Installation 2 Installation Requirements NOTE: It is most important that this salamander is installed correctly and that operation is correct before use. Installation shall comply with local electrical, gas, health and safety requirements. Cobra Salamanders are designed to provide years of satisfactory service, and correct installation is essential to achieve the best performance, efficiency and trouble-free operation.
2 Installation 3. This appliance must be mounted onto a non-combustible wall or tailored stand, using the rear wall bracket and spacing screws provided. 4. Combustible walls must not protrude past the front of the appliance. 5. This appliance must not be mounted on a combustible surface or metal surface, as radiated heat will cause these surfaces to become extremely hot. 6. Caution should be taken as intense heat is emitted at the bottom front of the appliance. 7.
Installation 2 Wall Mounting (to non-combustible wall only) 1. Fix the wall mounting bracket to the wall with six screws, in such a position that the top of the bracket is level and at least 945mm (38”) above any surface beneath the unit. This will ensure that the bottom of the Salamander is at least 600mm (24”) above any surface. 2. Fit the two black plastic spacers to the top rear corners of the unit. Leave them unscrewed by approximately 5mm. 3.
2 Installation Gas Connection NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY A QUALIFIED SERVICE PERSON. 1. Cobra Salamanders do not require an electrical connection, as they function totally on the gas supply only. 2. It is essential that the gas supply is correct for the Salamander to be installed and that adequate supply pressure and volume are available. The following checks should be made before installation:a.
Installation 7. 2 Check all gas connections for leakages using soapy water or other gas detecting equipment. WARNING: DO 8. NOT USE A NAKED FLAME TO CHECK FOR GAS LEAKAGES . Check that the gas operating pressure is as shown in 'Specifications' section. NOTE: The operating pressure to be measured at the manifold test point and with both burners operating at the 'High Flame' setting. 9. Turn off the mains gas supply and bleed the gas out of the appliance gas lines. 10.
3 Operation NOTE: A full user’s Operation Manual is supplied with the product and can be used for further referencing of installation, operation and service. 3.1 Description of Controls 1. Cobra salamanders provide two independently controlled heat zones. 2. High speed grilling is provided by the two infrared gas burners in the ceiling of the grilling compartment. 3.
Operation 3.3 3.4 Racking Racking System 3 Explanation of the Control System Safety System The Rack System fitted to the Cobra Salamander is self-supporting when withdrawn, to allow easy loading of food. The installation of the rack is dependant on the cooking function required. The purpose of the safety system is to shut off the flow of gas if the main flame goes out. It comprises the flame itself, the thermocouple, and the flame failure gas valve.
3 Operation Electromagnetic Flame Failure Gas Valve The purpose of the safety valve is to shut off the flow of gas if the main flame goes out. Inside the body of the gas valve is an electromagnet connected to a spring loaded plunger. When the electromagnet is energized, it holds the plunger in, allowing gas to flow through the valve. When the electromagnet is de-energized, the plunger snaps to the closed position, stopping the flow of gas to the main burner.
Cleaning / Maintenance 4 C AUTIO N : 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 unit. 4.1 Cleaning General Enamelled Surfaces To achieve the best results cleaning must be regular and thorough. All controls and mechanical parts should be checked and adjusted periodically by a qualified service person. If any small faults occur, have them attended to promptly.
4 Cleaning / Maintenance Gas Control Valve Re-Greasing The gas control valve should be dismantled and greased every 6 months to ensure the correct operation of the gas control valve. To carry out this operation;• Remove the gas control knobs from the gas tap spindles by pulling the knobs away from the control panel. • Remove the crumb / drip tray from the appliance. • Remove the two screws on the underside of the control panel, securing the control panel to the hob.
Cleaning / Maintenance 4 COBRA GAS SALAMANDER - MAINTENANCE SCHEDULE Business Name and Address: Date: Phone: Clients Order No: Service Report No: Fax: Serial No: Serviceman: 9 Model: 1 Inspect exterior condition of the unit. 2 3 4a 4b 5 6 7 8 9 Check working gas pressure is correct to figures shown on rating plate. Inspect burner ceramic plaques for signs of cracking. Inspect thermocouples. Replace thermocouples (every 12 months). Check injectors are clean and free from blockages.
5 Fault Finding 5.1 Fault Finding Chart C AUTIO N : All installation and service repair work must be carried out by qualified persons only. Fault Main burners will not light. Possible Cause Remedy Wrong size or blocked injectors. Replace / clean the main injectors. (Refer service section 6.2.3) Incorrect gas supply pressure. Check gas supply pressure is correct. Faulty gas control valve. Replace the gas control valve. (Refer Service Section 6.2.4) Burner goes ‘Out’ when set to ‘Lo’.
Fault Finding 5.2 Fault Diagnosis 5.2.1 Burner Drops Out When Gas Knob Released 5 Thermocouple Faulty Check thermocouple connection to gas control is firm (loose connections will cause resistance in millivolt circuit and result in pilot outage). If connection is OK, then disconnect the thermocouple from the rear of the gas control, light the burner, and whilst holding the control knob in, and measure voltage between the thermocouple and earth (e.g. the body of the gas control).
6 Service Procedures WARNING: • ENSURE THAT THE GAS SUPPLY IS SWITCHED 'OFF' BEFORE COMMENCING SERVICING. • ALWAYS CHECK / TEST FOR GAS LEAKS ON COMPLETION OF SERVICING REPAIRS ON THE GAS SYSTEM. C AUTIO N : All installation and service repair work must be carried out by qualified persons only.
