Theory Of Operation; Convection Bowtie Baffle - KitchenAid KGRA806P Technical Education

AIRFLOW
The bowtie baffle provides a wider air flow
throughout the oven when using the convec-
tion cooking modes. The baffle, shown below,
is for an electric, Oxford-built oven. The gas
version of the Oxford oven has fewer air out-
lets, which eliminates too much air movement
during cooking (safety).
The correct baffle must always be used when
servicing a gas or electric oven. The oven cav-
ity for Tulsa-built ranges is larger, (4.65 cu. ft.
as compared to 3.93 cu. ft.), and requires a
different baffle.

THEORY OF OPERATION

CONVECTION BOWTIE BAFFLE

Electric Oxford-Built Oven Convection Bowtie Baffle System
In a gas range, the convection fan will not turn
on for the first four minutes of operation. This
is to assure that a proper gas flame is present
before the convection fan starts to circulate air
in the oven cavity.
The fan blows hot air out the baffle along the
outer edges of the oven cavity, toward the front,
over the food, and back into the fan inlet. There
are air slots at the top and bottom of the cen-
ter circle, which adds to the overall air flow
system.
