    I hope I know what you meant but that word made me laugh.

      Looking at the spare parts it appears that the Thermopile will not be replaceable. (I'm not sure on this one but will check the spare parts list Saturday).

      I was looking at the pilot assembly and could not see how to remove the thermopile as it appeared to be pressed in, this will mean that the whole pilot assembly will need to be changed out once the thermopile burns through.

        Thermopile is a small cluster of thermocouples.
        A thermopile is used when you have a higher milliamp requirement. In this case the only source of power for the circuit board and blinky green light is the voltage produced by the thermopile

        ( In case you thought there is no such thing as a thermopile)

          Just finishing installing my 3rd one in two weeks. So far no problems.

          With a Honeywell control that's not too bad.

            Do you mean millivolt?

              because of the fvir sealed chamber, most thermocouples/ piles are a unit with the pilot. it's sealed into a fire/ air tight silicone style grommet.

              the old days of replaceing a $4.00 thermocouple is long gone.

                Yes, actually both would hold true in the case of a thermopile

                  I've installed maybe a dozen icon units thus far, with no trouble, If icon is as good as the 24 volt ttw counterparts, they'll be a big improvement over conventional gas valves.

                  they're easy to repair or replace.

                  The only weakness I can see is, if they ever flood there's no blow out and re-light.

                  It'll be blow out, replace the board and re-light.

                  I'd expect the american/aosmith/state combo company to have an icon-ish system by 2012, if the world doesn't blow up.
