INSTALLATION
Translation of the original instructions

- "A" type devices (see data plate)
"A" type appliances must discharge combustion products into appropriate hoods, or similar devices,
connected to an efficient fume stack or directly to the outside. (Natural evacuation) Fig. 1
If this is not possible, using an air suction device connected directly to the outside is permitted (Forced
Evacuation) Fig.2, having a flow capacity not lower than the value defined in point 4.3 of the UNI-CIG 8723
standard.
- In the case of forced evacuation
The gas supply to the appliance must be directly servo-controlled by the system and must stop if the flow
rate drops below the values indicated in point 4.3 of the UNI-CIG 8723 standard. Resetting the gas supply to
the appliance must be possible only by hand.

- "B11" type devices (See data plate)
Natural evacuation (fig.3)
Connection to an efficient natural draft fume stack by means of a windproof connection, with discharge of
combustion products directly to the outside
Forced evacuation (fig.4)
The gas supply to the appliance must be directly servo-controlled by the forced evacuation system and must
stop if the flow rate drops below the values indicated in point 4.3 of the UNI-CIG 8723 standard. Resetting
the gas supply to the appliance must be possible only by hand. If the installation is under a hood, the
terminal part of the appliance's exhaust pipe must be at least 1.8 meters from the appliance's support
surface (ground). The outlet section of the exhaust pipes for combustion products must be placed within the
perimeter in relation to the hood itself.
