OPERATION
FILLING TANK WITH OIL
NOTICE Solid shortening or oil must NOT be used with these fryers. Melting solid shortening or oil will damage the tank and void your warranty.

- Close the drain valve.
- Fill the fryer tank with liquid oil.
- Oil level should be between the min and max lines in the fryer tank.
- Oil will expand when heated. Do not fill the fryer tank past the MAX line.
- Add fresh shortening as needed to maintain oil level.
LIGHTING THE PILOT

- Open the door.
- Turn the thermostat OFF. The thermostat is located behind the door.
- Push the gas control valve knob and turn to OFF position. Wait 5 minutes for unburned gas to vent.
- Push and turn gas control valve knob to the “L” in PILOT.
- 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. If the pilot does not remain lit, repeat steps 3 through 5.
- Depress and turn gas control knob to ON.
- If gas supply is interrupted, repeat steps 2 through 6.
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 the burners.
- The pilot remains lit. The burners will cycle on and off, maintaining the set temperature.
TURNING OFF THE FRYER
- Turn the thermostat OFF.
- To keep the pilot light, turn the gas valve to “L” in PILOT.
- To shut off all gas to the system, including the pilot, turn the gas valve knob to OFF.
WARNINGS - OVER-TEMPERATURE SHUTDOWN
If the oil 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 re-light the pilot until the oil temperature is below 300℉ (149℃).
EXTENDED SHUTDOWN
- Turn the thermostat knob to OFF.
- Push in the gas valve knob and turn to OFF.
- Thoroughly drain the fryer. Refer to DRAINING THE TANK.
- Clean the fryer according to the CLEANING instruction section.
- Turn off the main gas shutoff valve.
EXTENDING OIL LIFE
Oil life can be extended by the following guidelines:
- Do not salt food over the fryer.
- Use good quality oil.
- Filter oil daily (at a minimum).
- Replace oil if it becomes poorly flavored.
- Keep equipment and surrounding area clean. Use tank covers when not in use. (accessory purchased separately).
- Set thermostat correctly.
- Remove excess moisture and particles from food products before placing them in fryer.
- Use a fitted tank cover (accessory purchased separately) to keep oil covered from light and oxygen.
DRAINING THE TANK
Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer.
- Turn the thermostat knob to the OFF position.
- Insert the drain extension into the drain valve. Hand tighten only.
- Direct the drain extension into the mobile filtering device that you want to use.
- 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.
- When fry tank is empty use a tank brush to remove any additional debris.
- Close the drain valve.
- Fill tank with new oil. Fill to a minimum of the MIN level but no higher than halfway between MIN and MAX. Oil will expand as it is heated.
- After the fry tank is filled with new oil, turn the thermostat knob to the desired set temperature. The burners will come on and will heat the oil.
Notice for Cleaning
NOTICE To maintain cleanliness and increase service life, the fryer should be cleaned daily. Do not immerse in water or any other liquid, if liquid enters the electrical compartment, it may cause a short circuit or electrical shock.
NOTICE Do not use chlorine or sulfate/sulfide cleaners.
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 discoloration may occur.
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.
- Clean all exterior surfaces of your fryer at least once daily.
- Use a damp cloth with warm water and a mild soap or detergent.
BOIL OUT PROCEDURE:
- Drain the tank as described under DRAINING THE OIL.
- Once the oil has been drained, flush out scraps and sediment using the provided tank brush.
- Close the drain valve and fill the tank with water. Use a low foaming cleaner/degreaser to clean the fry tank. Follow the instructions on the package.
- Solution level must be between the MIN and MAX levels on the fryer tank.
- Set the temperature knob to 200°F or for the recommended solution being used. Allow solution to simmer for about 15 to 20 minutes.
- Drain the cleaning solution from the tank.
- 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.
- Bring the solution to a simmer only, turn the thermostat off. Allow to stand for a few minutes.
- Drain the tank according to DRAINING THE OIL. Rinse thoroughly with clear, hot water. All traces of cleaner must be removed. Dry the tank thoroughly.
- Close the drain valve and add oil. Follow the FILLING TANK WITH OIL procedure in this manual. The fryer is now ready for use.
