A method of controlling a gas furnace comprising a gas valve for supplying a fuel gas to a manifold; a burner through which the fuel gas discharged from the manifold passes; an igniter for igniting a mixture of fuel gas passed through the burner and air; and an inducer for generating a flow in which a combustion gas generated by the burning of the mixture is discharged to an exhaust pipe via a heat exchanger, wherein the gas furnace performs a heating operation according to a heating signal or a heating stop according to a stop signal, includes the steps of: (a) receiving any one of the heating signal or the stop signal; (b) transmitting a signal to operate the inducer when the heating signal is received; (c) operating the igniter; (d) transmitting a signal to open the gas valve; (e) detecting whether the gas valve is opened or closed; (f) detecting a flow rate of the fuel gas in the manifold; and (g) displaying a normal operation of the heating operation, based on information detected in the steps (e) and (f).

A cooking appliance and method may generate one or more audible and/or visual indications to a user of various gas burner states during the operation of a gas burner, including, for example, states that are associated with different types of ignition operations, such as initial ignition operations, programmed re-ignition operations and/or flame loss re-ignition operations and/or states that are associated with ignition operations, normal operating conditions, and/or failure conditions.

A cooking appliance and method generate an audible and/or visual indication to a user when a user control for a gas burner is in a position within which an igniter is active and a gas valve is supplying sufficient gas flow to the gas burner to support ignition and thereby assist a user in properly positioning the user control during ignition of the burner.

A furnace system of a heating, ventilation, and/or air conditioning (HVAC) system includes a burner assembly having a burner enclosure configured to receive a fuel for ignition to generate heated combustion byproducts. The furnace system also includes a controller configured to detect a value associated with a wave signal transmitted through the burner enclosure and operate the furnace system based on a comparison between the value and a threshold value.

An improved gas fireplace hearth provides a controller and can perform new features. A pressure sensor may be provided to communicate to the controller to warn of a drop of inlet gas pressure to indicate a problem with gas service rather than the hearth. An ambient temperature sensor can provide an input to the controller for various features including a safety feature to shut off gas flow if the hearth becomes too hot. The hearth can be made more efficient by having the controller implement a zero voltage alternating current system to adjust the speed of the fan, flame height, lighting, BTU output or other feature.

The present disclosure addresses systems, media, and methods of configuring a heating system comprising a plurality of combustion-type heating devices fluidly coupled to a vent system. Configuring the heating system includes receiving operating pressure data from one or more pressure sensors in a flue of one of combustion-type heating devices and the vent system. The operating pressure data from the one or more pressure sensors is indicative of a pressure at a corresponding location in the vent system. Configuring the heating system further includes comparing the operating pressure data to stored operational pressure data indicative of operational pressure ranges indicative of permissible operating parameters associated with preventing backflow of flue gases into the one of combustion-type heating devices and outputting instructions for a damper to at least partially open or at least partially close based at least in part on the operating pressure data and the stored operational pressure data.

The efficiency of a solid fuel burning device can be increased and the emissions can be reduced with proper monitoring and guidance. At least one memory and processor can receive information related to operating conditions of a solid fuel burning device from at least one sensor and filter that information and determine a property related to usage of the solid fuel burning device based on fitting the filtered information to a set of reference conditions. The property can be compared to a lookup table comprising triggering events and when the property satisfies one of the triggering events appropriate guidance for operation of the solid fuel burning device can be retrieved and outputted so that alterations can be made to the operating conditions of the solid fuel burning device.
