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.
