RULES FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS

Our appliances are tested and regulated with liquid gas (see data plate).
The conversion or adaptation to another type of gas must be carried out by a specialised technician. The nozzles for the
various types of gas are supplied in a packet and are marked in hundredths of mm (see "burners" technical data table).

CHANGING THE OPEN RING NOZZLES

Main nozzles (Fig. C):

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.
Caution: If liquid gas is being used the minimum adjustment screw must be locked right down.

Pilot nozzles (Fig. D):

Take the rungs off, remove the burners and trays, with a size 8 spanner loosen the nozzle holder unit, with a size 11
spanner unscrew the nozzle holder all the way, with a slotted screwdriver unscrew the pilot nozzle and replace it with
the appropriate one and tighten right down.
