| What size of flue do I need
for my woodburning stove? Flue size is determined by
either Building Regulation Document J or the size of flue
outlet on the stove, which ever the greater.
The flue must not
be smaller than the flue outlet on the stove.
If the stove is to
be used purely for smokeless fuel the the smallest
allowable flue diameter is 125mm ( 5" ) subject to
the above limitation and 150mm ( 6" ) for stoves
burning wood - except stoves with Defra Smoke control Approval which have a 125mm minimum
diameter or the stove collar diameter whichever the
greater.

registered dealer can advise you.
Beware! Cheap
Internet liners are a false economy and should be
avoided.
