It can be done but it would mean moving the lintel i have done it a few times but you need to be very aware of where and combustible materials are many times they are to close already and removing another layer of brick will push it even closer.Hi all, Mr. Mountain Lady here... Would chiseling out a row of brick (effectively making the opening taller) from the fireplace opening be doable, or would this cause other issues with the structure of the lintel?
That will come up to 1" + thinset thickness + tile thickness or about 1.375". 30.5" minus 1.375" = 29.125". The stove pipe would have to slope downhill to clear the lintel which is something you want to avoid. That's why I suggested 1/4 inch plywood and 1/2 inch cement board instead.Or is using two cement boards even necessary?
