Electrical Wiring - Rheem RTGH-95DVELN-3 Use And Care Manual

Gas Supply
High-Altitude Installation
The water heater is certified for installations up to
7,800 ft. (610 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 due to the
derating of Natural Gas and LP Gas.

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, or in Canada, Canadian Electrical Code, CAN/CSA
C22.1, Part 1.
CAUTION:
Label all wires prior to disconnecting 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).
• 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.
INSTALLATION INSTRUCTIONS
NOTICE:
For installations above 2000 ft. (610 m) elevation, contact
a qualified service technician to make the proper altitude
adjustments. See "Vent Length and High-Altitude DIP
Switch Adjustments" for additional information.
WARNING:
DO NOT install this water heater at elevations above 2000
ft. (610 m) without the proper adjustments. Please contact
your installer, local gas supplier, place of purchase, or the
Rheem Customer Service phone number listed in the "Call
for Assistance" section.
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 3-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 dedicated 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.
