MECHANICAL (FOR QUALIFIED SERVICE PERSONNEL ONLY)
PROBLEM | CAUSE | SOLUTION |
Harmonics, or whining noise. | U.G. inoperative | Check movement by putting in hot water (110°F |
|
| or higher). If no movement, replace. |
| *Debris or restriction in system | Locate the restriction and remove. Flush system |
|
| and clean. |
| *Debris in gas line | Remove debris or blow out gas line. |
| Low flow | Scale forming in heat exchanger - clean heat |
|
| exchanger and check pool pH and total alkalinity. |
Heater going on and off continously.
Liming or scale forming on
7.8heat exchanger.
Sooting
Pilot outage.
Yellow lazy flame
Outer jacket very hot (paint blistered)
Takes long time to heat pool or spa.
Dirty filter | Backwash filter. | |||
Low water level in pool | Raise water level. | |||
External bypass setting out of |

adjustment | Adjust pressure switch | |||
Pool water | Recommended pH should be between 7.4 and | |||
| 7/8 total alkalinity | |||
| ness | |||
High flow rates | Reduce by adding manual bypass valve and | |||
| adjust by putting thermometer in header (1/4" | |||
| NPT) drain opening. Set bypass so thermometer | |||
| reads between 105° and 110°F. | |||
U.G. Inoperative | Check movement by putting in hot water (110°F | |||
| or higher). If no movement, replace. | |||
*Air starvation | Refer to installation instructions. | |||
*Improper venting | Follow recommended installation instructions. | |||
*Insects or debris clogging |

|
|
burner intake ports | Clean burners. | |||
Low gas pressure | Adjust gas pressure. | |||
Restricted pilot | Clean pilot. | |||
Weak pilot generator | Replace pilot. | |||
Low gas pressure | Adjust gas pressure. | |||
*Insects or debris clogging |
|
|
|
|
burner intake ports | Clean burners. | |||
*Broken refractory caused by |

|
|
|
shipping damage or improper |
|
|
|
|
combustion | Replace refractory panels. | |||
Excessive sooting of heat |
|
|
|
|
exchanger | Determine cause of sooting & correct. | |||
Calculate temperature in °/hr | Heat rise (°/hr.)= Heater Output | |||

| |
| This does not take into account heat loss due | |||
| to weather. | |||
Filter not running long enough | Reset time clock. | |||
Dirty filter | Clean filter. | |||
Gas line or meter undersized | Refer to installation instructions. |
