·Standard UNI-CIG 8723, Ministerial circular no. 68 dated 25/11/69 and variations.
·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 DISCHARGE OF FUMES FOR TYPE “B”APPLIANCES
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.

6.5 CHECKING FOR GAS LEAKS
Once installed, check there are no gas leaks on pipe joints 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 checki ng 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 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.
