General information
1.7 WATER TREATMENT
Treating the feed water allows you to prevent prob-
lems and maintain the functionality and eciency of
the generator over time.
e ideal pH value of the water in the central heating
system must be:
VALUE MIN. MAX.
PH 6.5 8
HARDNESS (°fr) 9 15
To minimise corrosion, it is essential to use a corrosion
inhibitor. In order for it to work eciently, the metal
surfaces must be clean.
ATTENTION!
Any damage caused to the boiler, due to the formation
of build-up or corrosive water, will not be covered by
the warranty.
ATTENTION!
e models only equipped with central heating are
NOT suitable for hot water production for human
consumption (M.D. 174/2004).
1.8 BOILER FROST PROTECTION
Activated by default
is protection only cuts in when the electric and gas supply are present.
If the electric or gas supply are disconnected and 11 (SM) detects a
temperature of between 2 and 5°C when the supply is restored, the
appliance responds as indicated in the table below, in pos.2.
Antifreeze products with an inhibitor for central
heating systems (specic for multimetal) can be used
to ensure ecient protection of the central heating
against freezing.
Do not use antifreeze products for car engines since
these can damage the water gaskets.

3.1 GENERAL RECOMMENDATIONS
ATTENTION!
is boiler must only be employed for its explicitly
intended use. Any other use must be considered
improper and therefore dangerous.
is boiler is used to heat water to below boiling
temperature in atmospheric pressure.
ATTENTION!
These appliances are designed exclusively for
installation inside suitable technical compartments.
Before connecting the boiler, have professionally
authorised company:
a) Accurately washing all of the pipes in the system
to remove any residues or sediments could stop
the boiler form running eciently, even in terms
of health and hygiene.
b) Making sure the boiler is set up to operate with the
available type of fuel. e type of fuel is stated on the

e boiler room is equipped with a pipe for the evacuation of the
condensation produced by the boiler.
- e electrical system is built in accordance with specic regulations
and by professionally authorised company.
- e ow rate, head and direction of ow of the circulation pumps is
appropriate.
- e fuel feed line and any existing tanks are set up in accordance with
regulations in force.
- e expansion vessels ensure complete absorption of the dilation of
the uid contained in the system.
- Slurry and build-up have been cleaned out of the system.
If it is possible to schedule the replacement, the system must be washed
preventively with alkaline dispersants.
Washing must be carried out four weeks prior to replacement, with a
system operating between 35°C - 40°C.
Attention! If the new boiler has been replaced in an old system without
having preventively washed it as described above, do not wash the sy-
stem, as any residues of the product in the circuit may ll the generator
with residues aer replacement.
It is advisable to contact a company specialised in water treatment.
