Saf-T Vent CI Plus is the leading commercial double-wall special gas vent system made from superferritic stainless steel. With increased airspace between the inner flue conduit and the outer jacket, today’s CI Plus reduces the required clearance to combustibles and makes a more rigid flue pipe – large diameters are easier to handle.
