A twist-lock appliance adaptoris an available option that must be used inconjunction with the Simpson Dura-VentDirect Vent system.3) Put a bead of silicone inside the outersection of the adapter and a bead of MillPac on the inner collar. Slip the adapterover the existing inner and outer flue collarand fasten to the outer collar only with the3 supplied screws (drilling pilot holes willmake this easier). Level the fireplace andfasten it to the framing using nails or screwsthrough the nailing strips.4) Assemble the desired combination of pipeand elbows to the appliance adaptor andtwist-lock for a solid connection.Note:a) Twist-lock procedure: Four indentations,located on the female ends of pipes andfittings, are designed to slide straightonto the male ends of adjacent pipesand fittings, by orienting the four pipeindentations so they match and slidein to the four entry slots on the maleends, Diagram 1. Push the pipe sectionsDiagram 1Diagram 2Note:a) The horizontal run of vent must be level,or have a 1/4 inch rise for every 1 footof run towards the termination. Neverallow the vent to run downward. Thiscould cause high temperatures andmay present the possibility of a fire.b) The location of the horizontal venttermination on an exterior wall mustmeet all local and national buildingcodes, and must not be blocked orobstructed.
