WIRING
1. To connect the power to the heater, simply remove
the screw from the front of the unit. This allows the
hinged bottom to open, providing access to the
electrical wiring and connectors. (See Figure 5)
2. Attach the cable connectors to the unit and slide
the 10 gauge or thicker wire through the cable
connector. (See Figure 1)
3. Pull enough wire through the connector to work with
when making the connections.
NOTE: Wiring compartment volume: 370 in
4. Connect the wire to the power terminal block
located in the base of the heater (See Figure 6).
NOTE: Unit is 240/208 volts. When wiring a two
conductor cable with ground, the white wire
must be marked black by adding a piece of
black electrical tape to the wire near the point
of connection.
NOTE: To decrease the heat output of the
heating unit, see Adjusting Heat Output below
and Figure 7.
WARNING! To prevent possible electric shock,
disconnect power to the heater at the main
service box before attempting to adjust the
heat output of this unit.
ADJUSTING HEAT OUTPUT
Heat output can be increased or decreased by switching
wires at the wattage change terminal board. The H-6517
is factory wired to deliver a heat output of 17,065 BTU per
hour. The H-6518 is factory wired to deliver a heat output
of 25,598 BTU per hour. For less heat output, refer to the
Heat Output Adjustments table and change the wires at
the wattage change terminal board as shown in Figure 7.
