Generated explanation

The illustration shows the heat exchanger assembly of a pulse-type condensing gas furnace. A finned combustion chamber connects to a looping tail pipe, with gas and air intakes, a flame sensor, and a spark plug identified near its base. An exhaust decoupler is shown as a hollow tank behind the combustion chamber, and arrows indicate the movement of combustion products through the assembly. A finned heat coil beneath the chamber leads to a labeled flue vent and condensate drain. A large upward arrow shows furnace air flowing across the heat exchanger assembly; no defects are depicted.
