Primary combustion air enters the firebox through the combustion air outlets
located on the sides and front of the firebox. It is essential to the operation
of the outdoor furnace that these outlets remain unobstructed. Clean the
combustion air outlets before they become plugged. The side and front air
channels can be removed for cleaning by removing the acorn nuts. Make sure
to thoroughly remove all ash and deposits from behind the side air channels.
