Talked with my pool builder (the owner) today. He was reviewing my pool design (done by their designer) and called and asked why I chose to upgrade my heater from the Jandy LRZ to the LXi model. ($350 extra). He said they have had problems with unstable gas pressure causing the heaters to turn off. He said since its a low NOx heater it can be very sensitive to gas pressure changes. He recommended I go back to the LRZ for more reliable use, but will install what ever I want. I upgraded just because its slightly more efficient.
Anyone here have issues related to gas pressure with their LXi heater? This does concern me a little since I'll be taping into my propane tank the house uses for heat and hot water heaters. I see how I could get pressure swings.
