CHECKING THE BURNER PRESSURE
Natural Gas (the appliance test point is located at
the regulator). The supplied regulator must be fitted
to the appliance inlet connection. The gas pressure
must be adjusted to 1.0kPa when approximately
50% of the burners are on high.
Universal LPG (the appliance test point is
located at the injector). The gas pressure
must be checked to confirm the appliance
operating pressure is 2.75kPa. The appliance
test point is the rapid burner injector.
1. Disconnect the electrical power.
2. Light the auxiliary burner and set to high.
Make sure all other burners are off.
3. Zero the manometer, fix the flexible tubing
to seal around the rapid burner injector and
hold in place. Check the gas pressure by
pressure by pressing in the corresponding
burner control knob down and turning to the high position.
4. If the pressure is 2.75kPa, reassemble the burner and perform the final checks as per this manual.
5. If the pressure is not 2.75 kPa, disconnect the appliance and check/adjust/replace the ULPG cylinder
regulator(s) as appropriate in accordance with AS/NZS 5601.
Alternatively, if the appliance is supplied with a ULPG test point adapter, then this can be fitted to the inlet
connection for the purpose of a test point.
REGULATING THE BURNER MINIMUM SETTING
When switching from one type of gas to another, the
minimum flow rate must also be correct. The flame
should not go out even when passing suddenly from
maximum to minimum flame. To regulate the flame,
follow the instructions below:
Light the burner
Set the gas valve to minimum
On gas valves provided with adjustment screw in the
centre of the shaft (fig.21)
Using a screwdriver with max. diameter 3mm, turn the
screw inside the tap until the correct setting is obtained.
On gas valves provided with adjustment screw on the valve body (fig.22):
Turn the screw “A” to the correct setting with a screwdriver.
LUBRICATION OF THE GAS TAPS
This can only be performed by an authorised person. It may be required if the gas taps become stiff and
difficult to turn.
LEAK TESTING
1.
Make sure gas control knobs are Off and turn the cylinder valve On .
2.
Check for leaking joints by brushing with solution of half-liquid detergent and half water. If a leak is present,
bubbles will appear (or you may hear a hissing sound). Retightening connections can generally repair a leaking
joint. You must also check the gas hose and connection at the gas cylinder. If a leak cannot be resolved, do not
proceed.
DO NOT USE NAKED FLAME FOR LOCATING GAS LEAKS.
IF A LEAK PERSISTS CALL AN AUTHORISED GAS FITTER.
NOTE: If an appliance cannot be adjusted to perform correctly, contact your nearest service department
.
