Generated explanation

The illustration shows a floor-mounted high-efficiency boiler with separate combustion air intake and exhaust vent piping. Blue piping indicates cold water returning from the heating system and makeup water entering from the supply plumbing, while red piping carries heated water to the system through a circulating pump. An expansion tank connects to the heating-water piping above the boiler. A pressure relief valve discharge pipe runs down the side of the cabinet, and a condensate drain leads to a floor drain. The simplified assembly is labeled with a seasonal efficiency of 90% or greater; no defects are identified.
