Why don't you phone trianco up and talk to russ in technical and he'll help you also give the boiler a good scrub out I went to one of these and found the baffles tight due to build p of muck on the baffle supports cleaned them off all ok ( just a thought)
Oil Boffin,
I don't know whether you have read my previous posts, but attacking the baffles with an angle grinder is very much a last resort.
I commissioned two 'identical' boilers in this range, and they suffered from the sooting up from the outset. I was in contact with Trianco, while they still were Trianco, to query several points in the specification.
The manuals had different settings to the labels on the boilers, which were both different, and the configuration of the combustion heads was different on each burner. One had a break plate behind the diffuser, and the diffusers were both different.
Upon comparing the baffles, there was a marked difference between items which should have been identical, withi a single boiler. After setting up to revised settings given by phone, the problem persisted, and my customer was not in agreement with my suggestion to 'ease' the baffles, so I called in Trianco.
Unfortunately, I was unable to attend when their engineer came, but another tradesman on site told me exactly what had been done, which was the baffles were opened out with an angle grinder. Their engineer however, declined to communicate this to the customer, only saying that now the boiler had been set up to the recommended settings he should have no trouble. My customer assumed that I did not know what I was doing, so consequently I lost him, and several others who he told about my 'incompetence'.
I was quite pleased to see Trianco fold up.
