I have an ignition lockout problem.

The fault finding flowchart makes referance to 1V dc
at terminal 1 but where is this 1V or 10V referenced To

Earth Neutral or is there some other 0V point.

I have replaced the ignition control unit and the aquastat yet still NO
spark..
Does anyone know the sequence of operation on this unit

also I find an error on the installation manual the NO & NC on the Pressure
switch are the wrong way round I have left these as is.

Can anyone help....

Is the fan spinning?

Problem Solved..

I turned the gas off to check the sequence of operation.

It was quite dark and noticed that the EHT lead was running touching the panel at the bottom, the spark was leaking to earth along where touching
the panel.

I placed some heat resisting material along underneath the EHT wire
it now sparkes where it should.

Thanks for you help.
