4. FINAL OPERATIONS
After changing the nozzles, put the pan stands, the burner caps and flame diffuser rings back in
place.
After adjusting for use of a gas other than the gas used for testing the appliance, replace the gas
setting label on the appliance with the label for the new gas. The label is supplied in the bag with the
nozzles.
4.1
Adjusting the hob burner minimum for town gas and natural gas
Light the burner and turn it to the minimum setting . Remove the gas
tap knob and adjust the regulator screw beside the tap rod until an even
minimum flame is obtained.
Put the knob back in place and check the stability of the burner flame
(the flame must not go out when the knob is turned quickly from the
maximum to the minimum setting). Repeat the operation on all the gas
taps.
On models equipped with valves, keep the knob pressed down on the minimum setting for a few
seconds to keep the flame alight and prime the safety device.
4.2
Adjusting the hob burner minimum for bottled gas
To adjust the minimum level when using bottled gas, the adjuster screw beside the tap rod must be
turned fully clockwise.
The diameters of the bypasses for each individual burner are stated in point "3.2/3.3 Burner and
Nozzle Data Tables". When the adjustment is complete, re-seal the bypasses with paint or another
similar material.
4.3
Adjusting the oven burner minimum
The oven thermostat has a screw for regulating the minimum setting, accessed by removing the
thermostat knob.
When the type of gas used changes, the minimum setting must be adjusted as follows:
•
Light the oven burner and keep it operating at the highest setting for 10/15 minutes with the door
closed and without the hob. Now turn the knob to the minimum temperature setting, remove the
knob and use a straight-head screwdriver to adjust.
•
When using bottled gas, the adjuster screw must be turned fully clockwise. The diameter of the
by-pass is stated in point “3.2/3.3 Burner and Nozzle Data Tables”.
•
When using town or natural gas, adjust the screw so that when the thermostat knob is turned
from the maximum to the minimum setting, the flame always remains stable and uniform. When
the adjustment is complete, re-seal the screw with paint or equivalents. Close the oven door and
check that the burner remains on at the minimum setting.
