2004, Balance flue.
Exhaust fumes in room, only noticeable as a door is now fitted in to the door way, it was a kitchen but will be a bedroom.
4" Rubber O ring seal with burner onto baffle box and rectangular rope seal on top of baffle box would benefit from replacement.
What is the best way to check?
Are there other joints to check apart from those above?

 

Don't use it and call in a pro for your own safety. That's the only advice we're allowed to give on the open forum. Them's the rules.

 

Needs completely resealing for safety and then a leak test carried out.bob

 

Please turn it off immediately and get a professional in

 

A professional will do a leak test to isolate the problem. A leaking flue will normally lead to lockout if the BF box is fitted which leaves you with the access seal, but there are other potential areas.
