Hi all,
I have a new to me F3CB that I have rebuilt from the ground up. It previously had a top exit flue but I'd like it to be rear exit. I have smashed out the opening at the rear and have bought the replacement cover for the top plate.
My main question is, is there a collar or adapter that I need to buy for the rear exit? The top collar is a totally different fitment to what there is at the rear. The rear and side exits both look to have built in internal collars of some sort. There are screw holes/notches to receive something. Whether that something is a 6" tee/elbow or some sort of adapter, I'm not sure. I've included an image below.
I'm hoping the wealth of knowledge on this forum will help get me to where I need to be!
Many thanks
