Hey everyone, I am almost finished with mortaring dome and have started thinking about my chimney design but want to make sure I have this right before I start. Right now I am building a 36" ID Oven and I have the vent transitioning from the outer arch to a 10x10" area where I will mount a Durvavent 6" Anchor Plate for a SS 6" opening Chimney Pipe. My question is: Is there a specific height that the brick vent area needs to be, before the pipe? Right now from bottom of where arch starts transitioning to vent -- to where the mounting plate would be is 7.5". Is that ok? Or do I need to add a few layers of brick to increase this?
Also random question. I have been using HeatStop50 mortar for my oven. On the outer Arch + Vent transition, should I use the same mortar or standard "S" type structural mortar?
Thanks again for any insight here.
