3.1 Filling the Fryer
- Ensure the drain valve is closed.
- Fill the fryer tank with cooking oil to the "MIN" oil level mark, but not exceeding the "MAX" mark. The fryer has a 40 lb oil capacity.
3.2 Lighting the Pilot
- Turn the main gas valve to the "OFF" position. Wait five minutes to clear any gas.
- Turn the thermostat knob to the "OFF" position.
- Push in the pilot knob and turn it to the "PILOT" position. Continue to hold the knob in.
- While holding the pilot knob in, use a lit match or igniter to light the pilot burner.
- Once the pilot is lit, continue to hold the pilot knob in for approximately 30-60 seconds, then release. The pilot should remain lit. If it extinguishes, repeat the process.
- Turn the pilot knob to the "ON" position.
3.3 Main Burner Operation
- With the pilot lit, turn the thermostat knob to the desired frying temperature.
- The main burners will ignite automatically. The burners will cycle on and off to maintain the set temperature.
3.4 Frying Procedure
- Ensure oil is at the desired temperature before adding food.
- Load food into the fry baskets. Do not overload baskets, as this can lower oil temperature and result in soggy food.
- Carefully lower baskets into the hot oil.
- Cook food until golden brown and thoroughly cooked.
- Lift baskets and allow excess oil to drain back into the tank.
- Empty cooked food into a holding pan.
3.5 Shutting Down
- Turn the thermostat knob to the "OFF" position.

4.2 Oil Filtration and Replacement
Filter your cooking oil daily to extend its life and maintain food quality. Replace oil regularly based on usage and food quality. When replacing oil, drain the old oil completely into a suitable container. Clean the tank before refilling with fresh oil.
4.3 Boil-Out Procedure (Weekly/As Needed)
- Drain all oil from the fryer tank.
- Close the drain valve.
