There is a wire coming from the valve unit which attaches to a metal pen looking thing. This broke off at the valve unit and I smell gas. Can this be fixed? What is this metal wire with pen on the end? I have searched the Internet and can't find it anywhere. Any help would be appreciated.

thank you, Deb
