Before beginning, make sure you have the proper
tools for the task.
This task requires:

1. Remove both grills from over the main burners
and set them aside.
2. Remove both fl avor grids from above the main
burners and set them aside.
3. Remove the air shutter access panel, located
under the right side rigid shelf, using a Phillips-
head screwdriver.
4. Release and remove the stainless steel clip,
which holds down the back end of the burner,
using a screwdriver. Retain the clip.
Note: Be sure not to lose the air shutter or air
shutter spring, which will become detached
when the burner is removed.
5. Remove the burner by lifting the back of the
burner up off of the inner liner shelf while pulling
the front of the burner away from the orifi ce. Set
the burner aside.
6. Remove the orifi ce using a 3 /

with a deep socket.
Note: The drill size is stamped on the face of
each orifi ce.
7. Replace the orifice with an orifice of the
proper drill size as listed in the Product Data

8. Replace the burner by fi rst sliding the open end
over the new orifi ce and then lowering the back
