The boiler is going to be in the basement, so the black pipe should only run from the boiler to the basement celing. I'm planning on putting an adapter between the basement celing and the fist floor then run it through the first floor celing and second floor then up to the false celing then out the vaulted celing as I said earlier it is almost directly at the peak so I wont have much pipe exposed to the cold. Do I need anything special between the first and second floors. I am going to fram in a wall with sheet rock arround it in the first floor for astetics reasons only but not sure if I need any special adapter or if just hanger supports spaced accordinly would be sufficient. Sorry for all the questions. I always seem to start a project like this and then realize that I need somthing else, somthing that I should have known or thought of then have to wast 2hrs running to the store to get more stuff. Just trying to avoid this inevidable event. Thanks again.
