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 (

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
