Gas Fires fitted after back boiler removal.

Thanks everyone. So basically a new liner must be fitted first or remove the liner and flow test the chimney?

yep thats it

 

[dancinplumba]

Yep. Iff the flue liners renewed you'll need a flue box.

flue box not required

This might sound stupid but I've never installed a flue liner before. When you buy a flue liner do you get something with it to seal it at the bottom of the chimney just above the fire? I mean so the fumes don't just go up the side of liner and not up the liner?

Is that why you need a flue box?

How do you seal it then, as question above.

Fair one, wouldn't it be simpler to use a flue box though.

 

[dancinplumba]

up to you i guess

 

[Danv44444]

Could be difficult to make sure I won't fall down though
