INSTALLATION GFS SERIES TUBE FRYERS Step 3: Install the Legs (or Casters) and Restraints A set of legs or casters is packed with the fryer. A threaded pad is fastened to the base frame at each corner (see illustration on page 7). Each leg or caster has a similar mating thread. When casters have been ordered, the casters are provided with a Zerk fitting for proper lubrication when required. INSTALLATION 1. Raise fryer sufficiently to allow legs or casters to be screwed into the pads.
INSTALLATION GFS SERIES TUBE FRYERS Step 4: Check Clearances and Ventilation Select a firm, level location for your Southbend fryer. Leave clearance, whenever possible, so that access from the rear is possible to permit cleaning. If the unit is to be set on non-combustible flooring, such as a concrete slab, 3 inches minimum toe room must be provided to prevent restriction of the air opening in the bottom of the unit. There must be adequate clearance between fryer(s) and construction.
INSTALLATION GFS SERIES TUBE FRYERS Step 5: Gas Connection A 3/4" male NPT line for the gas connection is located near the lower left rear corner of the fryer (see illustration on page 7). The serial plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to burn (natural gas or propane). The fryer should be connected ONLY to the type of gas for which it is equipped. INSTALLATION A millivoltage circuit diagram is located inside the front door of the fryer.

OPERATION GFS SERIES TUBE FRYERS O PERATION NOTICE OPERATION These procedures must be followed by qualified personnel or warranty will be voided. All Southbend GFS Series Tube Fryers are immersion tube fryers. This is the most efficient method of transmitting heat into the oil. The tubes are actually large heat exchangers. Each tube is heated by a burner at its front that propels its flame and heat into the tube, toward the rear, where it is vented into a flue box.
OPERATION GFS SERIES TUBE FRYERS 3. While pressing the knob down, use a lit match to ignite the pilot. Continue to press the knob down for about 30 seconds. If the pilot does not stay ignited when the knob is released, repeat the lighting procedure and keep the knob down longer. Adjustment of pilot flame may be necessary. 4. When the pilot stays ignited, turn the knob counterclockwise to the “ON” position. Do not press down on the knob in this step. 5.
OPERATION GFS SERIES TUBE FRYERS Automatic Pilot Valve The Automatic Pilot Valve provides an automatic safety shutoff for the fryer when the pilot flame is extinguished. When the pilot flame is burning, the valve is held open electromagnetically by the electrical current from a thermopile in the pilot flame. When the pilot flame goes out, generation of current ceases and the valve closes automatically.
GFS SERIES TUBE FRYERS COOKING HINTS C OOKING H INTS User Tips • Smoking oil means that the temperature is too high, or that the oil has broken down. • Gum in frypot denotes a need for thorough cleaning (see “Weekly Cleaning” on page 18) • Use different oil for oily foods (mackerel, nutmeg, etc.) than for foods with water-soluble flavors (potatoes, onions, etc.). • Taste oil for quality. Replace it regularly. • Poor oil cannot produce good food.
COOKING HINTS GFS SERIES TUBE FRYERS Frying Don’ts • Don’t turn on the fryer with no shortening in the frypot. • Don’t fill the frypot above the line on rear of frypot. • Don’t allow oil in frypot to fry down to the point where there is insufficient oil in which to fry a full load. • Don’t have heat on tubes when they are not entirely covered with frying oil. • Don’t allow oil in frypot to be heated above 375°F and never turn thermostats to 400°F or over, even when bringing up the temperature.
CLEANING GFS SERIES TUBE FRYERS C LEANING Southbend equipment is constructed with the best quality materials and is designed to provide durable service when properly maintained. To expect the best performance, your equipment must be maintained in good condition and cleaned daily. Naturally, the frequency and extent of cleaning depends on the amount and degree of usage. Following daily and more extensive periodic maintenance procedures will increase the life of your equipment. Climatic conditions (e.g.
CLEANING GFS SERIES TUBE FRYERS CLEANING 5. Close drain valve and strain the oil back into the frypot through several thicknesses of cheesecloth, or filter it back using a filter machine.
GFS SERIES TUBE FRYERS CLEANING Darkened areas, called “heat tint,” sometimes appear on stainless steel surfaces where the area has been subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the stainless steel and are not harmful.
SERVICE GFS SERIES TUBE FRYERS S ERVICE NOTICE Warranty will be void and the manufacturer is relieved of all liability if: (A) Service work is performed by other than a qualified technician, OR (B) Other than genuine Southbend replacement parts are installed. ! WARNING Adjustments and service work may be performed only by a qualified technician who is experienced in, and knowledgeable with, the operation of commercial gas cooking equipment.
GFS SERIES TUBE FRYERS SERVICE Checking and Adjusting Pressure Regulator The combination gas valve and pressure regulator is factory set at 4" W.C. for natural gas and 10" W.C. for propane gas. To check the manifold pressure, do the following: 1. Turn thermostat “OFF” (lowest position) and combination gas valve knob to the “PILOT” setting. 2. Remove pressure tap plug from burner manifold located directly below the burners in the cabinet. 3. Install a fitting appropriate to connect a manometer. 4.
SERVICE GFS SERIES TUBE FRYERS Checking and Adjusting Auto Safety Pilot The pilot flame should surround the thermopile for 1/2". It must be large and sharp enough to cause the thermopile to glow a dull red, or sufficient to hold the safety valve open. 1. Remove pilot adjustment cap (see wiring diagram on page 24 for location). 2. Adjust pilot key to provide properly sized flame. 3. Replace pilot adjustment cap.
SERVICE GFS SERIES TUBE FRYERS Troubleshooting Problem Likely Cause Burners do not come on Gas supply to unit off. Combination gas valve is in “OFF” or “PILOT” position. Pilot not ignited. Thermostat not “ON.” Pilot will not stay ignited Combination gas valve is in “OFF” position. Pilot gas not adjusted properly. Gas supply to unit off. Bad thermopile. Dirty thermopile connections at combination gas valve or high limit. Bad magnet assembly in combination gas valve. Clogged orifice. Draft condition.
