    which hayward H400?

    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?

    23K gallon, IG, Vinyl, Hayward DE-3600 Filter, Raypak 406A Heater, Hayward 1.5HP SP2610X15 pump aka AO Smith UST1152, TF-100 Test Kit

    That is an H400 with a pilot light ignition system.
