Electrical Wiring
DANGER:
Shock Hazard – Before servicing
the water heater, turn off the electrical power to the water
heater at the main disconnect or circuit breaker. Failure to
do so will result in death or serious personal injury.
WARNING:
Field wiring connections and
electrical grounding must comply with local codes or,
in the absence of local codes, with the latest edition of
the National Electrical Code, ANSI/NFPA 70, in the U.S.,
or Canadian Electrical Code, CAN/CSA C22.1, Part 1, in
Canada.
CAUTION:
Labeling all wires prior to
disconnection is recommended. Wiring errors can cause
personal injury, product damage, and/or dangerous
operating conditions. Verify correct operation after
servicing.
NOTICES:
•
DO NOT
connect power until venting installation is
complete (see Venting Installation pages 34–45).
• Wait ninety (90) seconds after power is connected for
the first time to initiate operation of the water heater.
• Power consumption is up to 100 Watts during normal
operation, 3-5 Watts during standby, waiting to run, and
up to 200 Watts during the freeze protection operation.
Power Cord
• The electric power supply requirement for this water
heater is 120 VAC/60 Hz, 2 Amps.
• A dedicated circuit is recommended for the water heater.
DO NOT
connect to a GFCI or AFCI circuit. Multiple
units may be connected to a single circuit up to the
circuit rating.
•
DO NOT
use 3-prong to 2-prong adapters.
DO NOT
use power strips or multiple outlet adapters.
• All direct-vent gas models come with a three-prong
power cord. Only use this power cord and a matching
grounded electrical outlet.
• All outdoor gas models do not come with a power cord.
Only hard-wire to an appropriate power outlet with a
ground terminal.
• Keep any excess length of the power supply cord on the
outside of the water heater.
• If local codes require hard-wiring, see instructions for
“Hard-Wiring the Electrical Connections” below.
Hard-Wiring the electrical Connections
• Wiring should be performed by a qualified electrician in
accordance with local codes.
• The water heater requires a properly grounded 120
VAC/60 Hz power supply. Multiple water heaters may be
connected to a single circuit up to that circuit’s rating.
• DO NOT connect grounding wire to water pipes, gas
pipes, telephone cables, lighting conductor circuits, or to
any other grounding circuits that
require a GFCI or AFCI (arc fault circuit interrupter).
• An ON/OFF switch must be provided and installed for
the incoming 120 VAC power supply.
• Wire the water heater exactly as shown in the wiring
diagram. This wiring diagram can also be found inside
the water heater cover panel.
• The green screw is provided in the enclosure for a
grounding connection.
• Connect the live wire to the black wire and neutral wire
to the white neutral wire.
High-Altitude Installation
The water heater is certified for installations up to 3,280
ft. (1,000 m) above sea level. The input rating of this
water heater is based on sea level operation. At higher
elevations, the actual input rate may be lower than the
value listed on the rating label.
NOTICE
:
• For installations above 3,280 ft. (1,000 m) elevation,
contact a qualified service technician to make the
proper altitude adjustments. See pages 66 and 67 for
additional information.
WARNING:
•
DO NOT
install this water heater at elevations above
3,280 ft. (1,000 m) without the proper adjustments.
Please contact your installer, local gas supplier, place
of purchase, or the Rheem Customer Service phone
number listed on page 26 in the “Call for Assistance”
section.
