Usage Features
Installation and Commissioning:
- Must be installed, commissioned, serviced, and converted by a qualified person according to national and local regulations.
- Requires installation on a level surface with unobstructed vents.
- Minimum distances: 50mm (A) and 1000mm (B) as shown in Fig 1.
- Should be sited beneath an extraction canopy for combustion product removal.
- Requires sufficient ventilation with a minimum free area of 4.5cm² per kW of total heat input.
- An equipotential bonding terminal is provided for cross-bonding with other equipment.
- The J5 model includes a stability kit for floor fixing.
- Commissioning involves checking all controls, calibrating the thermostat, and verifying oil temperature after main burners cut out.
- Operators must be trained on safe lighting, operation, and shutdown, and aware of the isolating cock.
Operator Precautions:
- Do not leave unattended during operation.
- Never put water in oil; drain food of excess moisture before frying.
- Avoid overloading baskets.
- Do not use the dust cover lid during operation.
- Allow oil/fat to cool before replenishing; do not add cold oil to hot oil while cooking.
- Install a suitable fire extinguisher and blanket nearby.
- Do not use flammable solvents or cleaning aids.
- Strip plastic coating and clean before first use.
Notes on Frying:
- Good quality vegetable oil is recommended for higher smoke/fire temperature and less taint.
- Oil life is extended by regular filtering and using standby mode when not in use.
- Old oil is more prone to boil/surge, has a lower flashpoint, and can overheat. Frequent oil changes reduce fire risk.
- Defrost frozen food first to maintain heating recovery time and output.
- Always allow oil to reach temperature before adding product.
Preparation for Use:
- Ensure drain valves are closed.
- Fill tanks with water and mild detergent to the lower indicated mark on the batter plate.
- Boil water for a short time, then switch off and drain.
- Rinse and dry the tank thoroughly.
- Run a small quantity of oil around the tank and drain to remove residual water and coat the tank.
- Close the drain valve, fit the blanking nut, and fill with clean oil to the lower level, maintaining oil at the upper level during service.
Lighting:
- Ensure the supply isolation valve is open.
- Turn the control knob to the 'Off' position.
- Push in and turn anticlockwise to the pilot position; the piezo igniter will click to ignite the pilot.
- Hold the knob depressed for 20 seconds to establish the pilot flame. If it fails, return to 'Off', allow reset time, and repeat.
- To operate the main burner, turn the control knob to the operating position and the thermostat control knob to the required setting.
- If the burner fails, the valve may enter 'lockout' mode.
Standby:
- The appliance can be left on standby by lighting the pilot and leaving the control knob in the pilot position. The main burner will not operate in this mode.
Safety Cut-out:
- If the safety thermostat operates, the appliance will shut down. Allow oil to cool before resetting by depressing the red button.
Shut Down:
- For temporary shutdown, turn the control knob to the pilot position to shut down the main burner while keeping the pilot lit.
- For full shutdown, turn the control knob to 'Off' and shut off the gas supply.
Drainage:
- Allow oil to cool below 55°C before draining.
- Remove the blanking nut from the front, fit the drain tube, and place a receptacle underneath.
- Lift the drain valve handle lock to operate the drain valve, then move the handle forwards and upwards to drain.
- Close the valve, remove the pipe, and refit the blanking nut.
- Remove excess oil with kitchen paper.
- Ensure the handle lock is in position before refilling.
Maintenance Features
Cleaning:
- Do not use a water jet or steam cleaner, or immerse the appliance.
- Drain as per instructions.
- Clean all panels with warm water and mild detergent; avoid abrasive or flammable materials. Dry with a soft cloth.
- Clean drain valves from inside and outside with a tube or flue brush.
Servicing, Maintenance, and Component Replacement:
- All servicing, maintenance, and component replacement must be carried out by recommended service engineers.
Routine Service Checks:
- Verify correct hose usage and condition, replacing if necessary.
- Check for a fitted safety chain.
- Confirm the presence of a separate isolation valve.
- Inspect burner operation, flame picture, and for debris/damage.
- Check pilot flame correctness and clean pilot components if needed.
- Test safety thermostat operation.
- Observe that the flue is clear.
- Perform a gas soundness check.
Component Replacement (Access via ignition assembly removal):
- Igniter electrode and Pilot jet: Remove the ignition assembly, disconnect the igniter lead, remove the screw holding the electrode. Reassemble in reverse, ensuring the pilot jet is refitted.
- Thermocouple: Remove the ignition assembly, undo the nut securing the thermocouple to the pilot body, pull down. Undo the nut holding the thermocouple into the valve, disconnect wiring from the interrupter thermocouple block. Replace and reassemble.
- Multi Function Control Valve (M.F.C.): Undo two screws and remove the M.F.C. cover plate. Disconnect wires from the interrupter, then the thermocouple. Remove the interrupter, then disconnect all pipework (pilot, gas supply, burner). Disconnect the ignition lead. Locate and remove the retaining screw in the lower rear of the M.F.C. valve. Transfer compression fittings from old to new valve, fit supplied blanking plugs. Reassemble in reverse.
- Safety Thermostat: Drain oil. Remove thermostat phial cover and securing bracket. Remove fascia panel. Undo gland nut at front of tank. Carefully withdraw phial. Undo two screws and remove M.F.C. cover plate. Slide up cover to access capillaries for removal/refitting. Disconnect wiring from thermostat. Undo locknut from thermostat body. Reassemble in reverse.
Conversion of Gas Type:
- This process is only permitted by qualified, registered personnel.
- Involves replacing specific components such as fibre washers, copper washers, pilot jets, burner jets, aeration plates, and updating data plates and labels.
- After conversion, the appliance must be functionally operated to the new operating pressure as detailed on page 4.
Fault Finding:
The manual includes flowcharts for diagnosing common issues:
- Piezo igniter not sparking: Checks electrode alignment, high tension lead for shorts, and electrode insulator for fractures.
- Pilot burner will not light or stay lit: Checks thermocouple/interrupter connections, gas presence at pilot, safety thermostat for open circuit, thermocouple voltage, pilot injector for blockage, and suggests control valve fault if all else is correct.
- Main burner will not light: Checks control knob position, safety thermostat operation, and continuity through the thermostat.
- Safety thermostat operates: Checks if oil temperature is over 200°C, if control thermostat operates on temperature rise when set point is low (100°C), and if connections on the gas control are correct.
