Like all condensing boilers
it will produce a plume of
condensation from the flue
terminal in cool weather.
This is due to the high
efficiency and hence low flue
gas temperature of the boiler.
It is normal and not a fault
indication.
If any fault persists, and your appliance still
does not work, leave it switched off and
contact your competent person.
9.1 Electrical Supply Failure
The boiler will not work without an
electrical supply and normal operation
of the boiler should resume when the
