FAN LIMIT CONTROL INSTALLATION ON MODEL PSG/UH-4500
The wood unit fan limit control must be installed with the mounting bracket in the warm air plenum on the
right hand side of the appliance (two holes are pre-drilled on the upper edge of the furnace to receive the
mounting bracket). The fan limit control for the oil burning unit must be installed on the upper right part of
the appliance's front panel (a 1" diameter hole is pre-punched in order to insert the fan limit's sensor in the
furnace).
N.B. On the PSG/UH-4500, the wood fan limit control is the one that is attached to the junction box and
relay-transformer.

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).

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.
