Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
All electrical work must be performed by a licensed electrician and conform to all national, state, and local
codes. When installing and using this electrical equipment, basic safety precautions should always be followed,
including the following:
WARNING
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal temperature of
the body reaches a level several degrees above the normal body temperature of 37°C. The symptoms of hyperthermia
include dizziness, fainting, drowsiness, lethargy, and an increase in the internal temperature of the body. The effects of
hyperthermia include: 1) unawareness of impending danger; 2) failure to perceive heat; 3) failure to recognize the need to
exit spa; 4) physical inability to exit spa; 5) fetal damage in pregnant women; 6) unconsciousness resulting in a danger of
drowning.
DANGER
To reduce the risk of severe injury or death, do not remove the suction fittings of your spa or hot tub. Never operate a spa
or hot tub if the suction fittings are broken or missing. Never replace a suction fitting with one rated less than the flow rate
marked on the equipment assembly.
WARNING
To Reduce the Risk of Injury -
a) The water in a spa should never exceed 40°C. Water temperatures should remain between 38°C and 40°C. The water in
a spa should never exceed 40°C. Water temperatures between 38°C and 40°C are considered safe for a healthy adult.
Lower water temperatures are recommended for young children and when spa use exceeds 10 minutes.
b) Since excessive water temperatures have a high potential for causing fetal damage during the early months of
pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 38°C. Before entering a spa
or hot tub, the user should measure the water temperature with an accurate thermometer since the tolerance of water
temperature-regulating devices varies.
d) The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with the
possibility of drowning.
e) Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory system problems,
or diabetes should consult a physician before using a spa.
f) Persons using medication should consult a physician before using a spa or hot tub since some medication may induce
drowsiness while other medication may affect heart rate, blood pressure, and circulation.
WARNING
Risk of electric shock - Install the controller at least 3.5 metres from the inside wall of the pool and/or hot tub using non-
metallic plumbing.
Children should not use spas or hot tubs without adult supervision.
Do not use spas or hot tubs unless all suction guards are installed to prevent body and hair entrapment.
People using medications and/or having an adverse medical history should consult a physician before using a spa or hot
tub.
WARNING
To avoid injury ensure that you use this control system to control only packaged pool/spa heaters which have built-in
operating and high limit controls to limit water temperature for pool/spa applications. This device should not be relied
upon as a safety limit control.

2.4 General Operation Description
The blower draws air and fuel through specially
designed orifices, delivering a precise mixture to
the burner, located inside the sealed combustion
chamber. Water flows through the heat exchanger,
which surrounds the burner transferring the heat to
the water. Exhaust gases are then directed through a
duct where it is vented to the atmosphere.

2.8 Heater Components
Header Type “A” Header Type “B”
abcf
gh
i
de
Front
Rear
Monitors temperature at the exhaust flue. If
excessive temperatures are detected,
combustion will stop and a fault will be displayed.
Flue Temperature Sensor
a
Indicates a safety control equipped to protect internal
components and extend the life of the heater.
Controls gas flow into the burner. Enables flow when the
temperature control calls for heat and all safety controls enable
operation. It also regulates gas pressure to -.05 kPa (-2” Water Column)
below the air pressure at the blower inlet. Necessary pressure regulation
cannot be accomplished with common (positive pressure) gas valves.
Gas Valve
g
When current is passed through the ceramic
material of the igniter it will achieve temperatures
great enough to initiate combustion of the air/fuel mixture.
Hot Surface Igniter
b
Provides energy for ignition, monitors flame quality
and controls the gas valve. Upon call for heat, the
blower is activated to purge the combustion chamber. Electrical power is
then applied to the hot surface igniter. When ignition temperature is
attained, the gas valve opens and ignition occurs. If stable flame is detected
the igniter will power down. If stable flame is not detected the control
system will close the valve to prevent further gas release. If a total of 3
ignition attempts fail an ignition fault is displayed.
Ignition Control
c
Rated at 43°C (109°F), 52°C (126°F) and
66°C (151°F) will prevent water of excessive
temperatures from being discharged from the heater. If the switch at the
header inlet, or if either switch at the heat exchanger outlet senses exces-
sive temperature, the gas valve will close and combustion will stop.
High Limit Switches
d
Senses water temperature by
means of a thermistor. Heater
will operate to attain and maintain the water temperature according to the
heater settings. Two separate thermostat settings are supported, typically
used to set pool and spa temperatures.
Pool/Spa Water Temperature Control
e
Senses whether or not water is available to
the heater by measuring back pressure at the
header inlet. If insufficient pressure is detected, the display will indicate a
“Check Flow” fault and combustion will stop.
Water Pressure Switch
f
Draws in air and fuel gas
creating an air/fuel mixture that
is passed through the burner for combustion. The fan will operate for
several seconds before flame initiation and after the flame is extinguished
to purge the combustion chamber for a clean burn and to expel any
residual exhaust gas.
Combustion Blower and Air Orifice
h
Monitors the vacuum (negative pressure) within
the blower housing. This switch verifies that air is
flowing through the combustion system by sensing pressure. If air flow is
inadequate, combustion will stop and a fault will be displayed.
Air Pressure Switch

Install the heater so that the top of the vent is at least 1.5 m (5')
from any building opening including windows, doors, air inlets
including pool spa blowers or any other opening into the
building with the exception of sub-floor ventilation.
The top surface of the heater must be at least 1.0 m (3') above any
forced air inlet, or intake ducts located within 3.0 m (10') horizontally.
Required exhaust
distance:
•500 mm (1.5')
from any return
wall, building
surface or
external corner.
•150 mm (6")

4.3 Indoor and Outdoor Shelter Installation
AstralPool does not encourage installation of ULPG
(Universal LPG) gas heaters indoors. Always consult
with the authority having jurisdiction (AHJ) along with
all applicable national and local codes before installing
a ULPG heater indoors. Please be sure to refer to
Section 5.3.
The heater is Certified by IAPMO-R&T Oceana for
indoor installations. Please keep in mind the
clearances from Section 4.1 when selecting an
installation location. You will also need to make
considerations for intake combustion air see Section
4.3.1 and exhaust venting see Section 4.3.3. In
addition, when pool equipment is installed indoors,
appropriate containment measures and drains should
be considered for the prevention of property damage
in the event of an equipment leak.
NOTE: An outdoor shelter is an unoccupied enclosure
which does not communicate directly with occupied
areas.
If the outdoor shelter is a completely closed structure, air
openings in accordance with the size recommendations
described in Section 4.3.1 must be maintained. If the
structure does not have outside air openings then air
must be provided for combustion by using our fresh air
vent kit.

4.3.1 Combustion Intake Air Supply
As outlined in the latest edition of ANSI standard
Z223.1 (NFPA 54), the heater location must be
properly vented to provide sufficient air supply for
proper combustion. Please also consult Australian
standards, AS/NZS 5263 and AS/NZS 5601.
When combustion air is supplied directly through an
outside wall, each opening should have a minimum
free area of 25.4 mm square (1 in2) per 1.2 kW input of
the total input rating of all appliances in the enclosed
area. If combustion air must pass through horizontal
ducts, each opening should have a minimum free area
of 25.4 mm square (1 in2) per 1.2 kW input of the total
input rating of all appliances in the enclosed area.
Details can be found in Figure 4.
The “Minimum Net Free Open Area” information
from Figure 4 is not applicable in installations where
exhaust fans or blowers of any type are used. Any
equipment which exhausts air from the room where
the heater is installed can deplete the combustion
air supply or reverse the natural draft action of the
venting system. This could cause flue products to
accumulate in the room. Additional air must be
supplied to compensate for such exhaust. Consult
a professional engineer to ensure that installations
where exhaust fans or blowers are used are designed
and installed in accordance with all applicable local
and national installation codes.
In addition, the heater must be completely isolated
and protected from any source of corrosive chemical
fumes or corrosive vapors (i.e chlorine or hydrochloric
acid).
WARNING
Do not store any chemicals, cleaners, or other corrosive
material near combustion air openings or in the
room. Avoid locating appliance vents in the vicinity of
combustion air openings. Failure to prevent corrosive
materials from mixing with combustion air can result in
reduced heater life and unsafe heater operation.

Table 2. Vent Pipe sizing Requirements
WARNING
Vent pipe materials, sizing, and installation must be
as required by the National Fuel Gas Code NFPA 54/
ANSI Z223.1 or Australia Standard for Gas Pool Heaters,
AS/NZS 5263, AS/NZS 5601 Gas Installations as
applicable by local code. Undersized pipe can result in
inadequate venting and oversize pipe can result in vent
condensation. Improper selection of vent pipe material,
incorrect sizing of the pipe, and incorrect installation of
vent piping can result in release of combustion products
to the indoors. This can cause serious injury or death by
Carbon Monoxide poisoning or asphyxiation.
WARNING
Improper installation or maintenance can cause nausea
or asphyxiation from carbon monoxide in ue gases
which could result in severe injury or death. For indoor
installations, as an added measure of safety, AstralPool
strongly recommends installation of suitable
carbon monoxide detectors in the vicinity of this
appliance and in any adjacent occupied spaces.
Incorrect design and installation of heater vents and
ducts can result in personal injury, damage to property,
or death. To avoid such hazards, the heater must
be installed only by a qualied professional service
technician.
• STATIC PRESSURE - NEGATIVE: Appliance
operates with a negative vent static pressure, a
vent gas temperature that avoids excessive
condensate production and will vent vertically
terminating at the roof. Termination must pass
through a properly installed and approved roof
jack, a properly sized storm collar and a listed vent
cap. See Figure 4.
• Do not terminate heater vents near air conditioning
or air supply fans which could pick up exhaust ue
products, such as carbon monoxide and other
hazardous euent, and return them inside the
building.
• Vent pipe type and material must be carefully
selected and depends on the type of installation.
• Do not locate the vent terminal where exhaust
ue products could strike against building
materials and cause degradation.
• Vent opening should be well away from
landscaping or other obstructions that would
prevent free air ow to and from vent terminal.
• Do not terminate vent under decks, stairs, or car
ports.
• Do not use the appliance to support the vent
pipe.
• Vent piping must be supported with no low spots
or sagging which could allow condensate to
collect.
• Install the vent pipe so it can expand and contract
freely with temperature changes.
• Do not run the heater vent into a common vent
with any other appliance.
• It is recommended that vent runs over 5.5 m
(18’) be insulated to reduce condensation. Use
a condensate trap in the vent run close to the
heater, especially in cold climate installations.

• Do Not install the heater in a sidewall terminated
conguration or run exhaust venting in a primarily
horizontal conguration. This heater is intended
for vertical vented applications only.
• Horizontal runs of vent piping may be used but
must not exceed 4.9 m (16 ft.) in length and must
always maintain the minimum pitch/slope for any
horizontal runs, as specied in Figure 4.

4.3.5 Precautions Against Common Venting
Seek the assistance of a Registered Professional
Engineer for proper design of a common venting
system.
AstralPool does not recommend using a common vent
to vent multiple appliances through a common duct.
However, if no other option is deemed available by the
installer, each appliance must have its own vent
temperature limit switch. All vent limit switches must
be wired in series so as to prevent any appliance from
firing in the event of a blocked vent. An outside draft
inducer must be installed to pull and create negative
pressure in the vent system. Refer to ANSI Z223.1 or
Australian standards applicable to Gas Pool Heaters,
AS/NZS 5263, AS/NZS 5601 for more information on
common venting multiple appliances. Do not connect
vent systems of different categories to the same
venting system.
4.3.6 Inspection and Replacement of Existing
Vent System With New Components
When replacing an existing pool heater with the IXI, it
is recommended that a new appropriate venting
system is installed with the new heater. However, if the
existing venting system must be used, be sure to
carefully inspect the existing system to ensure that it is
in good condition and appropriate for the IXI heater.
Replace any parts that are not in serviceable condition
before completing the installation.
Section 5. Gas Connections
Gas piping installation must be in accordance with the
latest edition of ANSI Z223.1 and the Australia
standard installations, AS/NZS 5601.1 along with all
local codes.
• Pressure Testing : The heater must be isolated
from the gas supply piping system by closing
the individual manual shut o valve during any
pressure testing of the gas supply piping system
at test pressure greater than or equal to 3.5 kPa (.5
psi).
CAUTION
Permanent damage to the gas valve will occur if the
installation procedures are not followed correctly.
WARNING
CONVERTING THIS HEATER FOR USE WITH ANY OTHER
FUEL TYPE IS NOT RECOMMENDED BUT, WHEN
NECESSARY, SHOULD ONLY BE PERFORMED BY A
LICENSED AND QUALIFIED PROFESSIONAL, AND ONLY
AFTER CONTACTING ASTRALPOOL FOR THE PROPER
INSTRUCTIONS AND CONVERSION KIT.
All questions should be directed to the AstralPool
customer service center at 1300 186 875.
5.1 Supply Gas Requirements
• Refer to AS/NZS 5601.1 for correct gas inlet piping
length from the gas meter to the heater.
• Conrm correct supply pipe size and supply
pressure before proceeding with the installation.
• Check the gas meter to make sure it will supply
enough gas to the heater and any other
appliances using the same gas supply. If unsure,
contact your local gas utility to conrm.
• It is critical that the incoming gas supply pressure
at the heater is within the maximum and
minimum pressure requirements as outlined in
Table 2. If the range of acceptable supply pressure
is not provided, the gas supply system to the
heater must be modied to meet pressure
requirements.
• Consider pipe ttings when determining gas pipe
sizing. For every elbow used add 900 mm (3’) to
straight pipe length.
• Install a manual gas shuto valve outside the
heater body for service and safety. Never install
the shuto valve inside the body of the heater.
• Where required by local code, install a sediment
trap/condensate fall and gas union in accordance
with Australia standard 5601. See Figure 5
• Do not use a restrictive gas cock.

• All readings must be made while heater is operating.
• Relying on any reading taken while heater is o may
result in poor performance and diculty in operation.
Table 3. Supply Gas Input Pressure
Requirements
• Verify the manual gas shuto valve is open.
• Make sure the heater is o.
• Remove the heater rear panel to expose the gas
valve.
NOTE: The rear panel is the main body panel closest to
the gas inlet. This may appear to be the front panel if the
user interface was moved to accommodate a left side
water connection. For instructions on moving the user
interface see 6.2.1.
ATTENTION
Do not use exible appliance connectors on any gas
connections unless the connector is AGA approved
for outdoor installation, and is marked with the BTUH
capacity (which must be equal to or greater than the
heater rated input) and the type of gas (Natural or
ULPG). Also, any exible connectors, such as CSST
buried underground must be certied for underground
installation and meet all applicable codes. Please note,
use of exible connector still requires the installation of a
sediment trap. See Figure 5.
NOTE: The gas line from the meter is usually larger
than the gas valve. Therefore, you will need to reduce
connecting pipe as necessary. Make this reduction as
close to the heater as possible.

• Turn the heater on.
• Inlet gas pressure must be taken while the heater,
and if possible, all other gas burning appliances
supplied by the same gas delivery system, are
operating.
• If the gas supply pressure is less than required.
Check for an undersized pipe between the meter
and the heater, a restrictive tting, or an
undersized gas meter. Make adjustments and
perform the test again. If needed contact the local
gas utility company for assistance.
• Once proper inlet pressure has been conrmed,
turn o heater.
• Remove manometer.
• Tighten the tap plug securely. DO NOT
OVERTIGHTEN.
WARNING
Failure to secure or replace the pressure tap plugs will
allow gas to leak from the valve into the heater body
which could result in property damage, severe injury, or
death.
• Before operating the heater, test the gas supply
system and all connections for leaks using a soap
solution. Do not use an open ame to test for
leaks.
5.3 Special Precautions for ULPG Gas
This appliance is approved for use with Universal LPG
(ULPG) and Natural Gas in Australia and New Zealand.
Under the same environmental conditions, ULPG is
denser or heavier than air and will more readily collect
or pool in enclosed areas if adequate ventilation is not
provided. It is not recommended to install ULPG gas
heaters in enclosed areas such as pits. Locate heaters a
safe distance from ULPG gas cylinders and filling
equipment. Consult the Australian / New Zealand
Standard AS/NZS 1596 and gas installation standard
AS/NZS 5601, and any other local codes and fire
protection authorities about specific installation
restrictions in your area.
For ALL installations the combustion air openings
requirements and AS/NZS 5601 MUST be followed
for safe and proper operation.

Section 6. Water Connections
Install pool system components with connections as
illustrated in Figure 6. Any configuration other than as
illustrated in Figure 6 can affect the operation of the
water pressure switch. Locating the heater above or
below the pool water surface can also affect operation
of the water pressure switch.
NOTE: When pool equipment is located below the pool
surface, AstralPool is not responsible for any large scale
water loss, ooding or damage caused by a leak.
CAUTION
The pool equipment must be protected from back-
siphoning of water. If there is any chance of back-
siphoning, provide a check valve between the pool and
the lter pump inlet.
6.1 Pump Sizing
The flow bypass within the heater manifold will
accommodate flows rates delivered to the heater from
a minimum of 114 Litres per minute (lpm) (30 gpm) to
a maximum flow of 379 lpm (100 gpm.)
CAUTION
The system water pump must be capable of providing
no less than 114 lpm (30 gpm) of ow through the
heater. Flow rates at less than 114 lpm (30 gpm) may
cause nuisance operation causing the heater to turn o
or damage to the heater.

6.1.1 Manual Bypass Valve
A manual bypass valve is to be installed in any system
in which the pump flow exceeds 378 lpm (100 gpm).
Connect ball valve between water inlet and outlet. See
inset “a.” in Figure 6.
• Adjust the valve to bring the ow rate within the
acceptable range. See Table 3.
• Remove the valve handle to avoid tampering.
6.1.2 Pump Sizing for New Pool Construction
When sizing a pump for the system, the head loss for
all system components must be added together when
determining the design flow rate. Component“Head
Loss at Flow” curves are available from equipment
manufacturers.
NOTE: In order to properly establish head loss at ow for
a lter, remember that a “dirty” lter can typically add 69
kPa (10 psi) of additional head loss, 7 extra metres (22 ‘)
of head. This must be considered when sizing a pump for
a new pool system.
6.1.3 Pump Sizing for Replacement in an
Existing Pool
If the IXI heater replaces a different model of heater,
determine if the existing pump is capable of providing
the minimum flow of 114 lpm (30 gpm). IXI heaters are
high efficiency heaters. Heaters typical of this
construction may have higher head loss characteristics
than the one being replaced.
CAUTION
Heater failure due to insucient water ow is not
covered under warranty. See measurements in the
Head Loss Chart. See Figure 7.
6.2 Plumbing Connections
The heater has a standard 50 mm (2”) water manifold
and coupling design. With this feature, only nominal
50 mm (2”) PVC or CPVC may be connected to the
heater. AstralPool recommends the use of 50mm (2”)
pipe with a minimum of 40mm (1.5”) to be fitted to the
heater.
6.2.1 Reverse Plumbing Connection
The IXI heater is shipped with the manifold on the
right side by default. If necessary the water
connections can be orientated to the left side by
rotating the top panel of the appliance.
NOTE: The electrical raceway, transformer, PIB, Ignition
control and voltage selector board are all accessed
through the default front panel. Special considerations
should be made for service clearance, see Figure 2,
before a nal location and orientation for the appliance
is determined.
• Turn o all power to the heater at the breaker.
• Ensure that the pump is o and will remain o for
the duration of the procedure.
a
Remove the four black screws securing the
heater top panel to the heater body.
b
Lift heater top panel. Be careful not to damage or
apply undue stress to the user interface wiring.
c
Rotate the heater top panel 180°.
• Place heater top panel securely on heater body.
• Secure with the four screws removed in step “a”.
• Restore power to the heater.
• Return heater to normal operation.
