Hrm wallstar starting and stopping but not cutting out

[Aaron M]

Hello all. I have several hrm wallstar boilers and am reasonably familiar with most of their problems but not this latest one.
The boiler will fire and run when asked, albeit running rough and fumey, then it will stop, but not cutout. Wait 10 seconds or so and it will fire up again.
It will continue to do this for perhaps 20 minutes then will stop altogether.
Any ideas greatly received.

Why you letting it run rough and fumey?

I spose I asked for that! I was already aware of that problem and thats being sorted, but its damn cold where this boiler is so need it running regardless. Do youvthink the 2 are related?

You may find once it's set up properly with a flue gas analyser it resolves your issue.
