Recently the L shape gas connector of my rubine hob broke into pieces. I guess it's just wear n tear problem since i used for quite some time now. Then i bought a replacement parts contain of the connector that comes together with the gas pipe, and it's being glued, so i can't separate it. The problem is i can't find any way to dismantle the hob to get access inside and change the gas pipe. Can anyone help me with this? Really appreciate it!
