and wondered what the recommended distance is from the floor channel vertical secondary air tube and the heat riser port entrance?
Many thanks for any help.

Hi John;
My secondary tubes have the 6" stub set back apx 1"
The tube itself is even with the back wall.
So I would say 3/4" - 1.5" would be acceptable.
