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 12) 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. Once all the previous tests are 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 13).
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.
