The pressure on the pressure gauge has
gone down
It is necessary to top up the appliance with
water again, so as to raise the pressure to
an adequate level as described in the sec-
tion "Refilling procedure" to page 11 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.
Water should occasionally leak from the
boiler
Shut off the valves positioned under the
boiler to page 14 and call an Authorised
Service Centre Engineer.
In this case or in case of prob-
lems other than those men-
tioned here, switch off the boil-
er, as described in section
"Extinguishing" to page 14 and
call a competent and responsi-
ble Service Engineer.
