Mfr Part#: 400-4
Taco Hy-Vent® Air Vents are simple, easy to use and install and are compatible with any heating system. For best performance, use them in combination with Taco Air Scoops, which feature a 1/8" outlet on top. The vents are easily serviceable by simply unscrewing the vent cap.
Do air vents have to be mounted upright or can they be mounted sideways or upside down too?

Air vents should only be mounted upright since they have an integral float which will only function properly in a vertical position.
