Rafael,


Your picture was fine. I just never knew that people stored their bicycles next to the water heater flue.

If I remember the picture right it looked like the metal flue joints were connected wrong.(against the flow)

The white powder is a soot created by the environment of unburnt gases, condensation, air. You can see this in furnaces also. Visible in the 70%'ers.

Hi Chuck or whomever


On the water heater post replied to saying unburned gas was the white stuff around the flue pipe is this a concern or can it be avoided?
