Does anyone know of a good site or want to take the time to type the steps for bleeding the zones of a hot water boiler.
The system I need to do has the bypass, tank and pressure on the return side, then the pump, the pump might be after the boiler I will have to check, then the boiler then out of the boiler to the manifold split into a ball valve, zone valve, ball valve, tee with boiler drain valve then out around the loop then back.
1. Do you have to run the pump while bleeding?
2. Do you bleed each zone one at a time?
3. What about the pressure when you are done do you need to do anything to bleed off the house water pressure?
I've plumbed several system using engineered plans, but always left the flushing and bleeding and electronics to the heating companies. I have to replace a couple of damaged baseboards in a garage and figure I should get a little info on flushing and bleeding that zone myself. I think there are 5 zones total on the system. I didn't plumb it.
