Flexible nonmetal pipes connection:

If it is possible to easily control the connection

in its full area, you can use a flexible pipe. Tight-

ly attach the flexible pipe by clamps.

Liquid gas: use the rubber pipe holder. Always

engage the gasket. Then continue with the gas

connection. The flexible pipe is prepared for ap-

ply when:

– it can not get hot more than room tempera-

ture, higher than 30°C;

– it is no longer than 1500 mm;

– it shows no throttles;

– it is not subject to traction or torsion;

– it does not get in touch with cutting edges or

corners;

– it can be easily examined in order to check

its condition.

The control of preservation of the flexible pipe

consists in checking that:

– it does not show cracks, cuts, marks of burn-

ings on the two ends and on its full length;

– the material is not hardened, but shows its

correct elasticity;

– the fastening clamps are not rusted;

– expired term is not due.

If one or more defects are visible, do not repair

the pipe, but replace it.

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.

A) The by-pass screw

• If you change from natural gas G20 (2H) 25

mbar to liquid gas, fully tighten the by-pass

screw in.

• If you change from liquid gas to natural gas

G20 (2H) 25 mbar, undo the by-pass screw

approximately between 1/4 and 1/2 of a turn

for Rapid burner and approximately 1/4 of a

turn for Semi-Rapid and Auxiliary burner.

• If you change from natural gas G25.1 (2HS)

25 mbar to liquid gas, fully tighten the by-

pass screw in.
