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.
NOTICE:
• 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
!
WARNING:
DO NOT install this water heater at elevations above
2000 ft. (610 m) without the proper adjustments.
Failure to install a water heater suitable for the
altitude at the location it is intended to serve
can result in improper operation of the appliance
resulting in property damage and/or producing
carbon monoxide gas, which could result in
personal injury or death.
NOTICE:
For installations above 2000 ft. (610 m) elevation,
contact a qualified service technician to make the
proper altitude adjustments. You can also contact
your local gas supplier, place of purchase, or call
the Rheem Customer Service phone number listed
on page 26 in the "Call for Assistance" section.
See pages 70 and 71 for additional information.
