hi all - i hope you can help me resolve the fine sooty dust being produced by my heatslave.
my oftec oil/aga/rayburn specialist has applied plumba flue sealant around the flue/boiler coupling twice but i still get fine soot being produced. 2 hours running time will produce a fine layer on the surfaces close to the flue.
it is sited an our pantry (4'x9', 9' ceiling), originally with a balanced flue and no problems.
following an extension, it has been converted to a conventional flue, ~4m with two 135 degree bends. the pantry has a 4" pipe bringing fresh air to floor level and a 200cm2 high level vent to the kitchen. there is a 10x10cm hole cut in the bottom RHS of the boiler side panel. could air flow still be a problem?
my oil tank is ~20m away, at ground level. could this lead to sooty issues?
My boiler man is confused as the nozzle & filter are both clean, and the readings say it is burning efficiently and clean.
i'm considering removing the bottom section of flue, cleaning all joints, and re-sealing from scratch. i cannot detect soot coming from the panel blanking the old balanced flue exit. could that be possible?
so why is there soot, and where could it be leaking from?
your thoughts and advice would be welcome!!
