I purchased a home earlier this year and it has a pool heater, Hayward H400. Every time I browse threads for this, it's always about the newer ones with LED's and digital thermostats. Mine has a mechanical thermostat, the one with blue on one end and red and the other and no other knobs. Where can I find the manual for it (it's not the one on hayward site, since the pic is different). Also, what do I need to do to for it in order "close it" for the winter. I know I need to drain it and shut off the gas to it. Anything else?
