Pool & Spa Heaters

PROBLEM CAUSE SOLUTIONPilot outage. Low gas pressure..................... Adjust gas pressure.Restricted pilot.........................Clean pilot.Weak pilot generator.................. Replace pilot.Faulty Detection Electrodeor PCBYellow lazy flameLow gas pressure...................... Adjust gas pressure.*Insects or debris cloggingburner intake ports.....................Clean burners.Inner & Outer panels very hot(paint blistered - thermal fusein transformer failed)*Gaps in corner of refractoryBroken refractory caused byshipping damage or impropercombustion...............................Replace or re-align refractory to sealgaps. Replace transformer.Excessive sooting of heatexchanger................................Determine cause of sooting & correct.Takes long time to heat Calculate temperature in °/hr......Heat rise (°/hr.)= Heater Outputpool or spa. Pool gallonage x 8.33or refer to heater sizing chart.This does not take into account heatloss due to weather.Filter not running long enough.....Reset time clock.Dirty filter.................................Clean filter.Gas line or meter undersized......Refer to installation instructions.LimingBypassing too much water..........Inspect bypass for movement, if nomovement, replace.U.G. not functioning.................Replace if no movement when heated.Leaking at well. Overacid.................................. Replace well and maintain waterchemistry properly.Leaking at heat exchanger. Overacid.................................. Replace heat exchanger and maintainchemistry properly.Gasket brittle and leaking - Heater running after pump(overheated). shuts off................................... See pressure switch adjustment.Refractory damage.................... Replace refractory.Sooted heater........................... Determine cause of sooting and correct.(* Usually occurs on initial start-up.)3108-08-01
