or brush. This will help to prevent rust and corrosion during the high humidity summer months. Also, if the firedoor
is left open, it will allow for air to circulate through the units.

2. OPERATION

a) When burning with wood, the minimum setting for the manual draft slide should be in the center. (This is the
slide knob beside the combustion fan above the firedoor). The closed position is for when burning with oil for a
prolonged period (to obtain maximum efficiency) and the open setting is for initially starting a wood fire.
b) Do not attempt to burn the solid fuel in the spring or fall when temperatures are mild. This will cause the unit to
be shut down for extended periods at a time and will form creosote and soot.
c) In the Multifuel units – two or three times a week, burn the oil fuel for an hour or so. This will help to keep the
unit clean of creosote build up.
d) In the Solid Fuel units – burn the fuel at maximum draft with good dry wood for an hour or so (once or twice a
week). This will help to prevent creosote build up.
e) During the off season, in order to dry out the humidity in the unit, fire the furnace once a month for at least 30
minutes.
The multifuel unit – use the oil side.
The solid fuel furnace – build a fire with dry wood.
The above details, if adhered to, will extend the longevity of your furnace and provide many years of warm,
comfortable heat.
