8 MAINTENANCE
There is very little maintenance thanks to the correct way the appliances have been made.
However, we do advise having the systems checked by qualified personnel at least twice a
year.
N.B.: the manufacturer declines all responsibility for direct or indirect damage caused by
incorrect installation, bad maintenance, tampering, improper use and failure to comply with
the accident prevention norms regarding the prevention of fire and safety for gas systems
8.1 CONVERSION FOR USE WITH A DIFFERENT TYPE OF GAS – TOP BURNERS
The appliance is tested and set for working with gas according to 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 follows:
•The conversion must be carried out by qualified personnel
•The nozzles for LPG are supplied with the appliance in a nylon bag
•Changing the burner nozzles: fig. 1
remove the rungs (1) and the burner flame separators and replace the nozzles attached
to the bottom of the burner bodies in accordance with the TECHNICAL DATA TABLE
based on the type of gas. (Fig. 3)
•Regulating the minimum flame: fig. 1
remove the cock knobs (8), with a screwdriver turn the cock (6) adjustment screw (7)
until you get the minimum flame required.
•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.
Attention: after each conversion, apply the new calibration by affixing the relative plate,
that you will find in the bag of nozzles, on the appliance’s rating plate
Changing top burner parts
Safety cock (6): remove the rungs (1), disassemble the control panel (12), unscrew the
burner connection pipes (13), unscrew the bridles (14) for fastening to the ramp, unscrew
