GRM SERIES GAS FRYERS In Canada: Local codes CAN/CSA-B149.1 Natural Gas and Propane Installation Code (latest edition),available from the Canadian Standards Association, 155 Queen Street, Suite 1300, Ottawa, Ontario Canada K1P 6L1. CSA C22.1 Canadian Electric Code (latest edition), available from the Canadian Standards Association, 155 Queen Street, Suite 1300, Ottawa, Ontario Canada K1P 6L1. ASSEMBLY The fryer must be restrained to prevent tipping and the splashing of hot liquid.
GRM SERIES GAS FRYERS GAS CONNECTION All gas supply connections and any pipe joint compound must be resistant to the action of propane gases. The gas inlet is located on the lower rear of the fryer. Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer. The gas supply line must be at least the equivalent of ½” (12.7 mm) iron pipe for single units and 1-1/4” (31.75 mm) for batteries.
GRM SERIES GAS FRYERS The fryer must be installed with a connector (not supplied by Vulcan) complying with the above codes. The fryer must be installed with restraining means to guard against transmission of strain to the connector. See illustration. The fryer must be installed with the casters provided. If the restraint is ever to be disconnected, first turn the gas supply off.
GRM SERIES GAS FRYERS OVER-TEMPERATURE SHUTDOWN If the shortening becomes overheated, a high-temperature shutoff device will turn the gas valve off and extinguish the pilot. If the fryer shuts down due to overheating, DO NOT relight the pilot until the shortening temperature is below 300 F (149 C). If an overheating situation persists, contact your local Vulcan-Hart authorized service office.
GRM SERIES GAS FRYERS 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. LIGHTING THE PILOT A B A Thermostat Knob B Gas Control Handle 1. Open the door. 2. Turn the thermostat to OFF (see figure below, view A). The thermostat is located behind the door. 3.
GRM 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 the OFF position.
GRM SERIES GAS FRYERS Drain or wipe dry raw or wet foods to minimize splatter when lowering into hot shortening. Add fresh shortening as needed. 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.
GRM SERIES GAS FRYERS DRAINING THE OIL – Free Standing Fryers Only Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer. 1. Turn the thermostat knob to the OFF position. . 2. Insert the drain extension into the drain valve. Tighten only hand tight. 3. Direct the drain extension into the mobile filtering device that you want to use. 4. Slowly open the drain valve to allow oil to flow from the fry tank to the filter pan. Then open the drain valve all the way. 5.
GRM 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.
GRM SERIES GAS FRYERS 5. Set the temperature knob to 200°F or for the recommended solution being used. Allow solution to simmer for about 15 to 20 minutes. 6. Drain the cleaning solution from the tank. 7. Close the drain valve and refill the tank with water. Add 1 cup (1/4 L) of vinegar to neutralize alkaline left by the cleaner. Solution level must be between the MIN and MAX level on the fryer tank. 8. Bring the solution to a simmer only, turn the thermostat off. Allow to stand for a few minutes. 9.
GRM SERIES GAS FRYERS Filtering Instructions for KleenScreen PLUS® Fryers General The KleenScreen PLUS® filtration system filters the oil as it is pumped back into its’ respective tank(s). Only one tank can be drained and filtered at a time. Under no circumstances should both tanks be drained at the same time. Assembly After unpacking, wash the filter pan, crumb basket and filter screen assembly. Make sure you remove the insert located inside the filter screen.

GRM SERIES GAS FRYERS INSTRUCTIONS TO REMOVE & REPLACE KLEENSCREEN PLUS® FILTER ENVELOPE FOR ABSOLUTE FILTRATION & MAXIMUM FLOW RATE WE RECOMMEND YOU CHANGE YOUR FILTER ENVELOPES AT EVERY OIL CHANGE (10-14 DAYS DEPENDING ON OIL USAGE). Step 1 Discard all oil from the filter vessel, (see pages 23 or 24). When the filter pan is empty, use a spatula and scrape off all debris left on the filter envelope and in the filter pan.
GRM 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. Never run water or boil out solution through filter and motor / pump. Doing so will void your fryer warranty. Solid shortening should NOT be used with GRM fryers. Melting solid shortening will damage the tank and void your warranty.
GRM SERIES GAS FRYERS 4. Drain the oil out of the fry tank by turning the red handle drain valve. The filter pan will begin to fill with oil. When the oil level fills half of the filter pan, pull the red handled filter lever towards you. The motor / pump will begin and oil will flow back into the fry tank. The oil will flow into the back of the tank towards the front and down the drain back into the filter pan.
GRM SERIES GAS FRYERS FLUSH AND DISCARD: 1. Follow filtering instructions 1-3, however do not put oil treatment media into the fryer. Drain the fryer oil into the filter pan. 2.
