GAS CONVERSION AND ADJUSTMENT
When used with natural gas all burners have been preset at our
factory and further adjustment should not be necessary. Conversion
kits to other gases are available from the place of purchase. Do
not attempt to fit the conversion kit yourself. Conversion to LPG
should only be carried out by authorised personnel
REPLACEMENT OF THE INJECTORS
When required to operate on other gas replace the injectors in
accordance with information referred to in chart below (Fig.10).
In order to change the work-top injectors, it is necessary to act
as follows:
- remove the grids
- remove burners and flame-spreaders
- change the injector (see Fig. 8) and replace it with another one
suitable for the new type of gas.
SPECIAL NOTE
When converting from Natural Gas to U-LPG ensure that the NG
regulator is removed and replaced with the Test Point Assembly.
A gas regulator suitable for a supply pressure of 2,75kPa should
be part of the gas tank supply.
After installation or any servicing operation, always ensure that
the appliance is gas sound and that the components are now
operating correctly. Items removed during servicing should be
replaced in the reverse order to their removal.
LOW POSITION ADJUSTMENT
- Switch the burner on, and turn the knob towards the minimum
flow position (small flame).
- Remove the knob from the tap.
- Introduce a little screwdriver in the tap rod (see picture).
Attention: in taps with security valve, the minimum adjusting screw
(A) is placed outside the rod tap (see fig. 7).
