Generated explanation

The illustration shows a schematic cross section of a hot-water boiler with a side-mounted burner firing into the lower combustion chamber. Cool water is pumped into the bottom of a serpentine, finned heat exchanger, and hot water exits through a pipe at the top. Upward arrows show heat moving from the flame through the heat exchanger into the water. An exhaust flue connects to the upper portion of the boiler and carries combustion exhaust away. No defects or improper installation practices are depicted.
