Protection against freezing
If the boiler is to be out of use for any long periods
during severe weather conditions, it is recom-
mended that the whole system, including the
boiler, be drained to avoid the risk of freezing.
If in doubt, consult your servicing company.
Draining and filling
Caution :
the boiler is installed as part of a sealed
system which must only be drained and filled by a
competent person.

If there is persistent loss of system pressure,
indicated by the pressure gauge, you must con-
tact the installer or servicing company.

fitted to this boiler.
The valve

time, switch the boiler off and isolate it from the
electrical supply. Contact your installation/servic-
ing company.
