4. Operating Instructions

4.1 Lighting the Pilot

1. Ensure the main gas supply valve to the fryer is open.
2. Turn the thermostat knob to the "PILOT" position.
3. Press and hold the red ignition button (or pilot button) while simultaneously lighting the pilot burner with a long match or lighter.
4. Continue to hold the button for approximately 30-60 seconds after the pilot ignites to allow the thermocouple to heat up.
5. Release the button. If the pilot extinguishes, repeat the process.

2. The main burners will ignite automatically and heat the oil to the set temperature.
3. Allow sufficient time for the oil to reach the target temperature before adding food.

4.3 Frying Procedure

• Do not overload the fry baskets. Fry in small batches to maintain oil temperature and ensure even cooking.
• Carefully lower baskets into the hot oil to prevent splashing.
• Monitor cooking progress and remove food when golden brown and cooked through.
• Shake off excess oil before serving.

4.4 Shut Down

• At the end of operation, turn the thermostat knob to the "OFF" position.
• For extended periods of non-use, turn off the main gas supply valve to the fryer.

5. Maintenance

5.1 Daily Cleaning

• Crumb Removal: Use the full port drain to remove crumbs and sediment from the bottom of the fry pot.
• Exterior Cleaning: Wipe down all stainless steel surfaces with a damp cloth and mild detergent. Dry thoroughly to prevent water spots.

5.2 Deep Cleaning (Weekly/Bi-Weekly)

• Drain all oil from the fry pot.

• Rinse thoroughly with clean water multiple times until all cleaning solution residue is removed. Dry completely.

5.3 Burner and Pilot Maintenance
