Generated explanation

A building cross section depicts a one-pipe counterflow steam heating system with a boiler below a radiator. Red arrows show steam traveling through the supply main toward the radiator, while blue arrows show condensate returning in the opposite direction through the same piping before descending through a return pipe to the boiler. The supply main is annotated as typically sloped 1 inch per 10 feet up and away from the boiler, and the radiator is sloped slightly toward its supply pipe. A radiator air vent and a main vent are shown, along with the boiler water line, burner, and exhaust flue.
