Installation Instructions
Condensation drain
The boiler, during the combustion process, produces
condensation that, through pipe “A”, flows into the
trap.
The condensation that forms inside the boiler flows
into a suitable drain via pipe “B”.
Danger!
Before commissioning the appliance:
- check that the trap is assembled
properly, make sure that the inner
plastic tube passes under the pump
(not near the plate heat exchanger).
- Check that the condensation is
drained properly, if the appliance
is used with the condensate drain
siphon, without the protection device
C (sphere) inserted, there is danger
of intoxication following out exhaust
gases.

the drainage system
3.7 - CONNECTION
Danger!
The gas connection must be carried out
only by a qualified installer who must re -
spect and apply that foreseen by relevant
laws in force in the local prescriptions of
the supply company. Incorrect installation
can cause damage to persons, animals
and objects for which the manufacturer
cannot be held responsible.
If you smell gas:
a) Do not operate electric switches,
the telephone or any other object that
may cause sparks;
b) Immediately open doors and
windows to create air current
to purify the room;
c) Shut the gas cocks.
The mains pressure must be within 1 and 3
bar (in the event of greater pressure install
a pressure reducer).
