These procedures must be followed by qualified personnel or warranty will be voided.
All Southbend GFS Series Tube Fryers are immers ion tube fryers. This is the most efficient method of
transmitting heat into the oil. The tubes are actually lar ge heat ex changers . Each tub e is heated by a bur ner
at its front that propels its flame and heat into the tube, toward the rear, where it is vented into a flue box.
The combined heat transfer area of the tubes is much great er than the other types us ing element coils or
under-fired pots. Consequently, heat transfer per square inch is lower, as is th e temperatur e, but bec ause of
the increased surface area, immersion tube fryers transf er more heat into t he oil. The lower temperatur e of
the heating surface prevents scorching and carbonizatio n of the oil. Higher heat trans fer rate gives faster
recovery between loads.
Another advantage of immersion tube fryers is the col d zone. As oil is heated it passes between and over the
tubes and rises into the frying zone, where it imparts heat into the pr oduct. Af ter giving up heat, it descends
to the cooler zone below the tubes. Food particles and c rum bs are dropped and tr apped in the cold zone as
the oil awaits to be recirculated. The cold zone concept helps keep the oil circulating and clean of debris.
! WARNING
BURN HAZARD
Contact with hot oil will cause severe burns. Always use caution. Oil at 2 00°F is m ore dangerous than
boiling water.
! CAUTION
NEVER OPERATE THE FRYER WITHOUT SUFFICIENT OIL TO COVER THE TUBES.
Lighting
! CAUTION
IF YOU SMELL GAS DURING THE LIGHTING PROCEDURE, IMMEDIATELY SHUT OFF THE GAS
SUPPLY UNTIL THE LEAK HAS BEEN CORRECTED.
Open the burner compartment door and do the following:
1. Turn thermostat to “OFF” (lowest position) .
2. Press down the knob of the com bination gas
