Hi,

I'm about to install a woodburning stove. It will need an external twin
wall stainless steel flue on an outside wall. I have a few questions
and would be grateful if any experts can answer them.

My stove has an 8" outlet. Can I use 12" flue outside rather than 8" ?
( I can get some 12" cheap !)

Will this increase or effect the 'draw' in any way ?

I plan on slightly less than 1 metre of stove pipe above the stove
going into the 12" Flue pipe. Does this sound reasonable ?

Thanks

Stu
