or engine oil, or other flammable liquids or
inappropriate materials in this Furnace.
Storage
Store all fuel in a dry location away from
the elements. Never burn wet or green
wood.
Do not store fuel within the Furnace
installation clearances or within the space
required for refueling, ash removal and
other routine maintenance operations.
Risk of Fire: Do not store fuel or other combustible
material within the marked installation clearances.
