WARNING
•
Do not use an extension cord or adapter plug with this appliance.
•
The water heater must be electrically grounded in accordance with local codes and ordinances or, in the absence
of local codes, in accordance with the National Electrical Code, ANSI/NFPA No. 70.
•
Indoor water heaters are equipped with a three-prong (grounding) plug for your protection against shock hazard
and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the
grounding terminal from this plug.
Guidelines
When connecting the power supply, follow these guidelines:
•
Do not rely on the gas or water piping to ground the water heater. Ground locations are provided inside the water
heater.
•
The water heater requires 120 VAC, 60 Hz power from a properly grounded circuit.
•
If using the 5 ft (1.5 m) power cord (supplied with internal/indoor water heaters), plug it into a standard 3 prong
120 VAC, 60 Hz properly grounded wall outlet.
•
On external (outdoor) models, a disconnect switch must be provided and installed for the incoming 120 VAC
power. The switch should be a type that is suitable for outdoor use. Check the National Electrical Code, ANSI/NFPA
70 and your local codes for a proper switch type to use in your area. Power connections must be protected from
the weather and flexible cords must use an appropriate strain relief.
•
The wiring diagram is located on the inside of the water heater front cover.
