Help diagnosing problem with Johnson Starkey warm air Uyheater please

[Masood]

I'm not very familiar with these, serviced one once with my mentor when I was training, that's my total experience on them. The problem is that it will light, and the pilot will stay on, it will burn just fine for 30 minutes or so, then go out. At which point pilot light goes out as well. It's for a good mate of mine. I won't be doing the work as I don't have my DAH ticket, but I'd like to know what the problem might be so he doesn't get ripped off... Any ideas please?

Think Dsgas might be thinking of TTB causing cut out.

Definitely check out flue and also circulator if fitted

I don't know mate - haven't been to have a look, just spoken to my mate over the phone about it. I don't think I'll be doing the work myself as I don't know the units or have the ticket, but I'll have a quick once-over and post on here for someone who knows these units well..
