with a wall thermostat, operates the distribution blowers
	6. The motorized draft cycles (opened & closed) on demand
and the motorized draft on the front of the furnace. The
limit control is located on the rear of the furnace in the	from the wall thermostat. Setting the U.S. Stove thermo-
upper left corner and is accessible by removing the two	stat four degrees higher than your existing thermostat is
screws in the cover plate. DO NOT operate your furnace	recommended. In operation, the power draft will remain
with this plate removed! The control can be adjusted to	open until the U.S. Stove thermostat temperature setting is
your desired blower On/Off times. The factory settings are	reached. Then it will close to reduce combustion air. If the
100/150/200.	furnace looses power, the draft will automatically close.

The wall thermostat setting operates the ON time of the motorized draft. If the temperature is below the setting on the wall thermostat, the motorized draft will come open. (Recommended setting at 5 to 10 degrees higher than other heating thermostats.)

The first two set points on the limit control operates the distribution blower. When the furnace plenum reaches the second set point on the limit control, the distribution blower will come on. If the temperature falls to the first set point, the distribution blower will shut-off. The distribu- tion blower is a three speed blower and can be manually adjusted by means of the three position switch located behind the sliding access panel on the cold air return box.

When the furnace reaches the third set point on the limit control, the draft blower will shut-off. The draft blower will come back on if the temperature falls below the setting on the wall thermostat.

TESTING

1.Check the motorized draft by turning the room thermo- stat up high enough so that the motorized draft opens. Then lower the thermostat setting to ensure it closes off.

2.Use a sheet of newspaper to test your draft by placing it inside the furnace and lighting it.

With completion of the tests above, you are ready to light the furnace. Follow the operating steps.

STARTING A WOOD FIRE

Using Motorized Natural Draft

CAUTION: Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in the furnace. Keep all such liquids well away from the furnace while it is in use.

1.Open spin draft cap on ash door.

2.Pull the slide baffle rod to the front position.

3.Open the fuel load door and light fire using kindling and several sheets of newspaper, then close the furnace door. The furnace door should remain closed for 5 to 10 minutes in order to establish the fire. If the fire has established, you are ready to load the furnace.

CAUTION: To prevent flame and smoke spillage, the slide baffle must be pulled out and the fuel door must be cracked for ten seconds before being fully opened.

Do not over fire your furnace! After you have become familiar with its operating, you should know how much wood to use.

CAUTION: To avoid excessive temperatures, do not operate with fuel door or ash pan open.

STARTING A COAL FIRE

Shut off FAD when fuel door is open

Open all draft controls on your furnace. Pull the slide baffle forward.

Place about 10-15 lb. of coal in on the shaker grates. It should come up to about half of the first firebrick level.

Place crumpled paper over the coal and crisscross a couple handfuls of dry kindling wood 3/4” in thickness on top of paper.

Ignite the paper and close loading door. Wait about 30 minutes until coal fire is established before adding more coal. NOTE: NEVER load coal over the level of firebrick.

Close by-pass damper and set all draft controls to your own needs. It may take 3 to 4 coal fires to determine how your local coal and the Clayton Furnace reacts together. Adjusts drafts accordingly.

When loading with a good bed of coals in the morning - Open by-pass damper.

1.In normal shaking, only rock the grates a small amount to sift ash through. Do not agitate the fire bed too often. This practice will waste coal. If glowing coal is visible in the ash pan, you have shaken to much.

2.Remove all ashes every day from ash pit.

CAUTION: Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground well away from all combustible materials pending final 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.

3.With your poker, push hot burning embers to the rear of the unit and add green coal in front. NEVER load over height of firebrick. This can result in damage to your furnace and home.

4.Close by-pass damper.

Too much draft air will cause clinkering of coal and will waste heat up the chimney. Shut draft down to as low a point as you can and still heat your home.

1.NOTE: Never stand in front of loading door when opening it. Stand to the side.

2.NEVER completely cover the live fire with fresh coal. Always leave a generous area of glowing coal at the top of the fire and at the rear.

3.Always keep the ash pit clean.
