Place burner cap gently on top of base so that the
▯
prongs of the burner base fit snugly into the groove of
the burner cap.
Make sure the cap is centered on the burner base and
▯
lies flat and that there is no gap between the burner
base and the burner cap.
Correct Placement for Burner Base and Burner Cap
Corresponding Jet Holder and Burner Base
Gently try to move the burner cap from side to side to
▯
check for proper placement. If placement is correct,
the cap will click from side to side as the prongs hit
the grooved ridge on the underside of the cap.
If the maintop is removed by a certified installer (for
▯
example to check electrical or piping connection) the
panhead screws that were removed must be re-
installed to ensure proper functionality of burners.
