Adaptation to different types of gas

A. Injectors replacement

• Remove the pan supports.

• Remove the burner's caps and

crowns.

• With a socket spanner 7 unscrew

and remove the injectors (Fig. 1), and

replace them with the ones required

for the type of gas in use (see table

Gas burners).

• Reassemble the parts, following the

same procedure backwards.

• Replace the rating label (placed near

the gas supply pipe) with the relevant

one for the new type of gas supply.

You can find this label in the package

of the injectors supplied with the

appliance.

Should the feeding gas pressure be

different or variable compared with the

required pressure, an appropriate

pressure adjuster must be fitted on the

gas supply pipe, in compliance with the

rules in force.

B. Adjustment of minimum

level

To adjust the minimum level of the

burners, proceed as follows:

• Light the burner.

• Turn the knob on the minimum

position.

• Remove the knob.

• With a thin screwdriver, adjust the

by-pass screw (see Fig. 2). If

changing from natural gas 20/13

mbar to liquid gas, completely

tighten the adjustment screw in. If

changing from liquid gas to natural

gas 20 mbar, undo the by-pass

screw about 1/4 of a turn. If

changing from natural gas 20 mbar

to natural gas 13 mbar undo the by-

pass screw about 1/4 of a turn. If

changing from liquid gas to natural

gas 13 mbar, undo the by-pass

screw about 3/4 of a turn.

• Finally check the flame does not go

out when quickly turning the knob

from the maximum position to the

minimum position.

This procedure can easily be carried

out, anyhow the hob has been

positioned or built in the working top.
