OPERATIONS TO BE PERFORMED WHEN CONVERTING GAS TYPES
This operation can only be performed by an authorized person.
Remove the gratings and the burner covers;
Using a spanner, replace the nozzle injectors “J” (Fig.20) with either Natural
Gas sized injectors or LPG sized injectors. Ensure you replace the
corresponding gas type label on the appliance after conversion.
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.
Ensure the operation of the appliance is fully tested after cooktop installation is complete.
NOTE: If an appliance cannot be adjusted to perform correctly, contact your nearest service department.
