Abstract
A combined air intake and combustion gas vent terminal is provided for engagement with at least one of a pair of pipes extending horizontally and being spaced apart to accommodate the inward flow of combustion air and the outwardly flow of exhaust air from a furnace. The terminal assembly is installed entirely outside of the building and has a stepped structure for engaging the pipes such that it can accommodate different sized pipes.
