I'm about to close on my first house, it has an interior old heatilator fireplace (~15ft chimney). I have decided to install a Osburn 2000. I'm located in California (Santa Cruz County). Does anyone know why I wouldn't be able to install it myself. I'm pretty handy and have done a bit of research. I know I'll need to check with my homeowners insurance to make sure they aren't going to use it as a excuse to deny a claim (god forbid). The other thing that may make it difficult is being that it's a heatilator, I'll need to torch out the tubes& some of the smoke shelf to get the liner through.
