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.
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).
• 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 7,3 kW and 3,5 kW for the burner of 11 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.
SUBSTITUTING THE NOZZLE IN THE COUP DE FEU 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.
