how to use cook top (cooking range oven ,grill baking ) plzzzzzzzzzzzzzzzzzzz

HI all,
I have a cooking range appliance of a brand name called NIKAI.
I use the cooking gas only to cook food, but iam very much interested in baking cakes, grilling chicken and meat in the griller.
the top part of the cooking range has a normal gas cooking facility,
But the below part consists of a griller and oven. We need to connect the electric connection for the oven part
If anyone has baked cakes, cookies or even grilled any food in the cooking range please let me know as to how do u use it. i already read the manual but i just want to know from another person's point of view.
regards,
