Boiler noise

[bilco_21]

Hi all my friend has got a old boiler called An Ababgas 50 wall mounted boiler an seems to be making a chattering noise when boiler is firing. I understand this an old boiler and no information with it I was just wondering if anyone had had experience with this type. This had been no problem for the last 20+ years!! Any help would be appreciated!! I

Never heard of it but all good things come to an end. Whoever makes it, spares won't be easy to source. Might be time to bite the bullet.
