To Control Radiators.
Оглавление—When it is desired to shut off steam from any radiator (if the regular radiator valves are used), close the valve tight, and when it is turned on see that the valve is wide open. A valve partly turned off will cause the radiator to fill with water. This rule applies only to one-pipe heating systems.
