  • Chimney lining and venting apparatus for use with emissions from an appliance, and method of assembly
    Patent number: 7798891
    Abstract: A venting apparatus includes a projecting member with a projection base, and a mating socket member with a socket base, and first and second ducts in fluid communication with an appliance to vent emissions along an emission flow path. The projection base engages a first one, and the socket base engages a respective other one, of the first and second ducts. The projecting and socket members have default configurations. The projecting member is movable from the default configuration towards a deflected configuration, and biased for return therefrom. The first and second ducts are movable between sliding and locked configurations. In the sliding configuration, the projecting and socket members bear against one another, with the projecting member removed from the default configuration. In the locked configuration, the projecting member is in the default configuration, and secured to the socket member, such that the second duct securely engages the first duct.
