TM 5-3895-374-24-2 7. High turn down ratios are a distinct advantage of internal bypass systems.  It is possible, however, to adjust for a low fire so small that the flame is being “chilled.” The fire will  look  excellent  and  appear  bright  and  uniform,  but  a combustion efficiency test  will reveal high smoke content and  low  CO2.    To  correct  this  situation,  increase  the  oil  flow  or decrease  the  air,  or  both.    Be  sure  to  test  with  proper instruments  to  ensure  good,  clean  efficient  combustion throughout the firing range.
