Abstract: A mechanical type boot including a vertically positioned riser in a tubular configuration with an outwardly flanged upper end and an outwardly flanged lower end. Vertical bolt holes are provided through the ends. Vertical bolt holes are provided in a lower flat end of a base flange. Vertical bolt holes are also provided in a flanged lower end of a generally cylindrical split seal cap ring. Vertically extending bolts couple the riser, seal and base flange. An inverted J-shaped tube constitutes a gas well pipe. The tube has a long vertical section located within and extending upwardly from the split seal cap ring. The next intermediate section extends outwardly. A third outboard section extends downwardly for the exhaust of gasses. The lowermost end of the gas well pipe is held in a fluid type relationship with regard to the split seal cap ring.
