TROUBLESHOOTING

SYMPTOM

POSSIBLE CAUSE

 

 

4. Leaking tank.

5.Pilot burner flames adjusted properly, but fluctuate to very low and blow out easily.

A.Foam-over by depleted shortening permits oil to drip from the tank surface, giving the appearance of leaking.

B.Careless draining procedures. Gas valve should be in the PILOT or OFF position before draining oil. Burners heating an empty tank will damage tank joints.

C.Carbon buildup causes rapid attack on tank by promoting acid formulation.

A.Check gas pressure at submanifold fitting on fryer when fryer is in operation. Check all other equipment on the same gas line in operation.

B.Pressure at submanifold (pipe on which burners are mounted) should not be less than 4.0" W.C. (natural and mixed gas) or 10" W.C. for propane gas.
