After heater has been properly mounted to the building structure and
appropriate branch circuit wiring has been routed to the heater location in
accordance with the National Electrical Code and local codes, the heater is
now ready for the heater to be connected to the branch circuit.
WARNING
Risk of Electric Shock or Fire
Make sure electric power is disconnected at main electrical panel before
attempting to connect heater to branch circuit. Verify branch circuit
voltage is same as noted on heater nameplate. Connecting heater to
a voltage greater than the heater nameplate rating could damage the
heater and cause a fire.
Heater is provided with a 7/8” (22mm) hole into wiring compartment for
routing of branch circuit conductors. Appropriate conduit and fittings must be
provided for correct and safe installation.
1.
Remove the field wiring cover located on bottom of heater by removing
two screws. See Figure 8 and Figure 9 for reference.
2. Bring branch circuit conductors to heater and into wiring compartment
allowing approximately 6“ (153mm) of wire inside heater compartment
for wire connections. Install appropriate cable fitting into the heater as
shown in Figure 10 and Figure 11.
3. Following the wiring diagrams in Figure 12 connect the supply wiring to
the heater lead wires inside the wiring compartment.
