For my LAARS LT400N, the manual indicates that I need to run a 1.5" pipe over to the heater since the span is 50-60 feet. However, my gas meter is 3/4" and the heater is 3/4". Is it practical/normal to use 1.5" pipe for distances that are 50-60 feet? What have you pool experts seen/installed? Or, do you run 3/4" pipe and crank up the pressure at the gas meter and then regulate it back down to a lower pressure at the heater?
