A variable position gas trap apparatus (10) and method to separate gases entrained in drilling fluid (12) in a tank (14). The apparatus includes a gas trap (16) attached to a carriage (20) and a frame (26) attached to the tank (14). A lever moveable by the float rod, activates the control valve to raise or lower the carriage having the gas trap container attached thereto. A feedback control loop is responsive to changes in the level of the drilling fluid in the tank. A mechanism is provided to mechanically and automatically move the carriage with respect to the frame in response to the feedback control loop.
