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).
Main nozzles (Fig. C):
Take the panel off, 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 1.55 kW for the 5.5 kW burner,
and 2.5 kW for the 8.5 kW burner.
Caution: If liquid gas is being used the minimum adjustment screw must be locked right down.
Pilot nozzles (Fig. D):
Take the grids off, 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.
Put everything back in place and regulate the air by means of the adjusting bush until the pilot flame stops sputtering
and becomes an intense blue colour.
SUBSTITUTING THE NOZZLE IN THE OVEN BURNER
To substitute the oven burner, proceed as follows:
• Remove the oven bottom (floor);
• Unscrew the fixing screws from the burner nozzle protection.
• Substitute the nozzle, using a suitable spanner (see "burners" technical data table on page 7).
• Regulate the air regulation bush to the corresponding value in the "technical data" table by unscrewing the fixing
screw with relative jam nut, regulate minimum output by turning the screw to the right or to the left until the
thermal power reaches 2,2 kW, this procedure is only possible after having let the oven burner work at maximum
output for about 20 minutes (knob in pos. 300).
• After this procedure, put back the burner nozzle protection.
• Substitute the pilot nozzle, using a suitable spanner.
After regulating, check lighting, at both maximum and minimum output. Make sure that, when changing rapidly
from minimum to maximum output, the flame does not present any problems and that it doesn't go out, when
closing or opening the oven door quickly.
Warning: For functioning with liquid gas, screw down the regulating screw completely.
