Hey guys, I just discovered this site while planning a renovation of our laundry room and family room. Thanks in advance for any help or advice. We live in Bridgewater, NJ.
We're doing a lot of projects, but the one I'm currently stuck on is the extension of our gas line to our wood burning fireplace. We want to install a gas fireplace insert for convenience. We have natural gas in the house, which starts with a 1" line coming off of the meter and reduces down from there. There is a good spot to tee off the line and run an extension to our fireplace, and I am trying to calculate the various diameter requirements all the way back to the meter.
I intend to submit a permit, and I'm looking for plumbers to do the work, but it has been challenging because everyone is renovating these days, so I may end up running the gas line myself.
I put together this diagram and calculation as accurately as I could.
Looking at this guide for NJ and using the longest length method with the Pressure Drop = 0.5 in. w.c. chart, my concern is that I will need to increase the diameter of my gas line at the meter from 1" to 1.25". But I'm not certain that I'm doing it correctly. Here are my concerns:
- I need to confirm which chart is correct for my area using black iron pipe. Is that something the town would tell me?
- I could not determine the input BTUs for our range. Looking at it, only output values were listed, so the value I have in the sheet is a guestimate
- Should I use a different method of calculation vs. longest length? It looks like the branch length method has the same initial calculation for the pipe diameter at the meter
- Is there anything else I am missing?
Thanks a lot if you read all the way to this point.
