6. Useful Advice Cont.
If water comes out of the pressure relief valve pipe 3 in Fig. 6.3:
• Check on the temperature and
pressure gauge (figure 5.1 on page
12) that the pressure in the central
heating circuit is not close to 3 bars
(43.5 psi). 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 heating
system.
If water should occasionally leak from the boiler:
• Close the cocks connected to the inlet gas pipe and to the supply cold water inlet pipe
under the boiler and call an Authorised Service Person.
In case of problems other than those mentioned here, switch off the boiler, as
described in Section 5.5 on page 14 and call a competent and responsible service
person.
