WARNING If these instructions are not followed exactly, a fire or explosion may result,
causing property damage, personal injury, or death.
FOR YOUR SAFETY: This product must be installed and serviced by a contractor who is licensed and qualified in pool equipment by the jurisdiction in which the
product will be installed where such state or local requirements exists. In the event no such state or local requirement exists, the installer or maintainer must
be a professional with sufficient experience in pool equipment installation and maintenance so that all of the instructions in the manual can be followed exactly.
Before installing this product, read and follow all warning notices and instructions that accompany this product. Failure to follow warning notices and instructions
may result in property damage, personal injury, or death. Improper installation and/or operation can create carbon monoxide gas and flue gases which can cause
serious injury, property damage, or death. For indoor installations, as an additional measure of safety, Zodiac Pool Systems, Inc. strongly recommends installation
of suitable carbon monoxide detectors in the vicinity of this appliance and in any adjacent occupied spaces. Improper installation and/or operation will void the
warranty.
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
WHAT TO DO IF YOU SMELL GAS
• Immediately switch off main gas supply.
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
Installation and service must be performed by a qualified installer, service agency or the gas supplier.
Information in this Quick Reference Guide is not intended to replace the instructions found in the complete Heater Installation and Owner’s manual.
Read the manual in its entirety before attempting any of the procedures found in this Quick Reference Guide.

WATER CHEMISTRY
• Proper chemical balances are necessary
for sanitary bathing conditions, as well
as ensuring your heater’s long life.
• For spas, it is necessary to perform
water changes, in addition to chemical
treatment. Change the spa water every
60 days for light usage and every 30
days if usage is heavy.
• Zodiac Pool Systems, Inc. does not
warrant heat exchangers damaged by
corrosive chemical levels or excess
dissolved solids in pool or spa water.
Refer to the recommended chemical
levels, see table right. CORROSIVE WATER

INDOOR INSTALLATIONS
Combustion Air Supply
• All indoor installations must have
openings to outside air for combustion
and ventilation from the inside of the
building.
• As outlined in ANSI®standard Z223.1
(NFPA®54), the room in which the
heater is installed should have two
permanent air supply openings: (1)
within 12 inches (305 mm) of the
ceiling, and (2) within 12 inches (305
mm) of
the floor.
• All air from outdoors should have a net
free area, as shown in the table (right).
If using screens or metal louvers, add
additional area. Consult the specific
louver manufacturer for restriction
specifications as different louvers will
have varying restrictions.
* Area indicated is for one of two openings:
(1) 12ʺ from floor level, and (2) 12ʺ from ceiling level.

• Check supply pressure and local code
requirements before proceeding with
installation.
• Consider pipe fittings when
determining gas pipe sizing.
• Larger pipe size can be used if
required by local code.
• It is critical that the incoming gas
supply pressure at the heater is
within the maximum and minimum
pressure requirements. If the range
of acceptable supply pressure is not
provided, the gas supply system to
the heater must be modified to meet
pressure requirements.
• The gas shut off valve must be
installed in an accessible location
within six (6) feet of the heater.
• Do not use CSST or any flexible
gas piping.
GAS LINE SIZING
* Numbers are for natural gas (0.65 Sp. Gr.) based on 1/2 inch (3.45 kPa) water column pressure drop. Check
supply pressure with a manometer, and local code requirements for variations. For LP gas, reduce pipe
diameter by one size, but maintain a minimum 3/4 inch diameter.
For specific requirements:
(1) Natural gas heaters, refer to NFPA®54.
(2) Propane heaters, refer to NFPA 58.

For detailed information, refer to the complete installation and owner’s manual.

GAS PRESSURE TEST
• Check the gas supply pressure while
the heater is operating.
• Any adjustments or readings made
while the heater is off will result in poor
performance and other problems.
• Connect a differential manometer
to the supply pressure port on the
gas valve.
• If the gas supply pressure does
not meet requirements (see table,
right), check for a restrictive fitting,
undersized gas meter, or undersized
pipe between the meter and the heater.
• Minimum inlet supply pressure must
be maintained during heater operation
while there is a full demand on the gas
delivery system.

PRV SET-UP
• A pressure relief valve
(PRV) is recommended in all
installations.
• A PRV is required in any
installation in which the water
flow can be shut off between
the heater outlet and the pool/
spa. Check any applicable
installation codes in your
area to determine whether a
pressure relief valve is required.
• A pressure relief valve is not
supplied with the heater.
• Maximum working pressure of
this heater is 50 psi.
• Any PRV installed must comply
with provisions of the standard
described in ANSI®Z21.22 for
the United Sates or CSA 4.4 in
Canada.

GAS LINE SEDIMENT TRAP
• Do not use flexible gas
piping, it will restrict the
gas flow to the heater.
• Do not use a restrictive
gas cock.
• Install a sediment trap
and union ahead of the
gas controls and outside
the heater panels.
• Sediment trap should be
installed as close to the
inlet as possible.

For detailed information, refer to the complete installation and owner’s manual.

POWER CONNECTIONS
• The heater comes factory-wired intended for use
with 240 Volt, 60 Hz AC field electrical supply.
• Do NOT use with 208 Volt.
• To use 120 Volt, 60 Hz AC, change the position
of the voltage selector board on the power
distribution board (see procedure below right).
• Electrical wiring must be done in accordance
with the latest edition of the National Electrical
Code®(NEC®) NFPA®70. In Canada, the Canadian
Electrical Code (CEC), CSA C22.1, must be
followed.
• Take care not to abrade or damage any wiring or
other components.
The voltage selector board is keyed so that it will
fit in only one (1) direction for the selected voltage
(either side of the board).
1. Cut the plastic wire tie fastening the voltage selector board in place
2. Unplug the voltage selector board from the receptacle.
3. Rotate the voltage selector board 180 degrees and reinsert it into the
receptacle so that the hole in the board is not visible.
4. Verify that the board is securely seated in the receptacle.

WIRE TO 120V OR
240V/60 HZ
1. Remove the front panel of
the heater.
2. Connect the wires from the
power source to the leads
on the heater.
• Electrical wiring must be done in accordance with the
latest edition of the National Electrical Code®(NEC®)
NFPA®70. In Canada, the Canadian Electrical Code
(CEC), CSA C22.1, must be followed.
• Take care not to abrade or damage any wiring or other
components.
• The “hot” wire of the 120V power supply has to be
connected to the black wire (ACH1) on the power
distribution board and the “neutral” wire of the 120V
power supply has to be connected to the red wire
(ACN1).
WARNING
