Cite as Conn. Agencies Regs. § 29-232-83
The return water connections to all low pressure steam heating boilers supplying a
gravity return heating system shall be so arranged as to form what is known as the
"water line return" so that the water cannot be forced out of the boiler below the
safety water level. A recommended connection is shown in figure HG 703.1, section
IV, American Society of Mechanical Engineers Code.
