Conduit fitting with integrated condensate trap

Abstract

A conduit fitting for an exhaust duct includes a conduit and a condensate trap. The conduit fitting defines an interior space partitioned into an upper conduit and a lower condensate reservoir. The condensate reservoir can be configured to contain a neutralizing agent for neutralizing acidic condensate prior to it exiting the reservoir.

1 . A conduit fitting comprising:
 a body defining an interior and comprising a partition that at least partially divides the interior into an upper interior portion and a lower interior portion;   wherein the upper interior portion is configured to be a conduit and the lower interior portion is configured to be a reservoir for condensate;   wherein the body defines a conduit inlet and a conduit outlet;   wherein the partition defines a first opening that fluidly connects the upper interior portion to the lower interior portion; and   wherein the conduit inlet is configured to couple to an exhaust outlet of a gas burning appliance.   
     
     
         2 . The conduit fitting of  claim 1 , wherein the partition at least partially defines a second opening located between the first opening and the conduit outlet, the second opening fluidly connecting the upper interior portion and the lower interior portion. 
     
     
         3 . The conduit fitting of  claim 1 , wherein the partition is sloped or curved and is configured to direct exhaust upward toward the conduit outlet. 
     
     
         4 . The conduit fitting of  claim 1 , wherein the body further comprises a reservoir outlet. 
     
     
         5 . The conduit fitting of  claim 4 , wherein the body comprises a base and wherein a lowest portion of the reservoir outlet is disposed at a height that is above the base and below the partition. 
     
     
         6 . The conduit fitting of  claim 4 , further comprising a reservoir conduit, wherein the reservoir conduit fluidly connects the lower interior portion to the reservoir outlet. 
     
     
         7 . The conduit fitting of  claim 1 , wherein the conduit fitting is configured to redirect a flow of exhaust gas at least 45°. 
     
     
         8 . The conduit fitting of  claim 1 , wherein the body is configured such that the lower interior portion contains a neutralizing agent. 
     
     
         9 . The conduit fitting of  claim 1 , further comprising a sensor configured to detect pH of the condensate collected in the reservoir. 
     
     
         10 . The conduit fitting of  claim 1 , wherein the body is single piece. 
     
     
         11 . A conduit fitting comprising:
 an elbow and a condensate collector;   the elbow comprising:   a conduit inlet;   a conduit outlet;   a wall; and   at least one opening in the wall of the elbow,   wherein the elbow is configured to attach to the condensate collector; and   the condensate collector comprising a reservoir outlet.   
     
     
         12 . The conduit fitting of  claim 11 , wherein the elbow comprises a flange extending from an exterior surface of the elbow, the flange arranged to rest on a top edge of the condensate collector. 
     
     
         13 . The conduit fitting of  claim 11 , wherein the elbow comprises a curved surface configured to redirect a flow of exhaust gas at least 45°. 
     
     
         14 . The conduit fitting of  claim 11 , wherein the condensate collector is configured to contain a neutralizing agent. 
     
     
         15 . The conduit fitting of  claim 11 , wherein the condensate collector further comprises a reservoir conduit connecting an interior of the condensate collector with the reservoir outlet. 
     
     
         16 . The conduit fitting of  claim 11 , wherein the condensate collector comprises a base and wherein a lowest portion of the reservoir outlet is disposed at a height that is above the base and below the elbow. 
     
     
         17 . The conduit fitting of  claim 11 , further comprising a sensor configured to detect pH of a condensate in the condensate collector. 
     
     
         18 . The conduit fitting of  claim 11 , wherein the at least one opening in the wall of the elbow permits condensate to drain into the condensate collector. 
     
     
         19 . The conduit fitting of  claim 11 , wherein the elbow is configured to attach to a gas burning appliance. 
     
     
         20 . The conduit fitting of  claim 19 , wherein the condensate collector can be detached from the elbow without removing the elbow from the gas burning appliance.
