what are the 2 channels for on my biasi flue?? one is linked to the exhaust and one to the intake, inspection/maintenance maybe? should they both be tight?
Hope you experts can offer some sound advice
Regards
The right hand one is the exhaust and should be airtight.
Around 2004 there were some problems with tolerances and a few were found to be loose.
If that applies to yours then you could wrap some PTFE tape around the plug or alternatively contact the manufacturers who will post you a metal plug with three rubber seals, a bit of overkill though!
