Gap filling around flue liner

[oscarinnes]

To stop the crud dropping out of the chimney breast onto my wood burner I need to fill the void around the flue liner. Trouble is there’s a bracket which makes it practically impossible to get your hands in and stuff anything into that space. Was wondering if there are any expanding foam type products that could be used in this area? If not then any alternative suggestions would be welcome.

....how to get it in there if I can’t get my hands in

You could try fitting a proper sealing plate, or flue jointing compound. Sounds like it wasn't put in with the greatest of care. Mind you, when wood burners were the norm' and not a fad, people had to clear up the mess all the time.

Pictures would help ,but usually some sort of board or fire cement fills the gap..Do not use expanding foam.
