Plumbing from the heater back to the pool or spa must
not have any valves or restriction that could prevent flow
when the pump is operating.

CAUTION:
An additional source of heated water, e.g. a
solar system, must be connected to the main line ahead
of the heater inlet pipe in order for it to act as the primary
heat source. If the primary system provides adequate heat
to maintain set-point, the heater will not fire. Be advised
that the control panel will then display sensed water
temperatures downstream of the primary heating system,
rather than the temperature of the water exiting the pool.
Heater must be located so that any water leaks will not
damage the structure of adjacent area.
6. 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 240 VAC
power supply. DO NOT attempt to operate at 208 VAC.
The standard field-wiring connection is on the right side
of the heater.
To wire the heater from the left side, follow these steps:
1. Remove the two (2) screws that hold the front door
to the heater. Remove and set aside door for better
access to wiring.
2. Remove the four (4) screws that hold down the
junction box to the sway brace.
3. Remove the transformer cover located on the far
right by removing one (1) screw.
4. Remove the two (2) screws that hold down the
transformer.
5. Remove the one (1) screw that holds down the
ground wires.
6. Disconnect P6 connector from PC board.
7. Remove transformer from its current location and
relocate it on the far left side of the heater.
8. Re-route all high-voltage wires and ground wires
through the left jacket side of heater.
9. Re-install P6 connector, ground wires (SPG),
transformer, junction box, front door, and plug right
side with the left side’s grommet plug.
NOTE:
7/8" diameter holes not utilized on jacket and
control box can be used for fireman switch, auxiliary
control interface or power vent (D-2) wiring.

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.
NOTE:
See "Time Clock/Fireman’s Switch" on page 29
for further instructions if using a time clock/fireman’s
switch.
The Electronic Intermittent Ignition Device automatically
lights the pilot and main burners upon a call for heat. The
heater is supplied with a dual-voltage transformer for 120
VAC or 240 VAC input power hookup.
