XLO Valve Removal and Replacement

The XLO valves are for the left-most front and left-most rear (simmer)
burners only. When replacing the XLO valve, on some models you
may need to remove the potentiometer together with the XLO valve,
while on other models you may snap the potentiometer off the XLO
valve.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.

Servicing, page 21.
2. Follow all steps in Accessing Components under the Maintop,
page 21.
3. Remove knob from valve stem by slowly pulling knob straight out,
away from control panel.
4. If a burner support rail obstructs access to the XLO valve, then
remove the burner support rail (with jet holder assemblies
attached) by following the steps in Removing the Burner Support
Rail, page 24.
5. While using a 1/2 inch wrench to hold the nut on the solenoid
valve, unscrew the gas tube hex nut with a 9/16th inch wrench.
Then unscrew the other side of the gas tube attached to the jet
holder assembly and remove the gas tube. Be careful not to bend
the gas tube (see Figure 80, page 43).
