7.1.1 Changing top burner parts
-Safety cock (6): remove the grills (1), burners (3), trays (2), panel (12), unscrew the
connecting pipes (13) and fittings (14) from the gas shaft, unscrew the thermocouple
(15) and change the cock.
-Thermocouple (15): unscrew the cock fitting (6), unscrew the nuts holding the
thermocouple supporting square (16) in place and change the thermocouple.
-Ignition plug (17): unthread the ignition plug (18) connection cable, remove the restraint
spring (2), remove the ignition plug.
-Piezoelectric lighter (19): remove the panel (12), pull the plug connecting cable out
(18), remove the piezoelectric stop nut and change the li ghter.
7.2 CONVERSION FOR USE WITH A DIFFERENT TYPE OF GAS - ALLPLATE
The appliance is tested and set for working with natural gas (see the characteristics table
affixed in proximity to the appliance’s gas inlet).
In order for it to function with a different type of gas, proceed as foll ows:
1. The conversion must be carried out by qualified personnel
2. The set of nozzles for changeover to another type of gas, different from the type for
which the unit was set up, is normally contained in a nylon bag with relative additional
labels that show all the types of gas.
If the set is not provided, it must be requested from the dealer/importer, first
ascertaining that the unit can in fact work with other types of gas.
Once changeover and necessary adjustments are complete, the label for the
corresponding gas must be place in the appropriate place on the characteristics tag,
cutting out the correct one.
3. Changing the burner nozzle (Fig. 8):
remove the panel (12). Open the burner’s air regulating bush completely (24) and
change the nozzle (27). Put everything back in place; place the burner air regulating
bush (24) at the distance specified ("A") in the Technical Data table according to the
type of gas (Fig. 10).
4. Changing the pilot nozzle (23):
remove the panel (12), unscrew the small pilot connecting pipe (16), change the
nozzle, inserting it and the small pilot connecting pipe in the nozzle holder together.
Check there are no gas leaks by using a soapy water solution.
5. Regulating the minimum flame:
remove the cock knob (8) , turn the cock (6) adjustment screw (7) with a screwdriver
until you get the minimum flame required.
5.2 Adjustment of minimum (Fig.2): (machines set up to use LPG and changed over to
natural gas)
Remove the knob (8) from the cock and use a scr ewdriver on the adjustment screw (7)
to tighten it all the way down.
Supply pressure:
it must be that specified on the appliance’s data plate and in the instruction handbook
(see the Technical Data table).
Check the supply pressure by inserting a rubber pipe, with a water gauge or similar, in
the pressure tap (10) welded on the gas shaft (9) removing the screw (11). After it has
been checked, tighten the screw.
If the supply pressure is different to that specified, find the cause and correct it.
