the burner pedestals (wire feed not necessary).

Screw driver for valve screw setting

A flat-head screwdriver with an 1/8" [3.0 mm] wide, .020"

4. Remove the bezel-mounting screw located to the right
of the valve stem, using a T-20 Torx driver.
5. To engage the valve screw, insert the included flat-
blade screwdriver with 1/8" blade into the hole in the
bezel created by removal of the mounting screw. You
should feel the engagement of the screwdriver and the
valve screw.
6. FOR STANDARD BURNERS, adjust the valve screw
by turning the valve screw clockwise about an
1/8 turn. Adjust the valve screw as little as required to
reach satisfactory simmer results. Due to normal
fluctuations in gas pressure, over-adjustment of valve
screw may affect flame stability.
7. FOR EXTRALOW BURNERS, auto-cycling of the
XLOW burners allows for exceptional simmer results
and adjustment is not required. However, adjustment
to the valve screw may be performed to suit individual
preference. Always turn OFF the power to the
appliance before adjusting flame settings. Turn the
valve stem to the LOW position for proper access to
the valve screws through clearance holes in the
potentiometers.
