10 BASIC FUNCTIONS OF ELECTRICAL SYSTEM

1.Wall mounted thermostat requests heat...electrical contact occurs.

2.Current is sent through relay, rheostat, 170 degrees thermo limit disk to activate draft fan.

3.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.

4.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.

5.110 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)

6.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-

7.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-

8.tivate distribution fan.

Varistor: Provides even flow of current to snap disk,

9.prevents electrical surges, provides longer life of snap disk.

Transformer: Reduces voltage 110 volts to 12 volts for

10.thermostat usage. Generally hums a bit.

The above is somewhat basic, however, it's offered so you can understand your furnaces electrical functions and en- joy it more.

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.

NOWPROCEEDWITHLIGHTINGAFIRE.

1.Pull bypass damper out (opens up flue hole).

2.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.

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.
