6 INSTRUCTIONS FOR THE QUALIFIED INSTALLER
6.1 APPLIANCE INSTALLATION
•Take the unit out of the packaging. Check that it is in good condition. If in doubt, do not use it
and contact professionally qualified personnel.
Always place the unit under an aspiration hood. After installation, it will need to be levelled by
using the feet.
•Always use rigid galvanised steel or copper pipes for connecting the appliance.
All the seals on the joining threads must be made using materials that are certified for use with
gas.
•If the appliance is wall mounted, in contact with flammable material, place a layer of heat-
resistant insulating material between the appliance and the wall or leave a space of 200 mm
between the appliance and the wall.
•The appliance gas system and the characteristics of the room in which the appliance is
installed must comply with current laws.
•Before connecting the unit, you must check what kind of gas it is set up to use, and whether the
gas which is available to power it is suitable. If the available gas is not suitable for the
appliance, proceed as described in the paragraph "Changeover for operation with other types
of gas".
•Always install a cutoff cock between each appliance and the gas pipe.
•Check that aeration in the room is sufficient when the appliance is working, considering that the
necessary quantity of air for combustion is 2 m³/h of air for each kW of installed power.
6.2 LAWS, TECHNICAL REGULATIONS AND GENERAL RULES
•Please follow the restrictions and the standards in force in the country where the equipment will
be installed.
•Accident prevention laws.
6.3 DISCHARGE OF FUMES FOR TYPE “A” APPLIANCES
The appliances must be installed on premises that are suitable for the discharge of the combustion
products and must comply with the installation rules. Our appliances are considered type “A” gas
appliances (see the Technical Data Tables) and are not for connecting to a natural discharge duct
for combustion products.
These appliances must discharge through specific extractors, or similar devices, connected to a
properly working flue or discharged directly outside.
If this is not possible, an air suction device can be used connected directly to the outside, with a
capacity that must be no less than that required, see Table 1, plus the quantity of fresh air that is
necessary for the well-being of the workers.

6.4 CHECKING FOR GAS LEAKS
•Once installed, check there are no gas leaks from the pipe joints by using a soapy water
solution. You will know if there are leaks by the foamy bubbles that form. Never use bare flames
to check for leaks.
•When the appliance is ready to use, check there are no gas leaks, by checking on the gauge, if
used (for a period of 30 minutes), that there is no passage or consumption of gas.
7 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 damages caused by
incorrect installation, bad maintenance, tampering, improper uses and the failure to comply
with the accident prevention norms regarding the prevention of fire and safety for gas
systems.
7.1 CONVERSION FOR USE WITH A DIFFERENT TYPE OF GAS
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 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.
•Changing the burner nozzle (Fig. 1):
remove the grills (1), grill support (2), the lava supporting frame and you will now be
able to see the burner. Open the burner’s air regulating bush completely (3) 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). (Fig. 4).

•Changing the pilot nozzle (19):
remove the panel (12), unscrew the small pilot connecting pipe, change the nozzle,
inserting it and the small pilot connecting pipe in the nozzle holder together.
Check that there are no gas leaks by using a soapy water solution.
•Regulating the minimum flame:
remove the cock knob (8), use a screwdriver to turn the cock (6) adjustment screw (7)
until you get the minimum flame required.
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 screwdriver 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.
7.2 CHANGING SPARE PARTS
Safety cock (6): remove the panel (12), unscrew the nut connecting the cock to the supply
shaft (9) and to the burner supply pipe, unscrew the thermocouple (15) and the pilot pipe
(16) from the cock, change the cock.
Thermocouple (15): remove the panel (12), unscrew the thermocouple (15) from the cock
(6) and from the pilot support (18) and then change it.
Ignition plug (20): remove the panel (12), unscrew the plug connection nut from the pilot
support (18). Remove the plug and change it.
Piezoelectric lighter (19): remove the panel (13), pull the plug connecting cable out (21),
remove the piezoelectric stop nut and change the lighter.
Pilot burner (18): remove the bottom panel (13), unscrew the pilot connecting nut (23), the
thermocouple (15), remove the ignition plug connecting nut, remove the pilot securing
screws and change the pilot. Now put everything back in place.
