No. 71 Air Vent Valve

1/4inch male connection MPS, 150psi

The No.71 Auto Vent (automatic hot water air vent) is designed for use on hot water radiators, baseboards, convectors, radiant panels and small unit heaters with a maximum working pressure of 150p.s.i.

Instructions: Valve screws vertically into 1/4inch I.P.T. by hand (do not use wrench), making certain that Cap is screwed down tightly, to prevent scale and dirt from rushing into valve while filling system. After system is filled, loosen cap slightly and allow air to be released slowly, otherwise scale and dirt might rush in causing valve to leak. If this does happen, push down valve stem then pull up lightly to dislodge scale. To shut-off valve, screw cap down tightly. For normal venting, open cap one full turn. Wherever there is a possibility of water damage, use a Maid-O-Mist 7A waste connector and run tubing to nearest drain.
