OWNER’S OPERATING INSTRUCTIONS
The S-150 energy saver Add-On is a wood burning
furnace designed to give you heat automatically to the
temperature you select on the room thermostat. The S-150
add-on is intended to be used as an add-on furnace used
in conjunction with and the duct work connected to your
existing oil-fired or gas-fired heating system.
The furnace requires hand firing and attention by you to
ensure satisfaction and safety in its operation.
Cautions
Burn wood only (unsafe to fire with coal).
Do not use chemicals or fluids to start the fire.
Never fire with treated wood, or burn garbage, gasoline,
naptha or engine oil.
Never load wood in firebox higher than half way up the
door.
Do not store combustibles within the minimum installa-
tion clearances.
Build a small intense fire at least once a day to reduce
creosote build up.
Clean chimney at least once a year, and inspect regularly
for creosote build up.
For safety keep fire charging door tightly closed.
Do not adjust electrical control settings or blower pulley
arrangement.
Operate the oil-fired or gas-fired unit periodically to en
-
sure that it will operate satisfactorily when needed.
Keep fire door closed and maintain all seals in good
condition.
Make sure adequate combustion air is provided in furnace
area.
The S-150 Add-On is not to be used with an automatic
stoker.
Firing
Star the fire in your wood burning furnace with paper and
kindling only.
Crumple a quantity of paper and place it in the bottom of
the fire box.
Randomly stack kindling on top of the paper allowing for
good combustion and air circulation.
Set your thermostat so that it is 7-10 degrees fahrenheit
higher than room temperature. This will open the draft
damper allowing combustion air into the furnace.
Light the paper and close the fire charging door.
When the kindling is burning well put in some hardwood
and allow this to begin burning.
Add hardwood;
Do not fill the firebox above the firing line (halfway up
the door). Do not put in too much wood at one time dur-
ing initial start-up as you could smother the fire.
When fire has been established properly, set thermostat to
your desired setting. The thermostat controlling the add-
on unit should be set at 5° above the oil or gas furnace
thermostat at 18° C (65°F) and the add-on unit thermostat
at 21°C (70°F).
Maintaining Fire
You will be required to maintain the fire in your wood
burning furnace manually.
The rate at which you have to charge your furnace will
vary with the size of house, type of wood and weather
conditions.
When the fire in your wood burning furnace is not great
enough to properly heat your home, the air circulation
blower fan in the oil-fired or gas-fired furnace will begin
to come on more frequently.
