Sold our stove yesterday. It feels odd with it gone but I’ll be picking up the new one next week. With the stove’s heat shield I had worked around a flat panel radiator. I am going to remove the radiator for a straight forward heat shield install. While I have plumbed two houses, I don’t have much of a clue about boiler / hot water heating systems. Here is a pic of the manifold. How do I disconnect the radiator's inlet and outlet lines without screwing things up? Heat circulates fairly well on our main floor and the other radiators should keep up when needed.
