<p>An apparatus (1) for conducting hot gases from an exhaust pipe (2) has an elongated flexible conduit (16) with an inlet (8) end and an outlet (10) end. An inlet fitting (22) on the inlet end (8) of the conduit (6) is shaped to tightly engage the exhaust pipe (2). An outlet fitting (42) on the outlet end (10) of the conduit is shaped to direct the hot gases to an object to be heated. The conduit may have a portion comprising a flexible, spirally wound conduit (20) which is flexible when twisted in one direction and locks in a desired position when twisted in a direction opposite the one direction. The inlet fitting may have a seal for fitting exhaust pipes of different sizes. The seal comprises a resilient annular member having a central aperture for receiving the exhaust pipe.</p> |
