I renctly purchased a used RP2100 millivolt heater from a man than used it 2 seasons then family illness caused them to remove pool. Heater sat in his garage for a couple years, now it's mine. Any advice of where to start? What to check? I know I need to purchase the drain plug(missing) and PVC connectors as well as the nat to propane conversion kit. So while I'm waiting on parts should I do?
What size propane tank do I need?
