gate valve. This valve should be closed when the appliance is not in operation.
1.5 COMBUSTION PRODUCTS........................................................................
The appliances must be installed in places appropriate for the removal of fumes
according to installation specifications. Our appliances are considered (see
technical data table) as appliances to Gas Type A:
Such appliances must send fume into appropriate aspirants connected to safe
and effective pipes that direct them outdoors.
Attention
The appliances must always be installed below 200 mm on three sides an
aspirant, which directs fume outdoors.
The appliances whose total thermal power is superior to 14Kw must be
obligatorily installed under aspirant, intercepting and piloting the system of
feeding of the gas of the appliance,
Particularly, the supply circuit electric valve at the top of the appliance must be
switched - off.
Make sure that there are not dispersions in the aspirant system. The limits of
course are established by the norm of installation UNI-CIG 8723 point 4.3
