receptacles in the burner support rail.
5. Make note of burner support rail placement on the range chassis
(before removing the rails) so you can reinstall afterwards in the
correct position.
NOTE:
It is important to reinstall the correct burner support rails in
the correct position in order to correctly match up the jet holder
assemblies to the gas tubes.
Sharp Component
– Gloves Recommended
The burner support rail has sharp edges. Avoid injury by using gloves
when removing or installing the burner support rail.
6. Using a large flat-blade screwdriver, push one side of the burner
support rail to the other side of the chassis, until the 2 prongs
come out from their slots on the chassis (see Figure 40). Then
remove burner support rail with the two jet holder assemblies
attached (see Figure 41).
Gas Leaks
Carefully check for gas leaks at each gas component that was
removed, replaced, or otherwise serviced using a gas leak detector or
bubble test.
