I had solar panels at my old house/pool.
Gas heating where I live now, The heater internal components look clean/newish. I'm planning on taking off the service
cover and inspecting, cleaning any spiderwebs etc before firing it up for my first time this weekend.
My question is this, when the heater is running, if I needed to turn my pump off (pump gets power and is switched on / timer, from heater control panel)
manually, does the heater then turn off the flames and run the pump for a few minutes to keep water from boiling in the heat exchanger, similar to how
a gas furnace for a house keeps blowing for awhile?
Right now if I manually turn the pump off from the control panel, it turns off instantly. (I have never turned the gas on)
I've never worked with gas pool or spa heating so forgive if this is a dumb / obvious question.
