Regulation of burners

Regulation of the "MINIMUM" on the burners

To regulate the minimum on the burners carry out the following procedure indicated below:

1)Turn on the burner and put the knob onto position MINIMUM ( small flame ).

2)Remove the knob ( Fig. 7) of the tap which is set for standard pressure. The knob is found on the bar of the tap itself.

3)Beside the tap bar on the work top, insert a small slotted screwdriver into the hole on the vale rod (Fig. 7) and turn the choke screw to the right or left until the flame of the burner is regulated in the most suitable way to MINIMUM.

4)Make sure that that the flame does not go out when changing the position quickly from MAXIMUM to the MINIMUM position.

ATTENTION: The regulation described above can be carried out only with burners using natural gas, while with burners using propane gas the screw must be fully screwed in, in a clockwise direction.

Adaptation of the pressure regulator for use with different type of gas

The pressure regulator supplied with the appliance is a convertible type pressure regulator for use with Natural Gas at a nominal outlet pressure of 4” w.c. or LP gas at a nominal outlet pressure of 11” w.c. and it is pre-arranged from the factory to operate with one of these gas/pressure as indicated in the pre-arranging labels affixed on the appliance, package and Instruction booklet.

To convert the regulator for use with the other gas different from which one it is pre-arranged it is enough perform the following operations:

1)Unscrew by hand the upper metal stopper of the regulator (Fig. 5A).

2)Unscrew by hand the white plastic piece screwed under the above mentioned metal stopper, afterward screw it again in opposite way under the metal stopper (for gas reference see the written “LP” and “NAT” with relative indicating arrows on the white piece).

3)Screw again by hand the metal stopper in the original position on the regulator.

Operating in this way the gas regulator is converted for use with the other gas/pressure.

Service & maintenance instructions

Service and maintenance only to be carried out by an authorised person

To replace parts such as burners, valves and electric components, the hotplate must be removed from the bench top by releasing the attachment hooks, loosening the attachment screws of each burner, unscrewing the hotplate attachments nuts which are visible at the bottom of the surface, removing the hotplate top and finally replacing the defective parts.

Note: if the valves must be replaced, first disassemble the ignitions switches wires.

It is recommended to replace the valve gaskets each time the valve is replaced, thus ensuring a perfect seal between the body and the gas train.

WARNING: Disconnect power before servicing unit.

For the location of the wall receptable for the connection of the three-pin earthed plug of the appliance, see indications given in Fig. 1- 2

WARNING: After first installation of the appliance or after any service intervention concerning main gas parts of the appliance, make the leak test using water with soap on the gas connections in order to verify the correct installation. Do not use fire for gas leak testing.
