Installing the water heater.
Electrical Connections
A separate branch circuit with copper
conductors, over current protective device
and suitable disconnecting means must be
provided by a qualified electrician.
All wiring must conform to local codes
or latest edition of National Electrical
Code ANSI/NFPA 70.
Canadian models must conform to local
codes or latest edition of Canadian
Electrical Code.
The water heater is completely wired to
the junction box inside jacket at the top
front of the water heater. An opening for
1/2″ or 3/4″ electrical fitting is provided
for field wiring connections.
The voltage requirements and wattage
load for the water heater are specified
on the rating plate on the front of the
water heater.
The branch circuit wiring should include
either:
Metallic conduit or metallic
sheathed cable approved for use as a
grounding conductor and installed
with fittings approved for the
purpose.
Non-metallic sheathed cable,
metallic conduit or metallic sheathed
cable not approved for use as a
ground conductor shall include a
separate conductor for grounding. It
should be attached to the ground
terminals of the water heater and the
electrical distribution box.
CAUTION: The presence of water
in the piping and water heater does
not provide sufficient conduction for a
ground. Non-metallic piping, dielectric
unions, flexible connectors etc. can
cause the water heater to be electrically
isolated.
