Text in the illustration

these heat exchangers are prone to corrosion and build-up of deposits between the fins (fire side)
they also require good water flow through the exchanger to keep from overheating (leading to premature failure) - make sure the circulating pump is operating

inspection tip:
a mirror will help determine what the heat exchanger is made of (copper, cast iron or steel) as well as better determine its condition

gas valve and crossover igniters omitted for clarity

Generated explanation

The illustration shows a serpentine finned copper heat exchanger positioned above gas-fired ribbon burners in a boiler. Arrows identify cold water entering one end and hot water leaving the other, while a gas supply feeds the burner manifold below. An inspection mirror is shown beneath the assembly to help identify the exchanger material and assess its condition. Annotations warn of corrosion and deposits between the fire-side fins and emphasize adequate water circulation to prevent overheating and premature failure. The gas valve and crossover igniters are explicitly omitted for clarity.
