| PAULIN HUMPHREY, GAS LIGHT TROUBLESHOOTING |
| PROBLEM |
POSSIBLE CAUSE |
POSSIBLE SOLUTION |
| Gaslight mantle has turned black. |
Bad mantles (too short inside would get too hot and burn out mantle). |
Replace mantle. |
| Bunsen has spider webs (most common reason for mantles turning black) |
Clean bunsen. |
| Need high altitude nozzle (above 4500 ft. - has smaller orifice). |
Install new high altitude nozzle. (L9-52A) |
| Using incorrect orifice for natural gas vs. propane. |
Install new natural gas nozzle. (L9-51A) |
| Gaslight mantle is broken. |
Touching mantle (pre-formed will crack and burn through even with flames). |
Replace mantle. |
| Breezes, bugs and vibrations will also break mantle. |
Replace mantle. |
| Gaslight pulsates or flickers - does not stay lit. |
If gaslight is new, nozzle (orifice) could be clogged. |
Blow air through to clean. Because the orifice is a very soft brass do not insert anything in hole. May need new orifice. |
| Check bunsen for spider webs, lint or fiber. |
Clean bunsen. |
| Check for lint or fiber in burner nose screen. Clean burner nose screen. |
May have to replace burner nose. |
| Gas line used should be no smaller than 3/8". If 1/4" must be used, run can be no longer than 8 ft. |
Check installation. |
| Regulator is bad: LP gas must be 11" on water column (6 oz. mercury) pressure. |
Check installation. Who installed? Was the testing equipment correct? Was regulator at tank checked? Check at wall connection also. |
| Wallplate may have been bent during installation, impairing gas flow. |
Loosen installation (but wallplate may have to be replaced). |
| OPK Kit - one light is brighter than the others. |
May be a mantle problem. |
Try another mantle - or try switching mantles. |
| Plugged nozzle (orifice) in wall plate. |
Blow air through to clean. Do not insert anything in hole (very soft brass). May need new orifice. |
| Flames shooting from mantle in gaslight. |
Low pressure regulator not being used. Gaslights are low pressure - the regulator in line should be 11" from column. Would most likely be lack of a regulator because low pressure is not enough to cause a flame. |
Have a low pressure regulator installed. Have the pressure checked by your installer. |
| Seal has been broken. Each time burner nose is removed from bunsen tube, a new seal is required. |
Put in new seal. |
| Cracks in burner nose. |
Need new burner nose. |
| Note: If you have more than one gaslight installed, switch malfunctioning gaslight parts with your good gaslight parts to determine whether the problem is with a gaslight part or pressure. |
