    1. For �ro�er o�eration and a��roval, the valve must be installed in the vertical �osition as trimmed from the factory. DO NOT modify the factory assembled trim exce�t as described in this technical data sheet.

    2. A 12” section of �i�e is �rovided with the G-3000P Electric Release Preaction System Riser Assembly. Prior to valve mainte-nance, this section of �i�e may be removed to �rovide clearance for lifting the cover from the body.
