Important! Make sure that the gas supply

Liquid gas

Use the rubber pipe holder for liquid gas. Al-

ways engage the gasket. Then continue with

the gas connection.

The flexible pipe is prepared for apply 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 make

sure its condition.

The control of preservation of the flexible pipe

consists in checking that:

– it does not show cracks, cuts, marks of

burnings 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

supply pipe.

1. Light the burner.

2. Turn the knob on the minimum position.
