A little background on me, not a certified stove installer, I’m a master plumber in Massachusetts( highly up our buts with regulations) and always follow the installation instructions. I’ve run metalvent and all fuel flues in my 30+ years in plumbing. I’m building my own house, my third, and will be installing and building the alcove for a Blaze King wood stove. I’m totaling up a bit more than $7000.00 before labor for the pipe, fittings and stove . Will be looking at the 26% tax credit. My question is, as labor can be included, can I charge , and put it into the total , My Labor ?
