How you do it will depend on how the rest of the system is piped. If it is a looped baseboard system then you will have to create its own zone. If it is a MonoFlo system then you can connect it to the existing main, but you will have to use both feed and return Monoflo tees. If you have any other type of system, then you will either have to come back with a description or have a local plumber determine the best installation.
