| 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 | |||

Liming or scale forming on | Pool water | Recommended pH should be between 7.4 and 7.8 | ||||
heat exchanger |
|
|
| Total alkalinity | ||
|
|
|
| Hardness | ||
Sooting | High | flow | rates | Reduce by adding manual bypass valve. Adjust | ||
|
|
|
| manual bypass valve until heater outlet water | ||
|
|
|
| temperature is 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. |
| |||
|
|
|
|
| ||
Pilot outage | Low | gas | pressure | Adjust gas pressure. | ||
| Restricted | pilot | Clean pilot. |
| ||
| Weak pilot generator | Replace pilot. |
| |||
|
|
|
|
| ||
Yellow lazy flame | Low | gas | pressure | Adjust gas pressure. | ||
| *Insects or debris clogging |
|
|
| ||
| burner intake ports | Clean burners. |
| |||
|
|
|
|
| ||
Outer jacket very hot | *Broken refractory caused by |
|
|
| ||
(paint blistered) | shipping damage or improper |
|
|
| ||
| combustion | Replace refractory panels. | ||||
| Excessive sooting of heat |
|
|
| ||
| exchanger | Determine cause of sooting & correct. | ||||

|
| or refer to heater sizing chart. 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. | ||||
|
|
| ||||
Liming | Bypassing too much water | Inspect bypass for movement, if no movement, | ||||
|
|
|
| replace. |
| |
| U.G. not functioning | Replace if no movement when heated. | ||||
|
|
|
| |||
Leaking at well. | Overacid | Replace well and maintain water chemistry properly. | ||||
|
|
|
| |||
Leaking at heat exchanger. | Overacid | Replace heat exchanger and maintain chemistry | ||||
|
|
|
| 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. | ||||
