Setting up the Range Cooker
for Use
Regulation of the hob burner minimum flow rates
1. Natural gas
Light the burner and turn it to the minimum position.
Remove the gas control knob and turn the adjustment
screw at the side of the valve shaft until the required
minimum flame is achieved.
2. LPG
Remove the gas control knob and turn the adjustment
screw at the side of the valve shaft fully clockwise.
Once the above is complete, refit the knob and verify that the
burner flame is stable (the flame must not extinguish when
turning the control knob rapidly between maximum and
minimum position). Leave the control knob at the minimum
position for one minute to check the flame failure device
function. The flame should not extinguish. Repeat this process
for all hob burner controls.
Final installation checks
1. Check that all connections are gas tight using appropriate
methods and that the flexible gas hose is positioned
correctly, hanging freely, is not kinked or trapped and is not
in contact with any sharp edges including unfinished
cabinet materials.
2. Check that the supply pressure is correct for the type of gas
being used (Natural Gas 20mbar, Butane 28-30mbar,
Propane 37mbar).
3. Check the correct functioning of all burners at nominal and
reduced rates.
