It's electronic ignition

if it's not lighting, it's buggered

.... although I think you need to find out why it's not lighting

1/ is the overheat stat OK

2/ is the fan running

3/ is the air pressure switch changing over

these are the steps preceeding ignition

The Pottertom Netaheat 'boiler' _does not_ have a
pilot light ..... (as such)
the ignition sequence is;-
electricerky in, starts fan which pressurises the casing ...
the pressurised casing (air pressure switch) enables
gas (solenoid) valve admitting gas to the first burner
and starts a spark across a spark-gap; this should
cause the gas to ignite with a solitary flame ... this heats
a thermocouple which energises a solenoid admitting gas to
the main burners which will 'catch' from the initial burning
flame - and Bob's your Uncle; - main burner aflame.
The sequence occurs every time the boiler is turned on and off.
btw; unless you're going to over-ride the logic of the device
it's not possible to (normally) get a flame without the casing
on, secure, and providing a pressurised 'innards.


If your Netaheat isn't lighting when you turn it on ...
you've got a problem ....;-
is there electricity?
is there gas?
does the fan come on when the boiler is energised?
[You'll hear this, or feel it through your hands on the casing]
[A knackered fan assembly is a common reason for
the boiler deciding not to bother going any further]
can you feel the duct outlet?
is there any trace of a smell of (unburnt) gas?
can you hear a 'click-click-click' of the spark
across the spark-gap?

Depends on whether it's a netaheat or a Netaheat electronic
