GRDF / GRCF 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.
GRDF / GRCF SERIES GAS FRYERS UNPACKING This fryer was carefully inspected before leaving the factory. Upon acceptance of the shipment, the transportation company assumes full responsibility for safe delivery. Immediately after unpacking the fryer, check for possible shipping damage. If the fryer is damaged, save the packaging material and contact the carrier within 15 days of delivery.
GRDF / GRCF SERIES GAS FRYERS Clearances Minimum clearance from combustible construction: 6” (15 cm) from the sides of the fryer 6” (15 cm) from the back of the fryer The fryer may be installed on combustible floors Minimum clearance from noncombustible construction: 0” from the sides of the fryer 0” from the back of the fryer Between the fryer and any open-top flame units: 16” (41 cm) Allow space for servicing and operation.
GRDF / GRCF SERIES GAS FRYERS In the commonwealth of Massachusetts all gas appliances vented through a ventilation hood or exhaust system with a damper or with a power means of exhaust shall comply with 248 CMR. In Canada: Local codes CAN/CSA-B149.1 Natural Gas Installation (latest edition). CAN/CSA-B149.2 Propane Installation Code (latest edition), available from the Canadian Gas Association 178 Rexdale Blvd., Etobicoke, Ontario Canada M9W 1R3. CSA C22.1 Canadian Electric Code L4W 5N6.
GRDF / GRCF 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.
GRDF / GRCF 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.
GRDF / GRCF SERIES GAS FRYERS LEVELING THE FRYER Check the level of the fryer by placing a level on top of the fryer after gas connections have been made. Ensure that the fryer is level front-to-back and side-to-side in the final installed position. If using casters, lock the wheels after unit is level. 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.
GRDF / GRCF SERIES GAS FRYERS FILLING TANK WITH SHORTENING 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 fill the fryer tank past the MAX line. Add fresh shortening as needed to maintain oil level. BASIC FRYING INSTRUCTION Set the desired temperature and allow shortening to heat up to that temperature.
GRDF / GRCF 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.
GRDF / GRCF SERIES GAS FRYERS Programming the Solid State Control 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. Turn the thermostat knob to OFF. 2. Push in the pilot knob and turn to OFF. 3. Thoroughly drain the fryer. Refer to DRAINING THE FRYER. 4. Clean the fryer according to CLEANING. 5. Turn off the main gas shutoff valve.

GRDF / GRCF SERIES GAS FRYERS FILTERING THE OIL Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer. Filter shortening at least once a day. 1. Do NOT turn off the power to the fryer. Leave power on. 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. A cold fryer will not drain properly. Always filter shortening between 250°F and 350°F.
GRDF / GRCF SERIES GAS FRYERS 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. Remove the drain extension and place it back into the provided holder. 5. It is recommended to now Boil Out your fry tank. Follow the Boil Out procedure.
GRDF / GRCF SERIES GAS FRYERS 8. Turn OFF the power to the fryer. Drain the tank according to DRAINING THE TANK. Rinse thoroughly with clear, hot water. All traces of cleaner must be removed. Dry the tank thoroughly. 9. Close the drain valve and add shortening. Follow the FILLING TANK WITH SHORTENING procedure in this manual. The fryer is now ready for use. CLEANING Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer.

GRDF / GRCF 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.

GRDF / GRCF 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.
GRDF / GRCF 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. FILTERING PROCEDURE Oil Temperature should be 300-350° F.

GRDF / GRCF SERIES GAS FRYERS FILTERING TIP: Open the filtering drawer approximately 1” to allow any oil in the return line to run back into the filter pan. This will take about 30 seconds to complete. Then open the drawer completely to clean filter components. REMOVING EXCESS DEBRIS FROM THE SCREEN FILTER: 1. Pull the filter drawer out and remove the crumb basket and empty any debris into the trash. 2. Remove the filter screen assembly. Scrape debris from the filter screen.
GRDF / GRCF SERIES GAS FRYERS BOIL OUT PROCEDURE: Use the Boil Out By-Pass™ drain extension allowing the boil out solution to exit the fry tank without using the filtering system. Do not allow water to run through the motor / pump. Drain the boil out solution into a bucket or place a hose on the end of the drain extension allowing the other end to flow into a floor drain. In Fig. 6 the arrow is pointing to the drain extension. It is threaded into the top coupling of the oil drain tube.
GRDF / GRCF 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.
