I need to wire a propane pool heater. The heater electrical connection is 120 or 240. It requires a 15 amp circuit. The instructions say to never have the heater on without the pool pump running. It even implies that the pump should run for 5 minutes after the heater turns off.
I'm guessing most ignore the suggestion to make the pump run for a short while after the heater turns off. If not, what is a reasonable way to provide that control automatically?
There is a safety switch the instruction call a firemans switch that I have to provide. It interrupts the 24 volt control circuit. Is this just a typical single pole switch mounted in a bell box with an in use cover? Why is this called a firemans switch? Do I also need a service disconnect on the line voltage wires?
