LG SERIES GAS FRYERS INTRODUCTION GENERAL Vulcan Fryers are produced with quality workmanship and material. Proper installation, usage and maintenance will result in years of satisfactory performance. Before installing the fryer, thoroughly read this manual and carefully follow all instruction. This manual is applicable to model listed on the cover page. Procedures in this manual will apply to all models unless specified.
LG SERIES GAS FRYERS INSTALLATION Before installing the fryer, verify that the type of gas (natural or propane) agrees with the specifications on the fryer data plate, which is located on the inside of the door panel. Make sure the fryer is configured for the proper elevation. Record your fryer model, device, and serial numbers for future reference in the space provided below. This information can be found on the fryer data plate.
LG SERIES GAS FRYERS CODES AND STANDARDS The fryer must be installed in accordance with: In the United States: State and local codes, or in the absence of local codes, with: National Fuel Gas Code, ANSI-Z223.1/NFPA #54 (latest edition). Copies may be obtained from The American Gas Association Accredited Standards Committee Z223, @ 400 N. Capital St. NW, Washington, DC 20001 or the Secretary Standards Council, NFPA, 1 Batterymarch Park Quincy, MA 021697471.
LG SERIES GAS FRYERS Locate the fryer under a hood with adequate connection to an exhaust duct. The hood must extend 6” (15 cm) beyond fryer on both sides. Clearance above the fryer should be adequate for combustion byproducts to be removed efficiently. An 18” (46 cm) minimum clearance should be maintained between the flue vent and the filters of the hood venting system. Never make flue connections directly to the fryer. Do not obstruct the flow of the gases from the appliance.
LG SERIES GAS FRYERS Make sure the pipes are clean and free of obstructions, dirt, and piping compound. A battery requires one or two connections of appropriate size for the gas requirement. Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution. Do not use an open flame. After piping has been checked for leaks, fully purge gas pipes to remove air. GAS PRESSURES (ALL MODELS): The gas pressure should be set at 4” W.C. (Water Column) (0.
LG SERIES GAS FRYERS When installing a quick disconnect you must also install a means for limiting the movement of the fryer. This device will prevent the gas line or quick disconnect from being strained. The restraining device should be attached to the cutout on the back panel. See illustration for location. In Australia, use only the caster supplied by the manufacturer for the fryer device.
LG SERIES GAS FRYERS OPERATION Hot oil and parts can cause burns. Use care when operating, cleaning and servicing the fryer. Spilling hot frying compound can cause severe burns. Do not move fryer without draining all frying compound from the tank. OVER-TEMPERATURE SHUTDOWN If the shortening becomes overheated, a high-temperature shutoff device will turn the gas valve off and extinguish the pilot.
LG SERIES GAS FRYERS FILLING TANK WITH SHORTENING Solid shortening should NOT be used with LG300 fryers. Melting solid shortening will damage the tank and void your warranty. Close the drain valve. Fill the fryer tank with liquid shortening. Shortening level should be between the min and max lines in the fryer tank. Shortening will expand when heated. Do not ill the fryer tank past the MAX line. Add fresh shortening as needed to maintain oil level. VULCAN-HART F-32910 Rev.
LG SERIES GAS FRYERS LIGHTING THE PILOT 1. Open the door. 2. Turn the thermostat OFF (see figure below, view A). The thermostat is located behind the door. 3. Push the gas control valve knob and turn to OFF. Wait 5 minutes for unburned gas to vent. 4. Push and turn gas control valve knob to the “L” in PILOT (see figure below, view B). 5. While still holding the knob in, light the pilot with a lit flame. Continue to depress the knob until pilot remains lit when knob is released.
LG SERIES GAS FRYERS TURNING ON THE FRYER Set the temperature knob to desired temperature. After the set temperature has been reached, the thermostat shuts off the gas flow to burners. The pilot remains lit. The burners will cycle on and off, maintaining the set temperature. TURNING OFF THE FRYER 1. Turn the thermostat OFF. 2. To keep the pilot lit, turn the gas valve to “L” in Pilot. 3. To shut off all gas to the system, including the pilot, turn the gas valve knob to OFF. EXTENDED SHUTDOWN 1.
LG SERIES GAS FRYERS Fry Basket Guidelines Do not overfill baskets. (See table for recommended basket capacities below) Carefully lower basket into oil. When frying doughnuts and fritters, turn product only once during frying. When cooking French fries or onion rings, shake the basket several times. Batter-covered foods should be dropped carefully, one by one, into shortening or basket. If you use the basket, first dip the basket into the shortening to reduce batter-build up on basket surfaces.
LG SERIES GAS FRYERS DRAINING THE TANK 1. Turn the thermostat to OFF. 2. To keep the pilot lit, turn the gas valve to PILOT. 3. Direct the drain spout into the container that you want to drain the shortening into. 4. Open the drain valve. The oil will drain into the container. When the container is full or the fryer tank is empty, close the drain valve. Repeat this step until the fryer is empty. 5. If desired, perform the weekly clean-out as described under CLEANING. 6.
LG SERIES GAS FRYERS CLEANING Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer. Daily Clean your fryer regularly with the tank brush along with a damp cloth, and polish with a soft dry cloth. If regular cleaning is neglected, grease will be burned on and discolorations may form. Fingerprints are sometimes a problem on highly polished surfaces of stainless steel. They can be minimized by applying a cleaner that will leave a thin oily or waxy film.
LG SERIES GAS FRYERS Remove discolorations by washing with any detergent or soap and water. Use a self-soaping, non-metallic scouring pad for particularly stubborn discolorations. Always rub with the grain of the stainless steel. Do not use a metallic scoring pad or harsh cleaners. BOIL OUT PROCEDURE Weekly or as required: 1. Drain the tank as described under DRAINING THE TANK. 2.
LG SERIES GAS FRYERS MAINTENANCE Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer. Spilling hot fryer compound can cause severe burns. Do not move fryer without draining all frying compound from the tank. FLUE VENT INSPECTION When the fryer is cool, inspect annually. Check the flue and clear any obstructions.
