Paloma PH2-20 Direct Vent - Manual (Page 21)

Electrical Connection
POWER CORD:
The electric power supply requirement
for this water heater is 120 VAC/60HZ,
2 Amps.
The water heater comes with a three (3) pin
power supply cord. Use only a power outlet
with a ground terminal.
The installation of an GFCI (Ground Fault
Circuit Interrupter) is recommended.
Keep any excess of the power supply cord
on the outside of the water heater.
If local codes require hardwiring, see
instructions for “Hardwiring the Electrical
Connections”
NOTICE: Do not connect power until
venting installation is complete. (See Venting
installation pages 9-14.)
NOTICE: Wait ninety (90) seconds after
power connected for the first time to initiate
operation of the water heater.
HARDWIRING
THE ELECTRICAL CONNECTIONS:
Wiring should be carried out by a qualified
electrician in accordance with local codes.
The water heater requires 120 VAC/60Hz and
should be properly grounded.
DO NOT connect grounding wire to water
pipes, gas pipes, telephone cables, lightning
conductor circuits and to grounding circuit
of other equipment that carry a ground-fault
interrupter.
An ON/OFF switch must be provided and
installed for the incoming 120VAC power.
Wire the water heater exactly as shown
below. A wiring diagram is also found
inside of the cover panel.
A green screw is provided in the enclosure
for a grounding connection.
Connect the live wire to black leg wire and
the neutral wire to the white neutral wire.
WARNING: Shock
hazard line voltage is
present. 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
could result in severe
personal injury or death.
CAUTION: Label
all wires prior to
disconnection when
servicing controls. Wiring
errors can cause improper
and dangerous operation.
Verify correct operation
after servicing.
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, CSA C22.1 Part 1.
