Electrical Wiring

NOTE: If it is necessary to replace any of the original
wiring, use 105°C wire or its equivalent, and/or 150°C
wire or its equivalent, like the original wiring.
WARNING: Heaters are factory-wired for a 120 VAC,
A
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.
NOTE: Failure to ground the heater electrically could
affect the heater's electronics.
The Electronic Intermittent Ignition Device automatically
lights the main burner upon a call for heat.
NOTE: See page 35 for further instructions if using a
time clock/fireman's switch.

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.

Figure 21. 120 VAC Wiring
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.)
A WARNING: The transformer's primary side is wired
for 120 VAC and if 240 VAC is applied, damage to the
transformer and PC board may result. Such damages are
not covered under manufacturer'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 34 and 35. If using a switched
GFCI power source, the heater post-purge function will
be bypassed, adversely affecting heater operation and
life.
