Abstract
An isolation assembly for a boiler unit that incorporates a pressure relief valve and an automatic air vent to a valve body that includes a valve positioned adjacent to the automatic air vent. The unitary valve body reduces the number of components and leak paths and incorporates a ball valve to permit removing and/or securing the automatic air vent without having to purge the adjacent plumbing system.
