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.

4.Load the furnace, close the load door and push the slide Baffle rod to rear.

5.Close the spin draft cap on ash door, leaving it cracked about the diameter of a dime.

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.
