TESTING APPLIANCE OPERATION
After installation, test the appliance and ensure that it operates correctly before handing it over to the customer. The following procedure is recommended:
1.Turn on the gas and electricity supply and attempt ignition on all burners, both separately and in combination. (For correct procedure, refer to page 4).
Note that additional time needs to be allowed for the initial lighting as air has to be purged from the pipes.
2.Observe the flame appearance on each burner.
(Figure 11) If it is much larger or much smaller than expected, the injector size and supply pressure require checking. Where a flame is unsatisfactory, refer to the Troubleshooting Guide (Page 6) to correct the fault. If the Troubleshooting Guide does not solve the problem, call the Service Centre.
3.When all the foregoing is satisfactory, check the turndown (minimum or low) setting on each burner, as this may need adjustment. Valves have a by pass controlling screw, which may be accessed by removing the knob. This screw will be located on a particular area of the valve. (Refer figure 12). Normally, this will have been correctly set at the factory for use on NG (Natural Gas) and should not require adjustment.
If the appliance has been converted to LPG, then the bypass screw will have to be screwed in until a small, stable flame results.
Please ensure the supply pressure has been checked PRIOR to any adjustment.
4.If the appliance cannot be adjusted to perform safely, inform the customer of the problem and affix an appropriate warning notice to the appliance. If the fault appears to be dangerous the appliance should be disconnected. If a minor fault exists, the customer may wish to use the appliance while awaiting service. If a fault cannot be fixed, please call the Service Centre.
5.The customer should be advised that, in the event of a fault, the local Service Organisation or the retailer from whom the appliance was purchased should be contacted.
6.When satisfied that the unit is operating correctly, turn off and instruct the customer on correct operation as outlined in this booklet. Ask the customer to operate the controls to ensure that the correct procedure is understood.
WARNING
Servicing must only be carried out by an authorised service person.
Injector sizes required for various gas types are shown in Table 2 (page 11). The appliance inlet pressure for each gas type is also shown.
For model identification after installation, an additional data plate sticker has been provided. This sticker is to be stuck onto adjacent cabinetry.
