Check movement by putting in hot water (110°F or higher). If no movement, replace. Locate the restriction and remove. Flush system and clean. Remove debris or blow out gas line. Scale forming in heat exchanger - clean heat exchanger and check pool pH and total alkalinity. Heater going on and off continuously Dirty filter.............................................. Low water level in pool........................ External bypass setting out of adjustment............................................ *Pressure switch out of adjustment..... Clean or replace filter. Raise water level. Adjust bypass. Adjust pressure switch. Liming or scale forming in exchanger Pool water............................................ Bypassing too much water................... U.G. not functioning............................. See Water Chemistry on page 2. Inspect bypass for movement, if no movement, replace. Replace if no movement when heated. Sooting High flow rates..................................... U.G. Inoperative................................... *Air starvation....................................... *Improper venting................................ *Insects or debris clogging burner intake ports............................. Reduce by adding manual bypass valve. Adjust manual bypass valve until heater outlet water temperature is between 105°F and 110°F. Check movement by putting in hot water (110°F or higher). If no movement, replace. Refer to installation instructions. Follow recommended installation instructions. Clean burners. Pilot outage Low gas pressure................................ Restricted pilot..................................... Weak pilot generator............................ Adjust gas pressure. Clean pilot. Replace pilot. Yellow lazy flame Low gas pressure................................ *Insects or debris clogging burner intake ports............................... Adjust gas pressure. Clean burners. Outer jacket very hot (paint blistered) *Broken refractory caused by shipping damage or improper combustion......................................... Excessive sooting of heat exchanger.. Replace refractory panels. Determine cause of sooting & correct. Takes too long to heat pool or spa Under-sized heater............................... Filter not running long enough............. Dirty filter.............................................. Gas line or meter undersized............... Calculate heating capacity of heater: Htr. output(BTUH) Pool gallonage x 8.33 or refer to heater sizing chart. This does not take into account heat loss due to weather. Reset time clock. Clean filter. Refer to installation instructions. Leaking at well Overacid............................................... Replace well and maintain proper water chemistry. Leaking at heat exchanger Overacid............................................... Replace heat exchanger and maintain proper water chemistry. Gasket brittle and leaking ( overheated) Heater running after pump shuts off.... Refractory damage.............................. Sooted heater....................................... See Pressure Switch Adjustment. Replace refractory. Determine cause of sooting and correct. Combustion fan not running Fan relay.............................................. Fan........................................................ Burned motor ...................................... Air pressure switch............................... Replace fan relay. Loose connection or failed motor. Incorrect wiring, replace blower. Replace air switch. * Indicates symptom which usually occurs on initial start-up. 43 ELECTRICAL - STANDING PILOT MILLIVOLT POOL OR SPA HEATER ELECTRICAL CHECK WITH MILLIVOLT GAS VALVE CAUTION: For qualified service personnel only. 1. Filter must be on with adequate water flow through heater. 2. Gas valve must be in "ON" position. Thermostat set higher than pool water temperature. 3. Jumpers are for temporary check only. If left in place, they could cause the heater to burn up. If pilot burner remains lit Jump across pressure switch terminals If main burner does not fire, remove jumper Check for adequate water flow from filter Replace pressure switch Jump across thermostat If main burner fires, remove jumper If main burner does NOT fire... Jump across each high limit and remove jumperReplace thermostat Replace high limit that caused heater to fire Jump across both "TH" wires on gas valves Check gas supply, gas line size, gas pressure. Also check for insects or debris in pilot output If pilot burner does not light Light pilot If pilot burner goes out when main burner lights or when gas valve knob is released If burner does not remain lit, attach millivolt meter and read pilot output If below 500mV, check gas pressure. Also check for insects or debris in the pilot burner If main burner fires, remove jumper Replace gas valve If main burner does not fire, remove jumper Remove both "TH" wires from gas valve. Relight pilot If pilot burner stays on Problem ...
