ter again, so as to raise the pressure to an ad-
equate level as described in the section "Re-
filling procedure" on page 12 of this manual.
If topping up with water has to be done very
frequently, have the system checked for leaks.
Water comes out of the pressure relief
valve
Check on the pressure gauge that the pres-
sure in the central heating circuit is not close
to 3 bars. In this case, temperature rise in the
circuit can cause the pressure relief valve to
open. So that this does not happen and to
decrease the pressure to a normal value, it
is advisable to vent some of the water in the
appliance through the bleed valves present in
the radiators.
If before water should occasionally leak
from the boiler
Shut off the valves positioned under the boiler
to page 15 and call an Authorised Service
Centre Engineer.
In this case or in case of problems
other than those mentioned here,
switch off the boiler, as described
in section "Switching off" on page
15 and call a competent and re-
sponsible Service Engineer.
