Remember to fill the baseboard for at least 15 minutes to start off. Locate and mark off the bleeder valves at the beginning itself. Then bleed these valves one by one with a small screwdriver. Only after making sure there are no leaks/air pockets should you turn the power on.
The 15 minute fill time is just a rough guideline, I guess. I prefer to listen and fill - initially you hear the water filling the baseboard and then you stop hearing it when it is full. The pressure at this time usually reads about 12 psi. add a comment
