Selkirk® model EFC single wall expandable flex gas vent connector is designed for use as a connector for listed gas fired appliances equipped with draft hoods and other appliances listed for use with Type B gas vent. This new single wall expandable flex connector is designed to simplify a connection between a gas burning appliance and Type B gas vent systems by eliminating the need for a separate draft hood connector, straight pipe and elbows, removing the guess work of height interference sometimes associated with fixed lengths of rigid single wall or Type B gas vent.
