Installation and Service Manual
WARNING: Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the pool heater.
High Water Temperature Limit Control
This pool heater is equipped with a fixed setting, auto reset high water temperature limit control that is screwed into the outlet head in the heat exchanger. This temperature limit control has a maximum limit setting of 200°F (93°C). It is also equipped with an adjustable setting, manual reset high water temperature limit control. This temperature limit control has a maximum limit setting of 230°F (110°C). If water temperature exceeds the set point, the limits will break the control circuit and shut down the pool heater. The auto reset limit control will only be reset after the water temperature has cooled below the set point of the limit. The manual reset limit control will require an operator to push the reset button (located immediately below the high limit dial) if this limit has tripped.

Figure 51 - Flame Pattern Illustration
Normal Flame: A normal flame is blue with slight yellow tips, has a
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.
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
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.
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.
