I didn't see the make/model of your specific heater, so google that model and see what the instructions are for installing.

I don't have the model handy but I know for sure that it was an indoor model and has two large ports on the top for intake and exhaust. It uses 4" PVC that gets routed to a single vent that can be mounted on the roof or side of the house.
