5.1.4 GAS PRESSURE REGULATOR
If the gas pressure is higher than that specified or is difficult
to regulate (not stable), install a gas pressure regulator
(accessory code 927225) in an easily accessed position
ahead of the appliance.
The pressure regulator should preferably be fitted horizontally,
to ensure the right outlet pressure:
•
“
1
” connection side gas from mains.
•
“
2
” pressure regulator;
•
“
3
” connection side gas towards the appliance;
The arrow on the regulator (
) shows the gas flow
direction.

AUSTRALIA:
the gas pressure regulator supplied with the
appliance must be fitted to the appliance inlet. Adjust the
test point pressure with all hob burners operating at maximum
setting as follow:
- 1.0 KPa for Natural gas
- 2.65 KPa for Propane gas
NB!
These models are designed and certified for use with
natural or propane gas.
5.1.5. CHECKING THE PRIMARY AIR SUPPLY
When the primary air supply is correctly adjusted, the flame
does not “float” with burner cold and there is no flareback
with burner hot.
• Undo screw “A” and position aerator “E” at distance “H”
given on the Table B, retighten screw “A” and seal with
paint (fig. 3A).
5.1.6 CONVERSION TO ANOTHER TYPE OF GAS
“Technical data/gas nozzles” Table B gives the type of nozzles
to be used when replacing those installed by the manufacturer
(the number is stamped on the nozzle body).
At the end of the procedure, carry out the following check-list:
