Wall mounted thermostat requests heat...electrical
contact occurs.
Current is sent through relay, rheostat, 170 degrees
thermo limit disk to activate draft fan.
Relay...electrical switching device,
Rheostat...current (voltage) reducer increases or de-
creases draft fan R.P.M.
170 degrees limit disk...breaks off electrical current at
170 degrees (limit disk)
Draft fan...small fan that activates fire, increasing fire
temperature.
Upon firebox temperature rise due to air from draft
fan, distribution fan is activated at approximately 110
degrees air temperature, 600 CFM of air at 110 de-
grees.
110 volts (main electrical line) is sent to left side of 140
degrees thermo disk (3 prongs) current passes through
140 degrees disk to 110 degrees disk. Current simply
waiting for 110 degrees so it can pass through and
activate normal speed function of distribution fan. (blue
wire)
If 110 degrees firebox air temperature is not main-
tained snap disk terminates current to distribution fan.
Should firebox temperature air reach 140 degrees cur-
rent is directed to activate high speed portion 1300
CFM of air. Current travel from prong 1 to prong 2 on
140 degrees disk to activate high speed portion (black
wire).
Distribution Capacitor: Reduces amps required to ac-
tivate distribution fan.
Varistor: Provides even flow of current to snap disk,
prevents electrical surges, provides longer life of snap
disk.
Transformer: Reduces voltage 110 volts to 12 volts for
thermostat usage. Generally hums a bit.

Your new furnace is now completely assembled and ready
to be installed. Make sure you followed the sections on
installation in the front of this manual.
OPERATION OF YOUR NEW
WOOD BURNING FURNACE.
Check that your draft blower is in working order before
lighting a fire (cover setting 20% open).
Do this by turning the room thermostat to a high tempera-
ture so that the draft blower turns on, then turn the ther-
mostat back to proper setting thus turning the draft air
blower off. Should draft blower not function, check to see
if rheostat setting is on.
NOW PROCEED WITH LIGHTING A FIRE.
The above is somewhat basic, however, it's offered so you
can understand your furnaces electrical functions and en-
joy it more.
CAUTION:
Never use chemicals or fluids such as gasoline, char-
coal lighter fluid, drain oil or kerosene to light a fire in
your furnace. This would be like checking the level of
gas in your car with a lighted match.
10 BASIC FUNCTIONS OF
ELECTRICAL SYSTEM
Make sure your flue pipe damper is open. Place sev-
eral pieces of crumpled paper in the center of your
firebox. In a crisscross pattern, place a couple of hand-
fuls of dry kindling wood, then several small dry pieces
of firewood.
