What does a Bacharach smoke number of 3 or higher indicate about an oil burner, and what is the target range?
A
A smoke number of 3 is acceptable for oil burners over 15 years old
B
A smoke number of 3 is ideal - it indicates the appliance is firing near maximum output
C
A smoke number of 3 or higher indicates excessive soot production, incomplete combustion, and risk of heat exchanger fouling - the target range is 0 to 1
D
The Bacharach scale only goes to 2, so a reading of 3 indicates instrument malfunction
