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
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 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 10). 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.
Injector sizes required for various gas types are shown in
Table 3 (page 14). 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.
