Trane EXC01322 Gas Heat Exchanger Assembly W/Combustion Fan & Gas Valve 150 MBH

The Trane EXC01322 Gas Heat Exchanger Assembly With Combustion Fan and Gas Valve is a heating unit of HVAC systems, furnaces and assembled units with 150 MBH ratings. It is a serpentine heat exchanger in which combustion gases transfer the temperature with incoming air, the proper gas valve that controls the flow of fuel, and the combustion fan that maintains the optimal air/fuel ratio and exhaust. It is installed in the furnace combustion part and is connected to the blower and control system. Air is transported through ductwork to be constant during the heating cycle in HVAC systems.
