I'm assuming the one you have is electric? Installing ovens are pretty easy. For a dual fuel one, you will need to run a gas line and the proper electrical hookup to the area of the stove. I'm not sure what you are referring to by a "splitter". If you have a gas line that goes by the area where you stove is, you can install a 'T' in the line and then the proper fittings that will connect to your stove. Generally the stoves I have hooked up come with a threaded line that you will have to thread into your stubbed out gas line. I always just read the manual online ahead of time to figure out what size is needed.
