4. INSTRUCTIONS FOR THE QUALIFIED INSTALLER

4.1

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.
4.2

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.

DISCHARGE OF FUMES FOR TYPE "A" APPLIANCES

4.3
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.

DISCHARGE OF FUMES FOR TYPE "B" APPLIANCES

4.4
The appliances must be installed on premises that are suitable for the
discharge of combustion products and must comply with the installation
rules.
Our appliances are considered (see the Technical Data Table) type B
gas appliances, and are for connecting to a natural discharge duct for
combustion products such as an efficient natural draught flue or
discharged directly outside or they can be interlocked with a forced
discharge system, such as a hood fitted with a mechanical extractor.
If the combustion products are discharged by means of a forced
system:
- the appliance gas supply must be directly interlocked with the
forced discharge system and must cut off if the system
capacitydrops below the values prescribed. It must be only be
possible to start the gas supply to the appliance by hand;
- if the appliance is installed under a hood, the end of the
appliance's discharge pipe must be at least 1.8 m from the
surface on which the appliance is standing, the discharge pipe
opening's cross section must be inside the base perimeter of the
hood.

4.5

CHECKING FOR GAS LEAKS

Once installed, check that 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 for 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.

5. 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 use and the failure to
comply with the accident prevention norms regarding the
prevention of fire and safety for gas systems.
5.1 CONVERSION FOR USE WITH A DIFFERENT TYPE OF
GAS – TOP BURNERS
The appliance is tested and set for working with natural 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
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.
