1.5 OMBUSTION PRODU TS........................................................................
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
‘'Removal of combustion products '

2. OPERATION
The appliance is put in operation to the nominal power with the suitable
nozzles (you see chart fig.2). The pressure of feeding must correspond to how
much suitable in the target gives.
2.1 ONTROL OF PRESSURE......................................................................…
To measure the pressure of feeding is enough to prepare of a manometer
to liquid with subdivision least 0.1 mbar (for instance a manometer to U) and
progress in the following way:
• Open the frontal panel in way to enter to the ramp of feeding.
• Unscrew the screw of closing of the taking of pressure
• Connect the manometer and to measure the pressure.
• Remove the manometer, re-screw the screw, and verify that there are not
leaks.
2.2 REGULATION FOR THE OPERATION WITH DIFFERENT GAS.............
