    Larr's pool and spa heater model help

    I took the back panel off to check for model number and spider webs and dirt etc.. I see no information panel for model number or BTU's and such. Can someone help me find this info. I want to be informed if it needs service and question that I might have to ask on here as well. I bought the house with everything installed but no manual was found.
    Thank you Everything is working great !

    Re: Larr's pool and spa heater model help

    Is there a thread on pool heater maintance . I read in the manuel something about a filter, but I'm not sure if it meant the pool filter or if the heater has a filter. It blows quite a bit of hot air out the exhaust so I'm assuming it has to draw it through some kind of filter. Please forgive the noob question .

    Not a ton of people on here during the winter months but be persistant and eventually people will come out of hibernation
