    I'm not sure about the 40, but I think the 60 and 80 have two nozzles. I know some people have experimented with blocking off one of them to get a more useful heat output level.

    Ditto. The whole idea of these things to get the heat into the water. Anything that inhibits that is robbing efficiency. I do mine every 3 to 4 weeks... after I notice about a 50 degree rise in my average flue temps.

    I would appreciate pics if possible on thermocouple placement. Is blower control (TC #1) automatic or manual?
    Are temps from thermocouples free air temps? How are thermocouples attached/wires riuted? Thanks.
