Troubleshooting
Water Heater Pilot Lights
PILOT OUTAGE |
|
| CONDITION | SOLUTION |
| Gas pressure incorrect | Set inlet pressure at a minimum 11" W.C. with two or more appliances running |
| Blocked “U” tube | Remove obstruction |
| Improper main burner alignment | Re-align main burner and main burner orifice holder and gas valve |
| Improper air adjustment | Adjust main burner air shutter approximately 1/4 open |
| Weak thermocouple | Replace thermocouple |
| Poor pilot flame | Clean or replace pilot orifice |
| Weak gas control magnet | Replace gas control |
| Defective E.C.O. in control | Replace gas control and check the pilot flame. It should be high enough to engulf the thermocouple at all times |
PILOT OUTAGE WHEN BUTTON OR KNOB IS RELEASED |
|
| CONDITION | SOLUTION |
| Thermocouple not hot | Hold button or knob for 30 seconds before releasing |
| Thermocouple loose | Tighten connection at gas control |
| Weak thermocouple | Replace thermocouple |
| Weak gas control magnet | Replace gas control |
| Defective E.C.O. in control | Replace gas control |
MAIN BURNER WILL NOT IGNITE |
|
| CONDITION | SOLUTION |
| Blocked main burner orifice | Clean or replace orifice |
| Main burner flame spreader mis-alignment | Square flame spreader to end of main burner |
| Blocked main burner | Remove blockage |
| Improper air adjustment | Adjust main burner air shutter approximately 1/4 open |
| Blocked “U” tube | Remove blockage |
| Gas control out of calibration | Replace gas control |
ERRATIC MAIN BURNER FLAME |
|
| CONDITION | SOLUTION |
| Improper gas pressure | Set inlet pressure to a minimum of 11½ W.C. with two or more appliances running |
| Improper air adjustment | Adjust main burner air shutter approximately 1/4 open |
| Partial blockage of main burner | Remove blockage |
| Partial blockage of main burner orifice | Clean or replace orifice |
| Flame spreader misaligned | Re-align spreader or replace main burner |
| Blockage in “U” tube | Remove blockage |
| Poor gas supply | Replace gas supply |
| Exhaust grille blocked | Remove blockage |
| Improper main burner alignment | Re-align main burner, main burner orifice holder and gas valve |
SMOKING AND SOOTING |
|
| CONDITION | SOLUTION |
| Gas pressure incorrect | Set inlet pressure to a minimum of 11½ W.C. with two or more appliances running |
| Poor gas supply | Replace gas supply |
| Improper pilot flame | Clean or replace pilot orifice |
