Installation and Service Manual
CLEANING AND
MAINTENANCE
Listed below are items that must be checked to ensure safe reliable
operations. Verify proper operation after servicing.
ƽ CAUTION: Label all wires prior to
disconnection when servicing controls. Wiring
errors can cause improper and dangerous
operation.
Appliance Area
Keep appliance area clear and free from combustible materials,
gasoline and other flammable vapors and liquids.
Water Circulating Pump
Inspect the pump every six months and oil as necessary. Use SAE
30 non-detergent oil or lubricant specified by the pump
manufacturer.
Burner Flames
Visually check the main burner flames at each start up after long
shutdown periods or at least every six months. Burner view ports
are located on the right and left sides of the pool heater.
ƽ WARNING: The areas around the burner view
ports are hot. Direct contact with the pool heater
could result in burns.
Figure 51 - Flame Pattern Illustration
Normal Flame: A normal flame is blue with slight yellow tips, has
a well-defined inner cone, and displays no lifting flames.
Yellow Tips: The usual causes for yellow tips on the burner flame
are burner air flow blockage or partial obstruction.
Yellow Flames: The usual causes for yellow flames are primary air
flow blockage to the burner(s) or excessive gas input. Correct this
condition immediately.
Lifting Flames: The usual causes for lifting flames are over firing
the burner(s), excessive primary air, or high draft.
If you observe improper flame patterns, examine the venting
system, ensure proper gas supply, and ensure adequate supply of
combustion and ventilation air.
Flue Gas Passageways Cleaning Procedures
Any sign of soot around the refractory, at the burners or in the areas
between the fins on the copper heat exchanger indicates a need for
cleaning. The following cleaning procedures must only be
performed by a qualified serviceman or installer. Proper service is
required to maintain safe operation. Properly installed and adjusted
pool heaters seldom need flue cleaning.
IMPORTANT: All gaskets on disassembled
components must be replaced with new gaskets on
reassembly. Gasket kits are available from your
distributor.
