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 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 1.5
kW for the 45 kW burner, 1.8 for the 7 kW burner and 2.3 kW for the 10 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.
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 ALL PLATE BURNER
Remove the panel and with a suitable spanner substitute the nozzle with another, suitable one.
Adjust the minimum flame by turning the by-pass screw either to the right or to the left until heat output reaches 4 kW.
The primary air of the all plate burner does not need adjusting.
Attention: If liquid gas is used, the minimum flame adjustment screw must be screwed right down.
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 for the burner of 8,5 kW and 3,5 kW for the burner of 13 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.
•
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.
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 specialised personnel, observing the norms in force and our indications.
All plate:
It is possible to substitute the spark plug cock, thermocouple and burner after having removed the front panel.
Open rings:
The cocks can be changed by removing the front panel; to change the thermocouples and burners you have to remove
