Connect Electricity
WARNING
Do not use an extension cord or an 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.
Do not rely on the gas or water piping to ground the
water heater. A screw is provided in the junction box
for the grounding connection.
The water heater requires 120 VAC, 60 Hz power from
a properly grounded circuit.
If using the 5 foot long power cord, plug it into a
standard 3 prong 120 VAC, 60 Hz properly grounded
wall outlet.
On outdoor models, a disconnect switch must be
provided and installed for the incoming 120 VAC
power. It 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.
The wiring diagram is located on the Technical Sheet
attached to the inside of the front cover.
