Pipe diverting system

Abstract

A roof mounted diverting device for diverting a direction of flow of gas from a roof-penetrating pipe is provided. The roof-penetrating pipe has a central axis. The device includes a diverter having a lower opening and an upper opening, the upper opening having a central axis; and a seal having a seal opening, the seal opening being configured to contact an outer surface of the roof-penetrating pipe and form a gas-tight seal with the roof-penetrating pipe. In an assembled state of the device, any of the gas that enters the diverter can only exit the diverter through the upper opening or through the roof-penetrating pipe, and the diverter is installable in multiple different positions, each of the different positions having a different included angle between the central axis of the upper opening and the central axis of the roof-penetrating pipe.

1 . A device for diverting a flow of gas from a roof-penetrating pipe, the roof-penetrating pipe having a central axis, the device comprising:
 a diverter having a lower opening and an upper opening, the lower opening being sized to surround an end of the roof-penetrating pipe, the upper opening having a central axis; and   a gasket having a seal opening through which the roof-penetrating pipe fits, the seal opening being configured to contact an outer surface of the roof-penetrating pipe and form a gas-tight seal with the roof-penetrating pipe,   wherein, in an assembled state of the device, the gasket is secured to the diverter around the lower opening of the diverter and prevents any of the gas that enters the diverter from exiting from the lower opening around the roof-penetrating pipe, and   the diverter is installable in multiple different positions, each of the different positions having a different included angle between the central axis of the upper opening and the central axis of the roof-penetrating pipe.   
     
     
         2 . The device of  claim 1 , wherein, in the assembled state, the diverter remains out of contact with the roof-penetrating pipe. 
     
     
         3 . The device of  claim 2 , further comprising a mounting plate that is attached to the diverter. 
     
     
         4 . The device of  claim 3 , wherein the mounting plate is removably attached to the diverter. 
     
     
         5 . The device of  claim 3 , wherein the mounting plate is configured to be attached to the roof. 
     
     
         6 . The device of  claim 5 , wherein the mounting plate is configured to extend under an outer layer of the roof when the device is in an installed state. 
     
     
         7 . The device of  claim 1 , wherein the gasket is configured to mount between the roof and the diverter. 
     
     
         8 . The device of  claim 1 , wherein the gasket is configured to maintain the gas-tight seal at different rotational positions relative to the central axis of the roof-penetrating pipe. 
     
     
         9 . The device of  claim 1 , wherein the gasket is configured to maintain the gas-tight seal at any rotational position relative to the central axis of the roof-penetrating pipe. 
     
     
         10 . A system for diverting a flow of gas from a roof-penetrating pipe, the roof-penetrating pipe having a central axis, the system comprising:
 a diverter having a lower opening and an upper opening, the lower opening being sized to surround an end of the roof-penetrating pipe, the upper opening having a central axis;   a gasket having a seal opening through which the roof-penetrating pipe fits, the seal opening being configured to contact an outer surface of the roof-penetrating pipe and form a gas-tight seal with the roof-penetrating pipe;   a first tube section attached to the upper opening of the diverter in a gas-tight manner;   a second tube section that extends vertically away from the roof; and   a connector attached to the first tube section and the second tube section such that the first tube section and the second tube section are attached to each other in a gas-tight manner,   wherein, in an assembled state of the system, the gasket is secured to the diverter around the lower opening of the diverter and prevents any of the gas that enters the diverter from exiting from the lower opening around the roof-penetrating pipe, and   the diverter is installable in multiple different positions, each of the different positions having a different included angle between the central axis of the upper opening and the central axis of the roof-penetrating pipe.   
     
     
         11 . The system of  claim 10 , wherein the gasket is configured to maintain the gas-tight seal at any rotational position relative to the central axis of the roof-penetrating pipe. 
     
     
         12 . A method of diverting a flow of gas from a roof-penetrating pipe that penetrates a roof, the method comprising:
 mounting a diverter to the roof with the roof-penetrating pipe extending into a lower opening of the diverter so that the diverter directs the gas from the roof-penetrating pipe out of an upper opening of the diverter; and   securing to the diverter a gasket that blocks a gap that extends around the roof-penetrating pie between the roof-penetrating pie and the lower opening of the diverter, the gasket having a seal opening contacting an outer surface of the roof-penetrating pipe and forming a gas-tight seal with the roof-penetrating pipe,   wherein the gasket prevents any of the gas that enters the diverter from exiting from the lower opening around the roof-penetrating pie, and   the diverter is installable in multiple different positions, each of the different positions having a different included angle between a central axis of the upper opening and a central axis of the roof-penetrating pipe.   
     
     
         13 . The method of  claim 12 , wherein the diverter remains out of contact with the roof-penetrating pipe. 
     
     
         14 . The method of  claim 13 , further comprising attaching the diverter to a mounting plate. 
     
     
         15 . The method of  claim 14 , wherein the mounting plate is removably attached to the diverter. 
     
     
         16 . The method of  claim 14 , further comprising attaching the mounting plate to the roof. 
     
     
         17 . The method of  claim 16 , wherein the mounting plate extends under an outer layer of the roof when when attached to the roof. 
     
     
         18 . The method of  claim 12 , wherein the gasket is mounted between the roof and the diverter. 
     
     
         19 . The method of  claim 12 , wherein the gasket maintains the gas-tight seal at different rotational positions relative to the central axis of the roof-penetrating pipe. 
     
     
         20 . The method of  claim 12 , wherein the gasket maintains the gas-tight seal at any rotational position relative to the central axis of the roof-penetrating pipe.
