off the top of the burner ports
(if they are too blue, adjust
the air control).
Lifting Flames
Burner Ports
(holes)
Lifting flames indicate
insufficient draft (restrictor
is set too high).
Ghosting Flames

insufficient air (restrictor set too
high, air shutter shut down, or
other venting error).
Flickering Flames

indicate excessive draft
(move air shutter to a higher
position).
