BURNER FLAME ADJUSTMENTS
NOTE: All burner flames have been adjusted at the factory, occasionally onsite fine-
tuning may be necessary, see below for proper burner flame adjustment.
Flame Characteristics for a Properly Adjusted Burner
A correctly adjusted burner produces a flame that makes contact with the burner and
makes the same contact all along or around the burner. It should be sitting on the burner
and should be dark blue at the bottom and light blue at the top. It should be steady, not
dancing or jumping (indication of too much primary air). This is true for both natural gas
fig. (7A) and LP gas. LP gas may exhibit light yellow tips fig. (7B).
There are several
problems that can happen if the air and fuel mixture is not delivered to the burner
correctly fig. (7C).
