Flue Draft
The flue draft must be -.03” W.C. to -.05”W.C. If the -.05”W.C. is exceeded a power failure situation could
cause a solid fuel fire to burn out of control.
BURNING WOOD
See pages 10 - 12 for the best types of wood to burn.
In order to increase the capacity of the boiler firebox for burning wood, the grates may be removed, the
base lined with firebrick as shown in diagram #1, and the fire built directly on the firebrick floor of the unit.
Grates are required when burning coal but wood burns more efficiently without grates.
Turn the control box toggle switch marked Oil to “Automatic” and the toggle switch marked “Wood Only”
this will start the combustion air draft fan. During the initial start turn the draft fan off by means of the
switch located on the fan itself. Place paper and wood kindling in the firebox and ignite it. Once the wood
begins to burn, start the draft fan by turning the switch located on the fan to the “On” position. Once a
good base fire is established fill the firebox with wood. After the water temperature reaches 170ºF turn
the control box toggle switch marked “Wood” to Automatic. Automatic position allows the oil burner to
come on if the wood fire (because of not being adequately charged) permits the water temperature to
drop below 170ºF.
*A small intense fire is preferable to a large smoldering fire, to reduce the buildup of creosote.
