The adjustment for the lower burner air supply is
factory set and must not be changed. A properly
adjusted natural gas burner has a blue flame
around the burner bend with no yellow tips on
the flame. A propane gas burner may have a

Air Shutter opening on factory J Burners is preset
and welded. If replacing the J Burner, verify this
opening before installing it.
