I have recently had a Spirovent and Spirotrap installed on my boiler.
On the Spirovent (I think it is model number UA022W), the installer left a little plastic screw in the vent hole. However, I have been getting air collecting in one of the radiators and I’m wondering whether the screw is meant to be there in the Spirovent? Or is it preventing it from working?
I’ve looked at the installation instructions and they seem to show that the screw is used when pressure testing the unit but is removed for normal use. Is this correct? Just wanted to check before removing the screw in case it causes a leak.
