bleeding air from pipes

We have a hot water baseboard heating system, and have been told that we need to bleed the excess air from the heating pipes. How do we do this?

Bleeding Air

Dkukla:

You will have to locate the little BLEED VALVES on each of your baseboard elements; you can do this by removing the steel end covers on each baseboard section; to give yourself more room, remove the front steel panel from the baseboard as well, they snap right off.

The bleed valves are on either end of the fin-tubed elements; they usually have a little slot which a screwdriver, or even a small coin like a penny can fit in; stuff a wad of paper toweling around the base of the valve & open one of the valves by turning counter clockwise; you should get some hissing air, or a trickle of water will come out; if it's air, let all the air out till you get water; close the valve & go on to the next baseboard.

Do the baseboard first that are located at the HIGHEST point in the house, then go on to do the lower level ones.

A few systems don't have air vents on the baseboard; these systems usually have an older non-diapragm EXPANSION TANK in the cellar & are designed to "accumulate" the air & return it to the tank.

Please post back if you can't find the bleed valves.

Post back if you cant find bleeder valves on the baseboard there. could be your boiled is set up where you have to purge it at the boiler. If all your baseboard are hot then you are ok.
