RULES FOR CONVERTING AND INSTALLING OTHER TYPES OF GAS
Our appliances are tested and regulated for liquid gas.
The conversion or adaptation to another type of gas must be carried out by a specialized technician. The nozzles
for the various types of gas are in a packet supplied with the appliance and are marked in hundredths of mm (see
the technical data table).
CHANGING THE OPEN RING NOZZLES
Main nozzles
Take the rungs off, remove the burners and trays, with a size 12 spanner substitute the nozzles with the appropriate ones, regulate
the primary air (h) (see the “burner” technical data table) unscrewing the securing screw. Once regulated, tighten the screw, adjust
the minimum flame by turning the screw to the right or left until the thermal power reaches 1,15 kW for the 3,5 kW burner, 1,55
for the 5,5 kW burner and 2,5 kW for the 7 kW burner.
Warning:
If liquid gas is being used the minimum adjustment screw must be locked right down.
CHECKING FUNCTIONING
The appliance contains the instructions necessary for use.
Check the appliances for gas leaks.
Check the lighting and flame of the main burner.
We urge the user to follow the instructions when using the appliance.
MAINTENANCE
With prolonged use of the appliance, it is essential to carry out regular maintenance for the safe functioning of the
appliance; we therefore recommend drawing up a contract for after sales service. Maintenance must be done only
by specialized personnel, observing the norms in force and our indications.
SPARE PARTS
Open rings:
The cocks can be changed by removing the front panel; to change the thermocouples and burners you have to
remove the rungs and trays.
