Hi, I just bought a house and looking to take out the gas fireplace and install a wood burning fireplace insert with a metal chimney , but I want to wrap it with block and brick so my question is how thick of a concrete slab should I pour and how should I tie this in to the existing foundation.
Thanks

Mecum, New guys always get toyed with, especially if we see the slightest Homeowner tinge.

The forum here likes you to do an proper intro prior to firing away with questions so we may get an idea of your occupation and skill level.

Bare with us till we figure this out....

No your not confusing me and If I would stud it I put cultured stone up but what I want is a good 2 to 3 hour fire rating between the house and the stack and I already have the C.M.U and the brick left over from a big job last summer.
