Lennox 83K09 Heat Exchanger

The Lennox 83K09 Heat Exchanger is a core thermal transfer component used in gas-fired furnaces and boilers to gain heat in the combustion gases and transfer the heat to the air stream or hydronic fluid flowing through the HVAC systems. It is built with heat-conductive surfaces whereby hot combustion is directed and conditioned air or fluid flow around it to collect temperature. It is installed in the combustion chamber of compatible residential and light commercial heating equipment to aid in efficient energy transfer in the maintenance and operation of the system.
