INSTALLATION
6.1
Warnings
The use of gas appliances is sub-
ject to statutory control; it is es-
sential to observe the current
regulations and laws in force (see
also chapter 5).
The appliance must discharge
combustion
outside or into a suitable exhaust
duct designed for this purpose.
Combustion products must be
discharged using original flue kits
only, since they are integral parts
of the boiler.
The appliance is not suitable for
receiving
from the combustion products
evacuation system.
Combustion air must avoid con-
tents of chlorine, ammonia, or al-
kali agents. Installation of a boiler
near a swimming pool, a washing
machine, or a laundry does ex-
pose combustion air to these ag-
gressive contents.
Before installing the boiler on an existing c.h.
system, flush it out thoroughly before fitting
the boiler.
This procedure is to remove the presence of
any residues or impurities that could compro-
mise good functioning of the boiler.
After washing it is necessary to treat the plant.
The conventional warranty does not cover any
problems deriving from failure to comply with
such provisions.
For Propane, the appliance must also conform
with the requirements of the distributors and
comply with current Regulations and laws in
force.

• a fused spur isolation switch, must be in-
stalled near to the boiler that allows com-
plete disconnection in overvoltage III cat-
egory conditions.
Refer to section "Electric connection" to page
43 in this chapter for the electrical connec-
tions.
In no circumstances will the manufacturer

structions contained in this manual have
not been complied with.
