摘要： 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.

摘要： A transistor used as a normally open switch is connected in the millivolt electrical circuit of a fuel-fired natural draft water heater in series with a thermopile device impinged upon by a standing pilot flame, and the solenoid coil portion of the pilot fuel valve. A variable resistance type flammable vapor sensor is connected in a control circuit which is powered by a DC battery and is coupled only to the transistor portion of the millivolt circuit. In the absence of flammable vapor detection by the sensor the control circuit outputs an electrical signal to the transistor that holds it in a closed position to thereby maintain the standing pilot flame. In response to sensor detection of flammable vapor, the control circuit output signal terminates to cause the transistor to return to its normally open switch position, thereby shutting off the pilot flame.

摘要： In a flammable vapor sensor-based shut-off system of a fuel-fired water heater the sensor resistance output signal degradation caused by aging of the sensor is automatically compensated for using an operational timer having an output signal indicative of the total life of the sensor subsequent to its installation on the water heater. In one embodiment of the system, a resistance adjustment signal having a magnitude related in a predetermined manner to the timer output signal is created and added to the sensor resistance output signal in another embodiment, the timer output signal is used to appropriately adjust the minimum-maximum received sensor signal magnitude range, based on the installed age of the sensor, which will preclude combustion in the appliance. Additionally, in each embodiment thereof the system is provided with an improved initial minimum-maximum sensor signal magnitude range. Other types of shut-off gas sensors may be alternatively utilized.

摘要： A baffle for a thermal transfer device can include a body having a multiple first apertures that traverse therethrough, where each first aperture has a first outer perimeter that includes a first base shape and at least one first protrusion extending from the first base shape. Each of the first apertures is configured to receive a tube. The first base shape of each first aperture has a first shape and a first size that is configured to be substantially the same as the first shape and the first size of an end of a tube.
