Hey there, new to the forum here. I just ordered a Rinnai RU199en and it seems I’m going to need to run a new 1-inch line to it. The Rinnai has a 3/4 inch fitting for the gas line; would I just use a 1-inch reducing coupling at the point of entry? Or can I run the 1-inch line to the wall where it’s mounted then use 3/4 flex line from the wall to the gas inlet on the unit?
Thanks in advance!
