MAINTENANCE AND OPERATING BULLETIN
The following are some suggestions with reference to the above:
1. MAINTENANCE - In addition to periodic cleaning, it is most important that the unit be cleaned thoroughly
at the end of each heating season. Both the primary and the secondary heat exchangers should be given
extra attention with a steel scraper 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 Multi-fuel 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 multi-fuel 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.
