TRANSFORMER WIRING
120 VAC WIRING
The heater requires 5 amps of 120V/1ph/60Hz power.
To wire the 120V power supply to the heater, connect
the pair of black wires to the “L1” or hot leg of the
power supply. Connect the pair of white wires to the
“Ret” or neutral leg of the power supply. Attach the wire
nut to the red wire.
There should be no connection
to the red wire for 120 VAC operation.

The heater must be electrically grounded and bonded
in accordance with local codes, or, in the absence of
local codes, with the latest edition of the National
Electrical Code, ANSI/NFPA 70. (Canada - Canadian
Electrical Code, CSA C22.1, Part 1 and Part 2.)
WARNING:
The transformer’s primary side is
wired for 120 VAC and if 240 VAC is applied, dam-
age to the transformer and PC board may result.
Such damages are not covered under manufactur-
er’s limited warranty.
NOTE:
Input power to the heater (120 VAC) can
be supplied from the load (pump) side of time clock
or directly from the GFCI power source.
It is
required that full-time power be supplied to the
heater from the GFCI power source, and that
the heater be controlled by the fireman’s switch
connection or using a two or three-wire remote.
See pages 40-42.
If using a switched GFCI power
source, the heater post-purge function will be
bypassed, adversely affecting heater operation and
life.

ELECTRICAL WIRING
WARNING:
Heaters are factory-wired for
a 120
VAC, 60 Hz, single phase
power supply.
DO NOT
attempt to operate with any other power supply.
CAUTION:
Heater must be electrically grounded
and bonded. Bonding lug is provided loose with the
heater. Install bonding lug on lower right or left side
of jacket as necessary for bonding the heater.
Mounting hole is provided on the jacket.
The Electronic Intermittent Ignition Device automati-
cally lights the main burner upon a call for heat.
NOTE:
Failure to ground the heater electrically
could affect the heater’s electronics.
NOTE:
See page 42 for further instructions if using
a time clock/fireman’s switch.

NOTE:
If it is necessary to replace any of the origi-
nal wiring, use 105°C wire or its equivalent, and/or
150°C wire or its equivalent, like the original wiring.
