CONT: Burner Efficiency Tests and Adjustments ... A smoke spot tester is used to measure the soot content of flues gases. The serviceman will adjust the air intake band on the burner until a visually smokeless flame is produced in the combustion chamber. The probe of the smoke testing apparatus is inserted through the hole in the flue pipe and a flue gas sample is drawn through a piece of filter paper. The resulting soot mark on the paper is compared in intensity to a standard chart. The chart shows measurements labelled 0 to 9 and most residential oil furnaces can burn cleanly enough for a 0 to 1 rating ... a number 2 smoke is ideal.
