Siemens ER94331HK, Installation And Operation Instruction Manual, Page: 17 / 32

As shown in the below picture, please make sure that the
knobs, burner heads, caps and supports have been installed
correctly. Incorrect installation will seriously affect the normal
use of the product and shorten its life-span.
When installing the supports and burners, the user should
pay attention that the protruding objects on the bottom of the
supports and burners are aligned with the stretching slot on
the faceplate, which is used for maintenance. If you place the
components randomly or rotate them for hob placement, the
stainless steel faceplate may be scratched. The appearance
damage of the gas hob resulting from such installation
operations is not covered by our warranty.
