8. Make sure the HSI wire connector has been detached from under
the burner box (per step 5).
9. Remove and retain the screw that secures the HSI onto the burner
box chassis (see Figure 62), and then gently pull the HSI out
(see Figure 61).

4.4.4 Grill Electrode Removal and Replacement
On the grill, the electrode functions as a flame sensor – that is, if the
electrode does not heat up enough in a short time frame, the
electrode will close the solenoid valve to avoid gas build-up in the grill
burner. See Figure 63.
