Question for installers and those in the know:
Pentair Mastertemp 300 natural gas being installed. Manual and front line Pentair tech support say 1" is no further than 50' and 1.25" is up to 200 feet. PB does not think this is correct and says my install at 100' is fine for 1". He is validating but I was looking for some insight on here.
Appreciate any info.
