smell of gas from boiler vent

[lizzy33]

Hello everyone.

I've recently moved into a flat and it has a vokera boiler. We've noticed the smell of gas whenever we switch on water, and I've noticed it from another flat as well. We had a boiler check and the engineer didn't find anything wrong or concerning but did not comment on why I'd smell gas sometimes from the outside vent when we used the water. The engineer said the boiler is 3 years old.

Has anyone else experienced this or can give some explanation?

Many thanks in advance

During the ignition process there will be a little unburnt gas released prior to it lighting, that will be all you can smell (Mercaptin). As long as it's been checked and it then disappears after a time then there's nothing to worry about.
