Generated explanation

The illustration shows a wall-mounted high-efficiency boiler with separate combustion air intake and exhaust vent pipes routed through an outside wall. A blue pipe carries cold return water from the heating system to the boiler, while a red supply pipe carries heated water back to the system through a circulating pump. An expansion tank connects to the supply piping below the boiler. A condensate drain runs from the bottom of the boiler to a floor drain. The diagram states a seasonal efficiency of 90%+ and is simplified for clarity; no defects are identified.
