I am considering installing a multifuel stove, my only concern is that I will have to install the flue system through a 13" external cavity wall. What are the full dimensions of the 125mm dura flue 135 degree prolonged tee piece and is it a twin wall system?

Hi Lisa,
Thank you for your question.
The 125mm 135 prolonged tee piece is twin wall.
The length of the "diagonal" is 782mm (30 13/16 inches).
I have sent you our flue design sheet which shows 4 common options for fitting twin wall.
If you pick the one that best suits your needs and fill in all the dimensions, our stove team can compile a full shopping list for you.
Send your completed form to sales@directstoves.com
Hope this helps?
Kind regards,
