MAINTENANCE
To guarantee functioning and efficiency of
the appliance, in respect of the legal provi-
sions in force, it must be regularly checked;
the frequency of the checks depends on
the type of appliance and the installation
and usage conditions. In any case, it should
be inspected at least once a year by a quali-
fied technician.
During maintenance operations, it is
important to verify that the drip-plate
with drain trap contains water (this
check is particularly important if the
generator has not been used for exten-
100
ded periods of time).
If necessary, the drip plate can be filled
using the tap provided (fig. 20).
Instead, to clean the exchanger and the
burner, do in the following way (fig. 20):
– Cut power from the boiler.
– Empty the condensation-collecting tray.
– Remove the sleeve.
– Spray the water jet inside of the burner
and the exchanger in order to remove
dust and combustion residue.
DO NOT USE CHEMICAL AGENTS OR
STEEL BUSHES.
– Remove the condensation-collecting tray.
Clean it and put it back tightening the
fixing nuts with a torque wrench.
– Having re-assembled the tray, check its
sealing with a leak detector.
