ELECTRICAL WIRING

The whole wiring from the distribution panel to the heating unit shall comply with the applicable electrical
standards and local codes. The unit should be connected to its own 15 amp/120VAC electric circuit (see
electrical diagram on page 18).

THERMOSTAT

Both the wood and oil thermostats must be installed side by side on an interior wall, in a location where
they are not affected by the air draft coming from the furnace's blower; they must be level and at least 55
inches above the floor.

FAN CONTROL

The oil fan limit control settings may vary depending on the type of building and heating installation. The
"fan off" temperature is factory set at 100
physically possible to the "fan" off" setting; the high limit is set at 250° and these settings should allow
proper operation in most installations.
In order for the blower to run for long enough periods, the "fan off" setting must not be set too high but
too low a setting will result in undesirable cold air circulation. To modify this setting, turn the indicator to the
desired position on the temperature scale of the fan limit control.
All adjustments of the controls must be performed by a qualified technician. The controls settings and the
blower speeds must be set in accordance with the recommendations of the Warm Air Heating and Air
Conditioning National Association.
To obtain a continuous air circulation during summer months, simply use the red manual switch located
on the cover of the junction box which controls the low speed in either "on" or "off" position.
It is not recommended to let the blower run on continuous mode when heating with wood as the wood
furnace must reach a certain temperature before the blower starts to perform adequately.
o
F and the "fan on" setting should be positioned as close as
