How does one do a smoke test on a 4year old Reillo burner. The smoke is just about visible, and in the older models one could adjust a lever on a scale from 1 to 14 to sort this problem . Must one use a special meter for the new models. Thanks. SEAN.

Would you believe, you use a smoke tester...this is basically a bike pump that draws combustion gases through a filter paper, and the carbon particles are left visible...you then compare them on a scale to see how much soot is being produced.
However, its not as simple as that...the pump pressure must be set, the flue must be clean and only then should a full gas analysis be done. The carbon dioxide level should be around 11% as an average.
