8. The pressure safety device (safety valve
or unit) must not be tampered with and
must be operated regularly to verify that
it is not clogged and to remove any li-
mescale deposits.
9. It is normal that the safety unit drip when
water is being heated. For this reason
the drain outlet must be connected and
always left open to the atmosphere, with
a continuously downward-sloping drain-
age pipe installed in a location which is
not subject to icy conditions.
10. The appliance must be drained and dis-
connected from the mains if it is to be
left inactive in a room subject to frost.
11. Hot water running from taps at temper-
atures above 50°C may immediately
cause serious burns. Children, the disa-
bled and the elderly run a greater risk
in this regard. It is therefore advisable to
use a thermostatic mixing valve connect-
ed to the appliance's water outlet pipe
(which is identified by a red collar).
12. No flammable items should be left in
contact with or in the vicinity of the ap-
pliance.
13. Do not stand under the appliance or
place anything under it that may be dam-
aged by water leaks, for instance.
14. Do not use insecticides, solvents or ag-
gressive detergents to clean the appli-
ance; these may damage the plastic or
coated surfaces.
15. If you detect a smell of burning or smoke
coming from the appliance, shut it off,
turn off the main gas valve, open all win-
dows and call for assistance. Risk of in-
jury due to burning, smoke inhalation or
intoxication.
16. To keep the appliance in good working
order, it must be serviced annually and
have its combustion tested as required
by local legislation. The technician do-
ing these jobs must be qualified and
fill out the maintenance booklet, as re-
quired by law.
