Generated explanation

The diagram shows paired supply and return manifolds for a hot water heating distribution system, each with six zone connections. Red piping carries water from the boiler into the supply manifold and out to the zones, while blue piping brings water from the zones into the return manifold and back to the boiler. Both boiler connections have isolating valves and optional temperature gauges, and each manifold has an optional air vent. The supply manifold has flow indicators marked in gallons per minute, while the return manifold has manual or automatic flow modulating valves. An annotation identifies PEX piping as typical and notes that manifolds feed radiant loops or radiators.
