Step 2 - Replace the Orifices

1. Remove the grates and burner caps.
Note: Do not remove the ignitor from the unit.
2. Remove the orifices.
Note: The orifices require a 7 mm socket driver for
removal/replacement. The driver will need to be
inserted approximately 2 1/2" (64 mm) into the
burner cavity to reach the orifice.
Hint: To reduce the chance of the orifice being dropped
from the socket driver, add a piece of foam tape or
adhesive tape inside the socket.
a) Trim a small piece of the foam tape provided with
this kit (about 1/4" x 1/2"; 6mm x 12mm).
b) Fit this so the tape wraps against one side of the
socket so it stays in place.
c) When pressing the socket driver onto the orifice,
the tape will fit to the orifice and help prevent the
orifice from falling out of the socket during
extraction.
