4 USE AND MAINTENANCE
ATTENTION: Before performing any work on the boiler, make sure that the same and its components have
cooled in order to prevent the risk of burns due to high temperatures.

4.5 MAINTENANCE
(fig. 20)
To. guarantee. functioning. and. efficiency.
of. the. appliance,. in. respect. of. the. legal.
provisions. 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. qualified. techni-
cian.
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-
ded periods of time).
If necessary, the drip plate can be filled
using the tap provided (fig. 20).
