ixi gas pool and spa heater
Installation Manual
• Once a year check that water is running freely
through the pressure relief valve. To check, turn on
the filter pump and lift the release lever on the top
of the valve.
• Be sure combustion air and ventilation openings
are not blocked.
10.6.2 Guidelines For Professional Inspections
The following inspections should be made once a year
or as needed. Routine inspections are a critical to the
safety and long life of your AstralPool pool equipment.
• Check for loose or broken wires and terminal
connections.
• Check the water pressure switch by turning the
filter pump off and on several times. The burner
should go off immediately after the pump stops.
The fan run for 45 seconds after the burner shuts
down.
CAUTION
If the heater is wired serially to or on the same relay as
the fi lter pump, there is a chance that power will be
disconnected to the heater before the fan is able to
fully purge the combustion chamber. It is inadvisable to
install the heater in a manner which would prevent this
combustion chamber purge from taking place.
• An ignition sequence should start shortly after the
pump is turned back on.
• Inspection the thermal regulator valve (TRV).
• Inspect the electrical controls, specifically:
a. High limit switches.
b. Water pressure switch.
c. Automatic gas valve.
d. Power interface/Temperature control.
e. Flue temperature sensor.
f. Control circuit fuse.
g. Ignition control.
h. Air pressure switch.
• Inspect the inlet grill at the blower for blockage,
leakage, and corrosion.
• Inspect the combustion blower for damage.
• Conduct a normal operating cycle and observe
that the sequence proceeds as intended.
• If the heater is equipped with a pressure relief
valve, clean any accumulated corrosion and make
sure that water runs freely when lever is lifted.
• Inspect the outside of the combustion chamber
and blower for corrosion and indication of
improper operation.
• Inspect electrical controls for deterioration. Repair
and replace as necessary.
• Visually check the main burner flame. Remove the
top of the heater to inspect the sight glass. See
