<DIV class=moz-cite-prefix>Lanny,<BR>I understand the comment below but I
think flame height can be shortened with excessive excess air. The lowest
emissions CO/CO2 and highest temperatures, at some power levels, in appliances
that I have tested has often been when there is a significantly taller tail of
flame. <BR><BR>However, don't believe all tall tails
