Boilers must be always equipped with original accessories only.
ITALTHERM Srl is not responsible for damages caused by the incorrect, wrong or unreasonable
use of not original materials.
The burner doesn’t turn on
f
if the room thermostat (or programmable room thermostat, or similar) is installed, check that it is
really requiring the room heating;
f
check that the electrical power supply is present and that the Summer/Winter knob isn't posi
-
tioned on
(stand-by) but on Summer
or Winter . The
GREEN
light should be
steadily ON
(see details in the paragraph "The front control panel" on page 7);
f
if the
RED
locking light was on or blinking, or if you notice an anomalous behaviour of the light indi-
cators, see the paragraph "Alarms - boiler block" on page 39;
f
check on the gauge that the boiler pressure is correct (1÷1.5 Bar
in a cold state
) or at least
not below
0.5 Bar;
f
let the technician to look up the notes in the paragraph "Electrical diagram" on page 49.
Shortage of domestic hot water production
f
check that knob
is not set on a too low value or to the
“service”
position
f
call a qualified technician to check gas valve regulation;
f
call a qualified technician to check, and eventually clean, the coil of the DHW storage.
Remark: where the water hardness value is too high, it is suggested the installation of a soften-
ing device, in order to prevent the limestone precipitation; this operation avoids a frequent
cleaning of the coil of the DHW storage.
Boiler inactivity
The effects of the periods of inactivity can be relevant in particular situations such as in flats used only
for some months per year, most of all in cold places.
The user will have to decide to put the boiler in the
SAFETY SHUT OFF state
disconnecting all the sup-
plies, or to leave it in stand-by and use the Anti Frost Function
. When there is the possibility of freezing
it is convenient to chose between the advantages and the disadvantages of the SAFETY SHUT OFF and
of the Stand By/Anti Freezing Way.
Safety shut off
f
Turn off the general switch on the Electrical Supply Line of the Boiler;
f
Close the Gas Tap;
When it is expected that the temperature is going to decrease under 0°C, call a technician to do
the following:
•
Fill the system, included the primary circuit of the storage unit and the relevant coil, with an
anti-freezing solution (unless the system was already filled with said solution) otherwise it must
be completely emptied. Notice that if it had been necessary to restore the pressure (because of
possible loss) in an heating system already filled with an Anti freezing solution, the concentration
of the solution could have decreased and it could not guarantee the Anti freezing Protection.
• let the condense collector syphon be emptied unscrewing its inferior cap.
