To identify the burners on your hob, refer to the drawings in point “5.8 Arrangement of burners on hob “

If after air setting the flame appears as shown in the diagram:

the following adjustments must be made:

A: the flame is noisy and unstable and comes away from the burner; the primary air

intake is open too far.

B: The flame is cloudy and dull or has yellow dots and wraps round the burner; the

primary air intake is closed too far.

C: The flame is blue, clear and stable and neither comes away from or wraps round

the burner; the air is set correctly.

5.5 Reassembling the hob

Follow the instructions given in paragraph “5.1 Removing the hob ”, but in the reverse

order.

When replacing the burner rings, remember that they have to be tightened completely

by means of the wrench supplied, otherwise the flame interruption zones on the flame

caps will not be aligned with the grid spokes.

When positioning the grids, make sure that the pins are aligned

with their seats in the surface, then press them in with the palm

of your hand until they lock in place.

5.6 Regulation of minimum for natural gas

Replace the components on the burner and slide the

knobs on the gas tap pins.

Light the burner and set it at minimum position

Remove the knob and turn the regulation screw inside

or next to the gas tap pin (depending on the model)

until you get a suitable minimum flame.

Replace the knob and check flame stability by rapidly

turning the knob from maximum to minimum. The

flame should not go out.
