Romvoing the top of my Whirlpool Cooktop

Question

Hello folks,I have one of these whirlpool cooktops installed by the builder so I can't find the model number. The problem now the igniters are not working for all for five burners. By reading some of the resolutions here, I think the igniter unit is not working so I want to try to replace the igniter unit. However, I can't figure out how to remove the top. Does anybody have any idea?
