IDEAL ISAR M30100

[sanlibra56]

My ideal ISAR m30100. Started making a bang when lighting. It has had a spark ignition installed over 2 months. It has started banging again two weeks ago, though in the last week not so much.
It does it when hot water only on or when both hot water and central heating on together. Another thing noticed tonight is that it shows C for central heating when it is switched off.

Have you check the condensate trap?
