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:
Turn on the gas and electricity supply and attempt
ignition on all burners, both separately and in
combination. (For correct procedure refer to page
8 Lighting Burners). Note that additional time needs
to be allowed for the initial lighting as air has to be
purged from the pipes.
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 11) to
correct the fault. If the Troubleshooting Guide does
not solve the problem, call the Service Centre.
When all the foregoing is satisfactory, check the
turndown (minimum or low) setting on each burner,
as this may need adjustment. Valves have a bypass
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 Natural Gas (NG) and should not require
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.
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
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.
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.
Servicing must only be carried out by an authorised
Injector sizes required for various gas types are shown in
Table 3 (page 26). The appliance test point 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.
