This manual covers the installation, operation, and maintenance of Avantco Floor Fryers. These units are intended for commercial use only. Always ensure the unit is installed by a qualified technician to maintain warranty validity. Key safety precautions include keeping the area free of combustibles, ensuring proper ventilation, and never using an open flame to check for gas leaks.
Installation
Installation must conform to local codes and the National Fuel Gas Code. Follow these steps:
- Unpacking: Inspect for shipping damage immediately upon arrival.
- Legs and Casters: Install the provided legs or casters. Ensure the unit is level to maintain performance.
- Flue Installation: Assemble the flue box and flue wrap using the provided self-tapping screws.
- Clearances: Maintain at least 6 inches of clearance from combustible construction on sides and rear. Ensure at least 16 inches of space between the fryer and adjacent surface flames.
- Ventilation: The unit must be installed under a ventilation hood.
- Gas Connection: Connect to the appropriate gas type (Natural or Propane) as indicated on the serial plate. Use a 3/4" NPT male connector. Ensure manifold pressure is set to 4" W.C. for natural gas or 10" W.C. for propane.
Operation
Filling the Fry Pot: Close the drain valve completely. If using solid shortening, pack it into the zone below and between the heat tubes before lighting. Never melt solid shortening on top of the heat tubes.
Lighting Procedure:
- Open the front burner compartment door.
- Turn the thermostat to "OFF".
- Turn the combination gas valve knob to "PILOT".
- Press and hold the knob to release gas, then ignite the pilot light.
- Hold the knob for 30 seconds after ignition.
- Once the pilot stays lit, turn the knob to "ON".
- Turn the thermostat to the desired temperature only after the fry pot is filled with oil.
Cleaning
Daily Cleaning: Drain the fry pot, remove sediment, wipe the basket support frame and interior, and strain the oil. Refill to the MIN oil level mark.
Weekly Cleaning: Follow daily cleaning steps, then fill the pot with a solution of warm water and boil-out compound. Bring to a gentle boil for 5 minutes, scrub the walls and tubes, rinse, and dry.
Stainless Steel Surfaces: Clean with soap and water. Avoid using steel wool, wire brushes, or circular motions, which can damage the finish.
Service and Maintenance
Service should only be performed by qualified technicians. The manual provides instructions for checking and adjusting main burners, the pressure regulator, thermostat calibration, and the auto safety pilot. A wiring diagram is included for electrical troubleshooting.
Troubleshooting
If the burners do not ignite, check the gas supply, ensure the combination gas valve is not in the "OFF" position, and verify the pilot is lit. If the pilot will not stay lit, check for a bad thermopile, clogged orifice, or draft conditions.
