Installation, Use and Maintenance
4.2.2.1.
Single boiler installation case
!
ATTENTION:
The combustion product extraction duct must be dimensioned by
using the parameters set out in the table in chapter 3.2.
Depending on the actual con
fi
guration of the duct, a calculation is
required to check that the pressures at the boiler outlet do not exceed
the maximum allowable values in this table.
Values corresponding to the 50/30°C regime are to be used for this
calculation.
4.2.2.2.
Cascade installation case
!
ATTENTION:
The combustion product extraction duct must be dimensioned by
using the parameters set out in the table in chapter 3.2.
Depending on the actual con
fi
guration of the duct, a calculation is
required to check that the pressures at the boiler outlet do not exceed
the maximum allowable values in this table.
Values corresponding to the 50/30°C regime are to be used for this
calculation.
The installation must be done so that if one of the boilers is stopped or
operating at minimum, the others do not discharge into it. Depending on the
installation con
fi
guration, it may be necessary to install a valve at the boiler
outlet.
For this type of connection, the manufacturer offers exhaust connection
accessories with duct diameter A = 160 mm for the 40 and 60 kW models
and A = 200 mm for the 80 and 100 kW models. These accessories contain
a valve for each boiler.
If boilers of different power ratings are being connected, the most powerful
models should be closest to the chimney.
NOTE: The manufacturer's accessories do not allow 40/60 kW models
to be combined with 80/100 kW models.
