Remove air from steam baseboard

Hi. How would I remove air from a steam baseboard. Someone told me to remove the air valve, run the system and catch all the water with a bucket and that will clean it out. Is there any truth to this?

    No. If there is water in a steam baseboard you have bigger problems. The water will return as the radiator heats and the water condenses in it. You have to fix whatever is preventing the condensate from draining.

    What could be causing it not to condensate?

    Back up a moment. What are the issues that you are having with that particular baseboard?

    When heat comes on, it bangs and shakes for few mins, then it is fine once it heats up

    Condensate is not draining back . The baseboard needs to be pitch . Properly installed it should be two piped .

    There was an error rendering this rich post.

    I think first we should establish what type of steam system you have; one pipe, two pipe, hybrid, something else?

    Some pictures of some radiators and near boiler piping would be very helpful.

    I have to ask, are we talking about removing water, or air? The first post has me quite confused.
