A fog generating system ( 20 ) includes a fluid feed conduit ( 22 ) and extension tube assemblies ( 26 ) spaced along the conduit ( 22 ). The assemblies ( 26 ) include nozzle fittings ( 40 ) coupled to extension tubes ( 32 ). Misting nozzles ( 44 ) are releasably engaged with the nozzle fittings ( 40 ), and are recessed within the nozzle fittings ( 40 ). Installation entails arranging the system ( 20 ) on an interior side of an installation form ( 90 ), and securing the nozzle fittings ( 40 ) using fitting plugs ( 50 ) so that an open ends ( 60 ) of the nozzle fittings ( 40 ) abut the form ( 90 ). The fitting plugs ( 50 ) further form a fluid resistant seal for maintaining the assemblies ( 26 ) under fluid pressure during installation. The system ( 20 ) is embedded in a concrete material ( 124 ) for the structure ( 120 ). Following removal of the installation form ( 90 ) and the fitting plugs ( 50 ), the misting nozzles ( 44 ) are installed within the nozzle fittings ( 40 ).
