    Default Unusual surface rusting

    This system was installed in a dry environment and had some light surface rusting on the burner feed. No other rusting was noted.

    I was not able to identify any issues with the system but wanted to see if anyone has run into this before.

    The system is 9 years old.

    I've seen that on some units when conditions are basically dry. I think it is the type of steel they used for the supply pipe. Is that a Rheem unit? I asked a supplier about it a few years ago don't remember the answer though.
    I tell clients to have the hvac tech clean it off during the seasonal clean & check.

    It's a Weatherking which I believe is manufactured by Rheem /RUUD.

    Cool Re: Unusual surface rusting

    Probably just plain steel instead of aluminized steel as seen in the cabinet around it. It does speak to the humidity levels in that home during summer.

    Keep the fire in the fireplace.

    It is a seam welded formed steel pipe that when manufactured has a light oil on it, once the oil has dissipated the steel will rust.
