4. Operation
Follow these steps for safe and effective operation of your Vulcan LG400-2 fryer.
4.1 Filling the Fry Tank
- Ensure the 1-1/4" full port ball type drain valve is closed.
- Fill the 14"W x 14"L fry tank with 45-50 pounds of cooking oil to the indicated fill line. Do not overfill or underfill.
4.2 Ignition and Temperature Control
- Turn on the main gas supply to the fryer.
- The fryer features a millivolt thermostat control. Turn the control knob to the desired temperature, ranging from 200°F to 400°F.
- The pilot light must be lit for the main burners to ignite. Refer to the label on the fryer for pilot lighting instructions.
- Allow the oil to preheat to the set temperature. This may take several minutes.
4.3 Frying Procedures
- Place food items into the twin fry baskets. Do not overload the baskets, as this can lower oil temperature and result in soggy food.
- Carefully lower the baskets into the hot oil.
- The large "V" shaped cold zone at the bottom of the tank helps collect food particles, extending oil life and improving food quality.
- Once cooking is complete, raise the baskets and allow excess oil to drain using the drain extension.
- The easy removable basket hanger allows for convenient storage of baskets when not in use.
4.4 Shutting Down
- Turn the thermostat control knob to the "OFF" position.
- For complete shutdown, turn off the main gas supply valve to the appliance.

Regular cleaning and maintenance are crucial for the longevity and efficient operation of your fryer.
5.1 Daily Cleaning
- Oil Draining: After the oil has cooled completely, open the 1-1/4" full port ball type drain valve to drain the oil into a suitable container.
- Tank Cleaning: Once the oil is drained, clean the interior of the fry tank with warm, soapy water and a non-abrasive brush or cloth. Rinse thoroughly and dry completely.
- Basket Cleaning: Wash the fry baskets with warm, soapy water and rinse.
- Exterior Cleaning: Wipe down the stainless steel fry tank, front, top, and door with a damp cloth and mild detergent. Dry immediately to prevent streaks.
5.2 Oil Filtration/Replacement
