I'm stumped with the amount of space I need to leave for the floor of the vent. I read (and reread) James' sticky posting about size of the hearth.
I'm planning a 36 inch oven. The formula James posted translates to :
36"(floor)+9 (walls)+6 (vent floor)+5 (rear insulation)+.5 (one wall)+12 (landing)= 68.5".
After looking at all photos I could find of the vents and floors, it looks like the majority of the floors are 12" to 18" under their brick arches vs the 6 inches used in the formula. Am I misinterpreting the 12 inch oven landing portion?
I'm getting ready to pour the vermiculite concrete portion of the hearth on a corner installation and want to make sure that I get enough coverage under this area., but not necessarily cover unnecessary areas as Vermiculte is hard to find around here.
Can somebody please turn on the lights for me?
Many thanks
