Are you asking how to drain it? If so some older models come with a drain **** located on the bottom side of the black manifold. It is brass. You can loosen the drain **** and the water will drain out, be careful when tightening the drain **** back up though, they can break easily. You do not have to put much torque on it at all, dont even put a tool on it at first, if it leaks, then tighten it a little more. The newer models come with a brass plug instead of a drain **** and you can remove the brass plug. Or the best way i think is to unhook both unions for the inlet and outlet on the heater, use a shop vac on blow, and blow the water out. But if you are winterizing the pool equipment, the heater is not the only thing that needs to be drained.

I need to winterize my Hayward 300. Where the manual shows a drain valve there is a thick square bolt. I'm afraid to compromise it if it is not in fact a bolt.


That is the drain plug...underside of the inlet/outlet header. You should also break open the connection of the water tube to the pressure switch inside the heater to prevent the switch or tube from freeze damage.

How do you winterize a inground pool heater? model# H200ed2 serial# 21130507102557001


Drain it using the drain valve on the bottom-side of the inlet/outlet header; make sure the heater sits level or slightly tilted down on the header side. You also need to drain the water tube that feeds the pressure switch inside the heater cabinet. Turn off the gas and power off the circuit and you are done. If you cover it DO SO LOOSLY! Wrapping it tightly and not allowing air to flow thru will lead to rapid rusting of all the sheet metal.

How to winterize ?


There should be a drain plug on the bottom of the inlet/outlet header. Also, depending on where it is, you should remove the pressure switch and let it drain. Turn the gas valve off. When you blow out the return lines, it should remove the water that's in the heater, after the return lines are blown and plugged, you can then remove the heater drain plugs and pressure switch.

Drain gas heater for winter


On the side of the heater, you will see the water connections. Directly underneath them, on that black component that they attach to, there is a drain plug of some description. It may be a draincock, or just a plug. In either case, simply open or remove it to safely drain your heater. In a pinch, you could also disconnect the water connections at those unions (the big grey connectors), but they can be fussy to reassemble, and you run the risk of losing the o-rings.
