Hi All,
I am getting a difference of opinion on my gas line size needed for a new tankless gas water heater.
Model is a Navien NPE-210A
At the location it will be installed I have a 3/4" line which comes off of a 1" line. Further down the 1" line is my furnace. On the 3/4" line is a gas dryer and gas cooktop.
One quote is taking 1/2" line off the 3/4" to the new water heater.
Other quote is to replace the 3/4" with a 1".
So which contractor is getting this right?
Thanks!
Steve
