A gas man (who had come for another job) noticed that the flue on my Vaillant combo boiler was not sealed properly and has closed the boiler down as 'Immediately Dangerous'. He says the boiler was installed too low on the wall, which is why the flue isn't sealed properly.
The boiler was installed in 2007 - we have lived here for 14 months and there have been no problems with the boiler (except for low pressure but we think this is from the mains). The boiler was also serviced 14 months ago when we moved in and no problem was then identified with the flue.
The gas man is suggesting we need to replace the flue and lift the boiler up by about 4cm, which will be a big job coasting about 500 pounds including parts.
This seems a bit OTT to me. Can we not just cover the flue with something else (e.g.plastic pipe)?
It'd be useful to have a second opinion about whether it was really necessary to close the boiler down for this issue and also do this expensive work. I've attached some photos.
