2.2 CONNECTING TO THE FLUE (GAS POWERED OVENS)
The gas appliances are provided with a flue for eliminating the residuals of combustion.
This flue must be connected as illustrated in Figure 2.2 as established by the installation rules.
Forced fumes evacuation type A1: (Fig. 2.2)
The appliance is of the A1 type. It must to be installed in sufficiently ventilated rooms to prevent the possibility
of unacceptable concentrations of substances harmful to health in the room in which the appliance is installed,
made in accordance with national and local laws and regulations in force. Indicatively the flow rate of an air
aspirator connected directly to the external environment is 35 m
3
/h for each kW of gas power installed. The
appliance must be installed in sufficiently ventilated rooms to ensure the air flow necessary for combustion, in
accordance with the national and local laws and regulations in force.

2.3 WATER FEATURES
The water must be suitable to human use with the following characteristics:
Temperature
: included between 15 – 20°C
Total hardness
: included between 4 and 12 °f (French degrees), it is advisable to install a softener upstream
from the appliance that will maintain the hardness level at the mentioned values.
Pressure
: included between 150 and 250 KPa (1,5 – 2,5 bar).
Attention: higher water pressure values result in increased water consumption and can compromise
the correct functioning of some components.
Maximum chloride concentration
(Cl-): less than 150 mg/litre.
Chlorine concentration
(Cl2): less than 0.2 mg/litre.
pH
: more than 7.
Water conductivity
: included between 50 and 2000 µS/cm.
Attention: Water treatment systems that bring to different values to the ones above mentioned au
-
tomatically invalidate the guarantee.
The use of dosing systems designed to prevent the build-up of lime-scale in pipes (i.e. polyphosphate dosing
systems) is also prohibited since it may impair the performance of the appliance.
