INSTRUCTIONS FOR DISCHARGING GAS EMISSIONS
Type “A” Appliances (See Data plate)
Type “A” appliances must discharge the products of combustion into extractor hoods or similar devices connected to
and efficient chimney, or directly outside. (Natural Discharge) Fig.1.
If there is no hood, as an alternative, an air extractor connected directly to the outside is acceptable, (Forced
Discharge) Fig.2, but its capacity must not be inferior to what is established in item 4.3 of the UNI-CIG norm 8723.
In the event of forced discharge
The gas supply to the appliance, must be directly interlocked to the system and must cut off automatically if its capacity
drops below the values prescribed by item 4.3 of the UNI-CIG norm 8723.
Supplying the appliance with gas again must only be possible manually.
