MAINTENANCE AND CLEANING
48
Cleaning the drain-trap
− Disconnec t the pipes (A) and (B), take out the clip
(C) and remove the drain-trap.
− Loosen the lower and upper plugs, then take out
the oat.
− Clean the parts of the drain-trap to remove any
solid residue.
9
Do not remove the oat and the relative sealing
gasket, as their job is to prevent the leakage of
burnt gases in the room if there is no condensate.
9
Reposition the previously removed components
carefully. Check the oat sealing gasket and replace
it if necessary. If the oat gasket is replace, make
sure the new one is correctly positioned in its seat
(refer to the section gure).
9
After cleaning, ll the drain-trap with water (see
paragraph “3.1 Preliminary checks”) before starting
up the boiler again.
9
After completing the maintenance work on the
drain-trap, we recommend running the boiler in
condensing mode for a few minutes to check there
are no leaks along the entire condensate evacua-
tion line.
9
If the appliance has been left unused for more than
60 days, the drain-trap in the boiler must be lled.
If the boiler is installed in a place where the am-
bient temperature may remain above 30°C for long
periods, ll the drain-trap after 30 days of non-
use. This operation must be carried out by profes-
sionally qualied personnel.

Ionisation electrode
The detector electrode play an important role in the
boiler ignition phase and maintaining an efcient com-
bustion; in this regard it is necessary to check its in-
tegrity and ensure that it is correctly positioned, strictly
respecting the reference position indicated in the gure.
If necessary replace it. The same rule applies to the ig-
nition electrode.

Do not sandpaper the electrode.

During the annual maintenance, check the state of
wear of the electrodes and replace it if has badly
deteriorated.

The removal and eventual replacement of the elec-
trodes, including the ignition electrode, involves
also the replacement of the sealing gaskets.
Non-return valve
The boiler has a check valve.
