Hi Christian - no there's no flame.

off, there's noise coming from it when water/heating is selected, which
is
why I thought there was a pump in the boiler, and the outside vent is
making
it usual noise.

That is probably the fan.

The boiler has one simple thermostat and the little inspection window,
even
with the cover off (which I can gain access to), it looks like an
electronic
ignition, instead of a manual one (had one before).

Does the flame ignite?

Christian.
