QUESTION FROM Confused in Bristol

I'm a bit confuse about which valve should remain open after I'm finished removing the air from my baseboard radiators. Do I leave the valve above the circulation pump open or closed, or do I leave the valves below the circulation pump?

Thank you!

ANSWER FROM HOME-WIZARD

Dear Confused in Bristol:

If your question is what positions should your the valves around you boiler (both before and after the circulating pump) be in after you have finished bleeding the air out, the answer is that the valves should be in the same position as before you started the air bleeding procedure.

Just remember, what you are trying to do, zone by zone, is to let make-up water come in to replace the water (and air) that is currently in the piping for each zone. The fresh water coming in will not have any air in it, and you will let it flow in until you see the water coming out no longer has air in it.

Hope this is helpful. If you still have questions, just let us know.
