Welcome. My name is XXXXX XXXXX would be glad to assist.
Please be advised. The unit can be connected to 120 volts for operation
but in doing so, you must take other steps or possible damage to the heater
will result.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 rewiring of the
heater. To wire the heater for 120V,
60 Hz AC, follow the alternate 120V wiring method
depicted in Figure 16. Additionally, the ignition
control module must be rewired. The wire from the
terminal marked IGN/240 must be removed and placed
on the terminal marked IGN/120.
To wire the Legacy Model LRZ electronic heater
to a 120V or 240V /60 Hertz (Hz) electrical source:
1. Remove the door of the heater.
2. Connect the wires from the power source to the
leads on the right side of the heater in the space
behind the raceway. See Figure 15.3. Connect a bonding wire (8ga copper) to the
bonding lug on the right side of the heater
The heater must include a
definite means of grounding. There is a bonding lug on
the right side of the heater, where a bond wire must be
attached.Please see Page 21 and 22--CLICK HERE for the changes that MUST be done before connecting to 120 volts.
Also, the bonding must be performed to connect to the bonding grid as well for safety of the operation to prevent electrical shock hazards
