Rain cap vent flue adapter

Abstract

A rain cap system includes a rain cap and an adapter to mount the rain cap to multiple types of gas flues or pipes. The adapter includes a first flange to mount to the rain cap and an adjustable mounting portion to mount to the gas flue. The adjustable mounting portion includes first and second moveable links having first and second surfaces with first and second edges and first and second interfacing portions, wherein the first and second edges define an opening of the adapter. The adapter includes an adjustment portion to move the first and second moveable links towards one another to decrease the size of the opening of the adapter. The adjustment portion is configured to move the first and second links away from one another to increase the size of the opening of the adapter.

         9 . A rain cap system, comprising:
 a rain cap;   an adapter configured to mount the rain cap to a gas flue, comprising:
 a first flange configured to mount to the rain cap; 
 an adjustable mounting portion configured to mount to the gas flue, wherein the adjustable mounting portion comprises: 
 a first moveable link having a first surface with a first edge, and a first interfacing portion; 
 a second link having a second surface with a second edge, and a second interfacing portion, wherein the first edge and second edge at least partially define an opening of the adapter; and 
 an adjustment portion configured to move the first moveable link and the second moveable link towards one another causing a decrease in a size of the opening of the adapter, and wherein the adjustment portion is configured to move the first link and the second link away from one another causing an increase in the size of the opening of the adapter. 
   
     
     
         10 . The adapter of  claim 9 , wherein the adjustment portion further comprises:
 a threaded adjustment portion that is rotatable about a first axis, wherein threading the adjustment portion in a first direction causes the first link and the second to move towards one another causing a decrease in the size of the opening of the adapter, and wherein threading the adjustment portion in a second direction causes the first link and the second link to move away from one another causing an increase in the size of the opening of the adapter.   
     
     
         11 . The adapter of  claim 10 , wherein the adjustable mounting portion further comprises:
 a third link having a third surface having a third edge and a third interfacing portion, wherein the first edge, second edge, and third edge at least partially define the opening of the adapter, wherein threading the adjustment portion in the first direction causes the first link, second link, and third link to move towards one another causing a decrease in the size of the opening of the adapter, and wherein threading the adjustment portion in a second direction causes the first link, second link, and third link to move away from one another causing an increase in the size of the opening of the adapter.
