SYMPTOM
Leaking tank.
Pilot burner flames
adjusted properly, but
fluctuates to very low and
blows out easily.
CAUSE
Foam-over by depleted
shortening permits oil to
drip from the tank surface,
giving appearance of
leaking.
Careless draining
procedures.
Carbon buildup causes
rapid attack on tank by
promoting acid formulation.
Gas pressure too low.
Gas pressure too low at
submanifold.

EF SERIES GAS FRYERS
REMEDY
Replace shortening.
Gas control valve knob should be in
PILOT or OFF position before
draining oil. Burners heating an empty
tank will damage tank joints.
Clean tank surfaces.
Check gas pressure on submanifold
fitting when fryer is in operation.
Check other equipment attached to
same gas line.
Adjust gas pressure at submanifold to
not less than 4.0" W.C. (natural and
mixed gas) or 10.0" W.C. for propane
gas.
