6.3 DISCHARGE OF FUMES FOR TYPE “A” APPLIANCES<br />

The appliances must be installed on premises that are suitable for the discharge of the<br />

products of combustion and must be in compliance with what is established by the<br />

installation rules. Our appliances are considered type “A” gas appliances (see the<br />

Technical Data Tables) and are not for connecting to a natural discharge duct for the<br />

products of combustion.<br />

These appliances must discharge through specific extractors, or similar devices,<br />

connected to a properly working flue or discharged directly outside.<br />

If this is not possible, an air suction device can be used connected directly to the outside,<br />

with a capacity that must be no less than that required plus the quantity of fresh air that is<br />

necessary for the well-being of the workers.<br />

6.4 DISCHARGE OF FUMES FOR TYPE “B” APPLIANCES<br />

The appliances must be installed on premises that are suitable for the discharge of the<br />

products of combustion and must be in compliance with what is established by the<br />

installation rules.<br />

The appliances must be installed on premises that are suitable for the discharge of the<br />

products of combustion and must be in compliance with what is established by the<br />

installation rules.<br />

Our appliances are considered (see the Technical Data Table) type B gas appliances, and<br />

are for connecting to a natural discharge duct for the products of combustion like, for<br />

instance, connected to an efficient natural draught flue or discharged directly outside or<br />

they can be interlocked with a forced discharge system, like a hood fitted with a<br />

mechanical extractor.<br />

If the products of combustion are discharged by means of a forced system:<br />

• the supply of gas to the appliance must be interlocked directly to the forced discharge<br />

system and must stop if the capacity of the system drops below the values prescribed. It<br />

must be only be possible to start the gas supply to the appliance by hand;<br />

• If the appliance is installed under a hood, the end of the appliance’s discharge pipe<br />

must be at least 1.8 m from the surface on which the appliance is standing, the<br />

discharge pipe opening’s cross section must be inside the base perimeter of the hood.<br />

1,8 m<br />
