Firing The Furnace

Alarm, see E.T.C. Section) press set on Dixell. Paper and kindling should be used for starting the fire. Build a
small fire, turn fan switch to on, and close fuel door. Be sure that the pumps are circulating when firing the fur

nace. Add wood as needed to increase water temperature to 170°F. Once the furnace has reached 170°F, the
furnace is ready to be filled to capacity to operate for a 12 hour period.
Rotate ash from back to front, maintaining a level coal bed. Load wood towards the back of the furnace for
improved efficiency. WoodMaster recommends burning cut, split and seasoned wood. Do not overfill so that
hot coals fall out of the furnace when opening the fuel door. During periods of warmer weather, you may find
it to have creosote inside the firebox. It is important to fill the furnace only with enough wood to last up to a
12 hour period. After burning your furnace for a period of time, you will discover how much wood is needed
per day and what types of wood burn the best.
Loading the Furnace
When loading your furnace the manufacturer recommends that you center your wood lengthwise in one row
as shown below. This will allow air from the draft fan to circulate properly creating the optimum burn
environment.

contributing factors that will determine how much wood is needed.
