We recently had a new gas boiler installed and have a question on the air scoop/air vent installed at the boiler. Our system has hot water baseboard heating - 4 zones on one (boiler) circuit with a Taco zone control.
At the boiler, there is a Taco air scoop installed with an (automatic??) air vent mounted on top of it. This vent is closed, and the tech said it should be closed unless we hear noise. Then we should temporarily open it.
Is this correct? Shouldn't it be open to allow air to be released from the system? How would the air scoop work if the vent is closed? I am thinking it should be open for a month or two at least to make sure all of the air is purged?? Then close it?? Or should it be always closed?
