Patent number: 6964248Abstract: A gas-fired water heater is provided with a combustion shutoff system which precludes further combustion within the water heater's combustion chamber in response to a combustion temperature therein reaching a predetermined level correlated to and indicative of a predetermined, undesirably high concentration of carbon monoxide present in the combustion chamber. In various illustrated embodiments thereof, the combustion shutoff system is operative to terminate further combustion air inflow to the combustion chamber, or terminate further fuel flow to the burner portion of the water heater.Type: GrantFiled: September 28, 2004Date of Patent: November 15, 2005Assignee: The Water Heater Industry Joint Research and Development ConsortiumInventors: Gordon W. Stretch, Bruce A. Hotton, John H. Scanlon, Gary A. Elder, James T. Campbell, Larry D. Kidd, Eric M. Lannes, Garrett Doss, Michael W. Gordon, James M. Martin, James W. Mears, Thomas E. Archibald

Patent number: 6854428Abstract: A fuel-fired, power vented water heater has a combustion chamber with an outer wall portion defined by an arrestor plate in which flame quenching air inlet openings are formed. All combustion air entering the combustion chamber must first pass through an air inlet plenum extending outwardly from the arrestor plate and then pass inwardly through the flame quenching openings into the combustion chamber. The air inlet plenum is provided with a normally closed inlet damper which automatically closes during non-firing periods of the water heater to prevent passage of combustion air (and extraneous flammable vapors, if present, adjacent the water heater) into the combustion chamber, and opens during firing periods of the water heater to permit operative combustion air delivery to the combustion chamber.Type: GrantFiled: June 22, 2004Date of Patent: February 15, 2005Assignee: The Water Heater Industry Joint Research and Development ConsortiumInventors: Bruce A. Hotton, Troy E. Trant, John H. Scanlon, Gordon W. Stretch

Patent number: 6814031Abstract: A gas-fired water heater has a combustion chamber with a bottom wall defined by a perforated flame arrestor plate forming a portion of a flow path through which combustion air may be supplied to a burner structure within the combustion chamber. During firing of the water heater a combustion air shutoff system having a heat-frangible temperature sensing structure disposed within the combustion chamber senses an undesirable temperature increase in the combustion chamber, caused by for example a partial blockage of the flow path, and responsively terminates further air flow into the combustion chamber, thereby shutting down the burner, prior to the creation in the combustion chamber of a predetermined elevated concentration of carbon monoxide.Type: GrantFiled: October 9, 2003Date of Patent: November 9, 2004Assignee: The Water Heater Industry Joint Research and Development ConsortiumInventors: Gordon W. Stretch, Bruce A. Hotton, John H. Scanlon, Gary A. Elder, James T. Campbell, Larry D. Kidd, Eric M. Lannes, James M. Martin, James W. Mears, Thomas E. Archibald

Patent number: 6125839Abstract: An outside air intake hood for receiving combustion air for delivery to a direct vent, fuel-fired heating appliance such as a water heater has an opposing pair of side inlets positionable to face parallel to an outside wall upon which the hood is mounted, an outer side wall extending between the inlets, and an outlet passage with an entry portion facing and spaced inwardly apart from the outer side wall. A generally V-shaped baffle member is positioned within the hollow body of the hood, with an apex portion of the baffle member facing the entry portion of the outlet passage. When the wind is horizontally blowing generally parallel to the outside wall, a side wall of the baffle member deflects the wind-driven outside air entering one of the hood side inlets into the outlet passage in a manner converting momentum of the entering air into pressure in a manner preventing the creation of an undesirable vacuum at the hood outlet.Type: GrantFiled: November 12, 1999Date of Patent: October 3, 2000Assignee: Rheem Manufacturing CompanyInventors: Amgad A.
