Description
The York S1-4221000 Flue Outlet Kit is a venting assembly that channels combustion exhaust gases from the heat exchanger to the exterior of a structure through a designated flue passage. It attaches to the outlet collar of the furnace or boiler and provides a sealed pathway that directs byproducts such as carbon monoxide and water vapor away from the occupied space. In HVAC systems, the kit forms the starting point of the exhaust venting run, connecting the appliance to the vertical or horizontal vent stack and ensuring combustion gases exit the building without back-drafting into the supply air stream.
