Figure id start a new thread on my almost completed install! Bought the house 12 years ago and used the big bullard stove. Wanted something more efficient so bought the shelburne last year. This year i figured i could push it back to where it belonged and one thing leads to another! Rip the brick, might as well install a sliding door now! New header cut the foundation Durarock walls, mud floor and install 400lbs bluestone slab! This section of the house sticks out 5' past the 2nd story, once i ripped the ceiling i thought it would look cool leaving it vaulted! 2 layers of 2" dow board keeping air space and channel against header! Hope it breaths ok! Thanks for all the help on my stove pipe clearance thread!
