Gas-Fired Pool and Spa Heater | Installation & Operation Manual
9.5.1 Guidelines for Homeowner Inspections
WARNING
Do not store or use gasoline or other fl ammable vapors, liquids or
chemicals in the vicinity of this or any other appliance.
WARNING
Do not use this heater if any part has been under water. Immediately
call a qualifi ed service technician to inspect the heater and replace
any part of the control system and any gas control which has been
under water.
WARNING
To Reduce the Risk of Fire, install pool equipment in an area where
leaves or other debris will not collect on or around the equipment.
Keep surrounding area clear of all debris such as paper, leaves, pine-
needles and other combustible materials.
• Ensure the top of the heater, under the heater,
and surrounding area clear of all debris and
combustible materials such as paper, leaves, etc.
• If there is a pressure relief valve, check for
corrosion in and around the valve. If there
is corrosion, contact a pool professional for
replacement of the
pressure relief valve.
• Once a year check that water is running freely
through the pressure relief valve. To check, turn
on the fi lter pump and lift the release lever on the
top of the valve.
• Be sure combustion air and ventilation openings
are not blocked.
9.5.2 Guidelines for Professional Inspection
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 Jandy pool
equipment.
• Check for loose or broken wires and terminal
connections.
• Check the water pressure switch by turning the
fi lter pump off and on several times. The burner
should go off immediately after the pump stops.
The fan will 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.
• Inspect the thermal regulator valve (TRV).
• Inspect the electrical controls, specifi cally:
a High limit switches e Flue temperature
sensor
b Water pressure switch f Control circuit fuse
c Automatic gas valve g Ignition control
d Power interface/
Temperature 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 combustion chamber and blower exterior
for corrosion and indication of improper operation.
• Inspect electrical controls for deterioration. Repair
and replace as necessary.
• Visually check the main burner fl ame. Remove the
top of the heater to inspect the sight glass. See
