Oven installation: a few key points you need to know
The easiest thing to do when choosing a new oven is to match the size and fuel supply of the new oven to the existing oven.
However, if you prefer to change these features, it usually means you need a qualified electrician or gas plumber to make the proper fuel connections, or a cabinet builder or carpenter to make sure the new cavity can accommodate your new oven.
So the most common process is to match a new oven with your existing one.
The easiest way to do this is to check the make and model of your oven on the data badge. This is usually on the inside of the oven door.
