I received an estimate for running black iron 30ft. $250 - $300 by the gas company. Told me two hours labor at $100/hr. + supplies. I received the same quote from a local plumber.
Located in Madison, WI
I was confused when I first read the instructions because the reznor instructions has the horizontal venting sloping downward. I did install it sloping upward.
Now just waiting for the gas line to be installed and I'm in business.
I'm installing a 75k Big Maxx and the instructions say to install the horizontal venting at 1/4 rise per foot. Shouldn't this be a 1/4 drop terminating outside vs. a rise?
