i have a hot water heating system that sprung a leak and now that i stopped the leak seems to be full of air. Do I bleed the system with the furnace running or turn it off? I tried to bleed it with it running but the pipes clank like they are gonna blow! So I tried with the furnace off but then nothing seems to happen.
