Wood burner outlet sizes

[LeeUK]

Hi

Installing a wood burner.

The burner has a 200mm outlet, will it be okay to fit a reducer (to 150mm) before adding the pipes through the ceiling and out the roof to reduce costs.

Is this okay or is there a reason for the 200mm, its quite a big burner.

Cheers
Lee

if im not mistaken, there is no min flue requirments. only guide is that the flue shall be no smaller than 15% of the fire opening. if the spigot is 200mm i would go with that unless manufacturers instructions state otherwise. you also require air vents in the room.
