Installation 2 Installation Requirements NOTE: • It is most important that this appliance is installed correctly and that operation is correct before use. Installation shall comply with local gas, health and safety requirements. • This appliance shall be installed with sufficient ventilation to prevent the occurrence of unacceptable concentrations of health harmful substances in the room, the appliance is installed in.
2 Installation Clearances NOTE: Only non-combustible materials can be used in close proximity to this appliance. Left/Right Hand Side Rear Combustible Surface Non Combustible Surface 50 mm 0 mm 50 mm 0 mm Assembly NOTE: • All Models are delivered completely assembled. No further assembly is required. • This appliance is fitted with adjustable feet to enable the appliance to be positioned securely and level. This should be carried out on completion of the gas connection.
Installation 2 The regulator connections are 3/4" BSP female. The connection to the appliance is 3/4" BSP male. (Refer to the “Specifications” section for the gas supply location dimensions). NOTE: A Manual Isolation Valve must be fitted to the individual appliance supply line. 4. 5. 6. Correctly locate the appliance into its final operating position and using a spirit level, adjust the legs so that the unit is level and at the correct height. Connect the gas supply to the appliance.
3 Operation 3.
Operation 3.2 3 Explanation of Control System Safety System Electromagnetic Flame Failure Gas Valve The purpose of the safety system is to shut off the flow of gas if the pilot flame goes out. It is comprised of the flame itself, the thermocouple, and the flame failure gas valve. The purpose of the safety valve is to shut off the flow of gas if the pilot flame goes out. Inside the body of the gas valve is an electromagnet connected to a spring loaded plunger.
4 Cleaning / Maintenance CAUTION: Always turn off the gas supply before cleaning. This unit is not water proof. Do not use water jet spray to clean interior or exterior of this appliance. Routine Maintenance To achieve the best results cleaning must be regular and thorough and all controls and mechanical parts checked and adjusted periodically by a competent serviceman. If any small faults occur, have them attended to promptly. Don't wait until they cause a complete breakdown.
Cleaning / Maintenance 4 Daily Cleaning 1. 2. 3. 4. The grease drawer should be checked and emptied frequently to prevent overflow and spillage. Remove the grease drawer while still warm so that the grease is in a liquid state. Empty any grease from the drawer and wash thoroughly in the same manner as any cooking utensil. Thoroughly clean the splash back, the interior and exterior surfaces of the range with hot water, a detergent solution and a soft scrubbing brush.
4 Cleaning / Maintenance Griddle - Chrome Plate C AUTI ON Always ensure that an even pressure is applied over the whole surface of the scraper tool when using on the flat chromed surface of the griddle, to prevent scoring of the surface. NEVER bang the sharp edge of the scraper tool on the flat chromed surface of the griddle as this will damage the chrome finish and invalidate the warranty.
Trouble-shooting WARNING: 5.1 5 ALL INSTALLATION AND SERVICE REPAIR WORK MUST BE CARRIED OUT BY QUALIFIED PERSONS ONLY. Trouble Shooting Chart Fault Pilot won’t light Piezo ignitor not sparking. Pilot flame small / lazy / yellow. Pilot goes out when knob released. Possible cause Remedy Gas control knob not being held in. Hold in button while lighting pilot. No gas supply. Ensure gas is connected and on (bottles not empty). Gas pressure too low. Check gas supply pressure.
5 Trouble-shooting Fault Main burner flame incorrect colour (yellow / wavy). Pilot goes out when main burner comes on. Possible cause Remedy Aeration setting incorrect. Adjust aeration. (Refer service section 6.4.4) Incorrect gas pressure. Check supply pressure. Incorrect injector size. Check injector correct size. Obstruction in burner. Inspect burner for obstruction. Incorrect gas pressure. Check supply / adjust pressure. (Refer specifications section) Faulty gas control.
Trouble-shooting 5.2.2 5.2 Fault diagnosis 5.2.1 Pilot goes out when pilot knob is released 5 Piezo ignitor not sparking Short in high tension lead If repeated sparking of the piezo shows intermittent sparking at the electrode, then the lead should be traced to find area of short. This can normally be visually seen as the spark arcs. If the lead is shorting the best solution is to replace it, as the electrical insulation strength of the lead may have deteriorated.
