How do you ground a portable generator?

I have a Wen Power Pro 3500. It says to ground it. There is a wire attached to the ground component. What do I do with the other end?? I have to connect my oven to it for holiday cooking (circuit blew and won't have electrician here til after XMas), is there an extension cord out there that connects those big appliance plugs??

PS I am waiting for owners manual before I operate, but want to be a step ahead in planning.
