Buderus making noise (Gas)

Options
My client has a natural gas Buderus G124x-18.



When it fires up it rumbles and makes the "pop corn" sound an old water heater makes.



I tried flushing it out for an hour, until the water ran out clean. The client says its still making the noise.



Any ideas or possibly suggested flushing chemicals I could use to correct the issue?



Thanks in advance,

Mike

    Fernox works good. I get it from Boyertown Supply, Boyertown, PA.

    You can choose to do what you want, but you cannot choose the consequences.
