Electrical wiring must be in accordance with the latest
edition of the National Electric Code
®
(NEC
®
), ANSI

unless local code requirements indicate otherwise.
The heater comes factory-wired intended for use with 240
Volt, 60 Hz AC field electrical supply. To use 120 Volt,
60 Hz AC requires changing the position of the voltage
selector board on the power distribution board. This must
be done by a certified electrician only, as with all wiring.
Be sure that the power source to the heater is turned off or
disconnected before servicing.
NOTE
If the heater is converted to accept 120V, the “Hot”
wire of the 120V power supply has to be connected to
the black wire (ACH1) on the power distribution board
and the “Neutral” wire of the 120V power supply has
to be connected to the red wire (ACN1) of the power
distribution board.
To wire the heater to 120V or 240V/60 Hertz (Hz):
1.
Remove the front door panel of the heater.
2.
Connect the wires from the power source to the
leads on the heater (Figure 21).
NOTE
No external junction box is required.

system is turned off before approaching, inspecting, or
troubleshooting any leaking plumbing that may have
caused electrical devices in the surrounding area to
get wet.
The heater is configured at the factory to operate at 240
VAC, 60 Hz; to convert.the heater to 120 Volt, 60 Hz
AC, reverse the voltage selector board on the power
distribution board before the heater is connected to a
power source:
To convert the heater to 120V 60 Hertz (Hz):
