10 Connecting Electricity
This appliance must be electrically grounded in
accordance with local codes, or in the absence of
local codes, with the National Electrical Code, ANSI/
NFPA 70. In Canada, the latest CSA C22.1 Electrical
Code.
Consult a qualified electrician for the electrical
work.
10.1 Water Heater
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Verify proper operation after servicing.
Electrostatic discharge can affect electronic
components.
Take precautions to prevent electrostatic
discharges from personnel or hand tools
during the Water Heater installation and
servicing to protect products electronic
control.
CAUTION
Electrical Shock Hazard
Do not connect the electrical power to the
appliance until all electrical wiring has been
completed.
Failure to do so may result in death or serious
injury from electrical shock.
WARNING
10.2 Remote Controller
Install the Remote Controller according to the
instructions on page 45-48.
Only one the Remote Controller can be connected
to the Water Heater.
A malfunction may occur if two or more Remote
Controllers are connected.
Install according to the National Electrical Code
and all applicable local codes.
For extensions, a 26 ft (7.9 m) cord can be
purchased separately (Part #RC-CORD26).
The Remote Controller Cord can be extened up
to 300 ft (91 m) by splicing the cord and using 18
AWG wire to extend the cord to the appropriate
length.
Use a Y-shaped terminal with a resin sleeve.
Without the sleeve, the copper wire may corrode
and cause problems.
Breaker Installation
Mount a device which shuts off the electrical path
automatically (leakage breaker) to detect electrical
leakage.
Power Supply
The electrical supply required by the Water
Heater is 120 VAC at 60 Hz.
The power consumption may be up to 210 W or
higher if using optional accessories.
Use an appropriate circuit.
Tie the redundant power cord outside the Water
Heater. Putting the redundant length of cord
inside the Water Heater may cause electrical
interference and faulty operation.
NOTE
Do not let the power cord contact
the gas piping.
Do not disconnect the electrical
power when not in use. When the
power is off, the freeze prevention
in the Water Heater will not
activate, resulting in possible
freezing damage.
