With the insane amount of money required to heat my home with an oil fired boiler, I decide to go the way of wood heat. So I have had my existing masonry chimney inspected and it is good to go. I have constructed A floor pad and wall pad from 2x4s on end, 2x4s laid flat for support. On top of the 2x4s I have 1/2" plywood, 26 gauge steel, 3/4" Permaboard cement board, and ceramic tile. I have an existing 6" terracotta thimble running through a 12"x12" brick face that I have exposed by removing all drywall with in 20". I plan on running 6" single wall pipe through the terracotta into the flue. I would like to set the stove next weekend. My question is have I missed anything?
