Hi there,Just need to check with the experts here the boiler in question passed flue analyser tests. However the exhaust tube is rusted. There is no replacement available as the model and parts obsolete. Any advise will be greatly appreciated. Thank you

Me personally ar only because you can see condense has run down

Only id if when you test them with your fga you start to get readings

Thank you for your response Yes the fga test came fine I wanted to double check here. I wanted to change the flue exhaust however there is no availability. Will recommend customer to change the boiler.
