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 9). 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, please 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 10). Normally, this will have been
correctly set at the factory for use on Natural
Gas (NG) and should not require adjustment.
IMPORTANT:
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.
Figure 9
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 for assistance.
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.
CAUTION:
Servicing must only be carried out by
an authorised service person.
Injector sizes required for various gas types are
shown in Table 3 on page 18. 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.
