Warning! The following instructions about

installation, maintenance and ventilation

must be carried out by qualified personnel in

compliance with the regulation in force (UNI-

CIG 7129 - 7131). Make sure that the kitchen

is well ventilated: keep natural ventilation holes

open (at least 100 cm²) or install a mechanical

extractor hood.

Gas Connection

Choose fixed connections or use a flexible pipe

in stainless steel in compliance with the regula-

tion in force. If you use flexible metallic pipes,

be careful they do not come in touch with mo-

bile parts or they are not squeezed. Also be

careful when the hob is put together with an

oven.

Important! Make sure that the gas supply

pressure of the appliance obeys the

recommended values.

If the supplied pressure has not the specified

value, it is necessary to assemble a proper

pressure regulator in compliance with the

standard UNI EN 88. For Liquid Gas (LPG) the

use of pressure regulator is allowed only if they

are in compliance with UNI EN 12864. The ad-

justable connection is fixed to the comprehen-

sive ramp by means of a threaded nut G 1/2".

Screw the parts without force, adjust the con-

nection in the necessary direction and tighten

everything.

Rigid connection:

Carry out connection by using metal rigid pipes

(copper with mechanical end) (UNI-CIG 7129).

Flexible connection:

Use a flexible pipe in stainless steel (UNI-CIG

9891) with a maximum length 2 m.

Important! When installation is complete,

make sure that the seal of each pipe fitting is

correct. Use a soapy solution, not a flame!

Injectors replacement

1. Remove the pan supports.

2. Remove the caps and crowns of the burn-

er.

3. With a socket spanner 7 remove the injec-

tors and replace them with the ones which

are necessary for the type of gas you use

(see table in "Technical Information" chap-

ter).

4. Assemble the parts, follow the same pro-

cedure backwards.

5. Replace the rating plate (it is near the gas

supply pipe) with the one for the new type

of gas supply. You can find this plate in the

package supplied with the appliance.

If the supply gas pressure is changeable or dif-

ferent from the necessary pressure, you must fit

an applicable pressure adjuster on the gas sup-

ply pipe.

Adjustment of minimum level

To adjust the minimum level of the burners:

1. Light the burner.

2. Turn the knob on the minimum position.

3. Remove the knob.

4. With a thin screwdriver, adjust the by-pass

screw position.

to liquid gas, fully tighten the adjustment

screw in.
