Sharp lookin install does the tile make a protected surface with an air gap or is it right on the wall? What pipe and what stove? If that ceiling is just wood maybe you can snap some lines to make a square and cut it out with a multipurpose tool put some hinges and a bolt latch. After all the work i did i was pissed i payed someone to install it was the easiest part of the whole job!
The tile makes a protected surface as I already meet all clearances to combustibles, and is right on the wall over a layer of Durock. The hatch idea is something I'll need to look into, I like the concept. Don't second guess yourself on the install cost. the stove will pay that back over and over, and i bet if you hired someone to do the whole job it would have been $$$$ especially with the copper, and I doubt it would have been as good of a job. Stove is a Pacific Energy Summit.
