In a new house with a great pool with Pentair Intelliflo VS, and Nautilus FNS filter. No heater. I just put in a gas line today and bought a [FONT=arial, sans-serif]Pentair MasterTemp HD 400 BTU heater. Not a lot of room for the heater but planning to put it on the right side of filter (not squeezed between wall but in front around the corner). Do I loop the outflow pipe from the filter 180 deg or is there a way to rotate the base of the filter so the outflow comes out to the right rather than on the left (same side as the inflow). then I assume there is a different valve to get to replace the backwash valve. Ill move the salt cell after the heater and a check valve. But just curious on any better ways to configure this.[/FONT]
