staller checks that:
– the connecting flue pipe is suitable for the combustion tem-
perature of the appliance, calculated and manufactured in
compliance with Standards, that it is as straight as possible,
air tight, isolated, with no obstructions or restriction and that
it has appropriate condensate collection and evacuation sys-
tems
– the electrical system is constructed by professionally quali-
fied personnel, respecting the specific regulations
– the fuel supply line is made in conformity to the relevant
standards
– the expansion vessel ensures total absorption of the fluid di-
lation in the system
– the pump flow-head performance is sufficient for the system
characteristics
– the system is clean, free of any sludge, deposits, de aerated
and air tight. For system cleaning, please refer to the relevant
paragraph.

Cleaning the system

Fig. 29
Before installing the appliance on a newly constructed system
or replacing a heat generator on an existing system, it is impor-
tant that the system is thoroughly cleaned to remove any sludge,
slag, dirt, residues, etc.
Before removing an old heat generator from an existing system,
it is recommended that the user:
– puts a descaling additive into the water system
– allows the system to work with the generator active for a few
days
– drains the dirty water from the system and flushes the system
with clean water once or more than once.
If the old generator has already been removed or is not availa-
ble, replace it with a pump to circulate water in the system and
then proceed as described above.
Once cleaning operations have been carried out and before
installing the new appliance, it is recommended that a fluid is
added to the water system to protect it from corrosion and de-
posits.
m
CAUTION
– For further information on the type of additive and
usage, please contact the appliance manufacturer.
6.7

Water system treatment

When filling and restoring the system it is good practice to use
water with:
– appearance: clear
– pH: 6,5 ÷ 8,5
– hardness: < 19.96°F
– the maximum allowed content of chlorides is 250 mg/l
– it is recommended that the total quantity of water to use, in-
cluding top-ups, with a total hardness of 20°F DOES NOT ex-
ceed 20 litres/kW
