ABSTRACT:
The invention relates to a steam heating system and particularly to a vent control unit for a radiator in a one pipe type steam heating system. The vent control unit includes a thermostatically controlled valve for modulatingly venting air from the radiator to control the entrance of steam into the radiator in accordance with the heating requirements of the room. A check valve which bypasses the thermostatically controlled valve is provided to insure the admittance of air to the radiator during certain light heating conditions when the thermostatically controlled valve may be closed during a period when air must be admitted to the radiator to facilitate proper operating conditions.
