First post in this sub; hopefully it is ok here.Project is installing an overhead natural gas heater in my garage.Looking at the house from the street, gas main is on the far left of the house outside the basement wall. Garage is on the right side of the house, and I want to put the heater in the very far right side of the garage. So it is quite literally the farthest it could be away from the gas main.Current furnace, dryer and fireplace already run off the existing 3/4" black pipe run from the main, so based on BTU numbers I need to run a new, 3/4" pipe basically from the garage heater all the way back to the main, rather than T off the existing run somewhere. I plan to have a HVAC company T into the main for me but I am going to install the pipe run to the heater as it's rather labor intensive.I plan to run through the basement with a couple of 21ft black pipe sticks and then pop through the wall into the garage. I plan to do a 90 here and then go up towards the garage ceiling with another 3/4" black pipe stick. (I'm now on the left side wall of the garage but still need to go across the garage ceiling to get to the right side wall of the garage). I don't wan't to go across the ceiling inside the garage for aesthetic purposes, I'd rather pop up into the attic (one story house) and go across there and then drop down over on the right side of the garage right where the heater will hang.I'm concerned about having joints in the attic with black pipe where I don't typically go in case there was ever a leak. Would it make more sense to make a joint right below the garage ceiling on the left side wall and attach CSST here and then do a long, no joint run through the attic, and then pop down by the heater, or is it typical to run black pipe through attics as well? Is this really a valid concern? I've also heard about lightning strike issues with CSST and that concerns me as well.Any thoughts? via /r/DIY https://ift.tt/2FRbSQW
