Hi,
I was working in the garden last week and I could smell gas. It seemed to be coming from the vent of the combi boiler, which was fitted last year. A couple of days ago I could smell gas again, and this time it seemed to be coming from my next door neighbours combi vent. His was fitted only a couple of months ago.
So, assuming I am correctly identifying the source of the smell, is this normal for a combi boiler? Strange that it should happen on 2 of them (different make, different installers)
