Hey all, I’m in the process of closing down an inground pool for the first time. I’m pretty much done, with the remaining thing being the heater. I can’t for the life of me figure out where the drain plug is. My best guess is a square bolt as seen in the pics. That thing won’t budge at all though. I did blow all the water I could out of it with my cyclone pump, but is there the potential for damage still if there is a bit of water in there that the drain needs to let out?

Thank you for the reply! I have been studying that diagram and going back and forth to my heater several times, I am not seeing the part where it is labeled "Open Petcock". There does not appear to be anything down there on my model

Seems like thos is an old model and doesn't have the small drain plug shown for today's models. I'd just loosen the outlet side and blow through the heater. Any remaining water will surely flow out but don't expect much if anything if it was blown out before this last step. Leave the square plug alone.
