The fireplace includes a hearth suspended on a support. The hearth is defined laterally by a peripheral wall that is equipped with at least one combustion air inlet. There is a discharge pipe for discharging the combustion gases, that includes a bottom portion secured to a top part of the hearth, and a top portion opposite the bottom portion. The fireplace also includes at least one combustible fluid burner that is arranged in the hearth opposite at least one air inlet and a combustible fluid supply column that extends between a first end connected to a combustible fluid source and a second end connected to at least one burner. The supply column passed down through the discharge pipe from its top portion to its bottom portion and opens in the hearth in order to convey the combustible fluid from the combustible fluid source to at least one burner.

A cooking appliance includes a secondary venting arrangement within an oven cavity to supplement a primary venting arrangement with localized venting of combustion products adjacent a flame detector that detects a flame emitted by a gas burner disposed under the oven cavity. Doing so may assist with stabilizing the flame generated by the gas burner prior to establishment of steady state flow pattern within the oven cavity.

A fire pit has a gas burner and a repellent container. The gas burner provides energy that volatilizes repellent from the repellent container.

A kiln includes a stage, a stove, a gas supply assembly, and a combustion device wherein, the stage includes a stage body and a carrier member. The stage body has a first chamber, while the carrier member is detachably disposed at the stage body. The stove is joined to the stage body and has an entry and a second chamber. The gas supply assembly is disposed at the stage body, and part of the gas supply assembly is located in the first chamber. The combustion device is located in the second chamber. The carrier member can be detached from the stage body and be moved out of the stove from the entry so that the first chamber communicates with the second chamber. In this way, the working space inside the kiln can be increased, which is convenient for users to repair and maintain the gas supply assembly or the combustion device.

A gas stove, including: a stove body, a range hood, a closed stove, and an exhaust system. The closed stove is disposed in the stove body. The closed stove includes a heat conduction panel, a burner, and a thermal insulation and guide device. The thermal insulation and guide device is disposed around the burner. The heat conduction panel is disposed on the top of the thermal insulation and guide device, and a combustion chamber is formed therebetween. The range hood is disposed on the stove body. The range hood includes a fume absorption inlet for receiving oil fumes formed in the process of food cooking. The stove body includes a fume release channel. The fume release channel communicates with the fume absorption inlet. The thermal insulation and guide device includes a smoke outlet for discharging hot smoke in the combustion chamber.

A cooking appliance includes a cooking area. A hob can be located in the cooking area. The hob includes an injector holder base defining an air chamber and a burner interface chamber. An injector holder cover overlies the injector holder base. The injector holder base and the injector holder cover collectively define a venturi tube extending between the air chamber and the burner interface chamber. An injector is carried by at least one of the injector holder base or injector holder cover. A burner is supported on the injector holder cover.

A gas burner for a cooking appliance includes a body defining perimeter and having a plurality of first groups of respective pluralities of first outlets a plurality of second groups of respective pluralities of second outlets. Each of the first outlets respectively defines a first outlet area, and each of the second outlets defines respective reduced outlet areas that are less than the first outlet area. Further, the first groups and second groups are alternately arranged around the perimeter, and a total number of first outlets is greater than a total number of second outlets.

A convection outdoor or indoor gas heater is provided, the heater comprising: a top; a first wall; a combustion chamber which includes a vent cap with a plurality of vents, the vent cap proximate to the top, the combustion chamber housed within the first wall, spaced apart from the first wall to define a first interstitial passageway, the first interstitial passageway in fluid communication with the plurality of vents; a gas burner assembly which is housed in the combustion chamber; a second wall spaced apart from the first wall to define a second interstitial passageway, the second interstitial passageway in fluid communication with the first interstitial passageway; a base which supports the first wall, the second wall and the combustion chamber; a combustion air inlet in fluid communication with the combustion chamber; an ambient air inlet in fluid communication with the second interstitial passageway; and an outlet in fluid communication with the first interstitial passageway.

A burner assembly for a domestic gas cooktop includes a lower burner mounting structure positioned on a first side of the top sheet; a burner body configured to be positioned on an opposite side of the top sheet, the burner body having an igniter positioning surface; an igniter having an igniter end, and a stop integrally formed in the igniter, the stop having an upper ledge; and an urging member that pushes against the lower burner mounting structure, and urges the igniter in a direction away from the lower burner mounting structure and toward the igniter positioning surface such that the upper ledge of the stop is urged into contact with the igniter positioning surface when the burner assembly is in an assembled condition. The igniter is held in an operating position by the burner body and the urging member when the burner assembly is in use.

A portable propane fuel heater assembly for heating a room with propane fuel includes a fuel tank that contains liquid propane. A supply hose is fluidly coupled to the fuel tank for receiving gaseous propane from the liquid propane. A heater is provided and the heater is positionable in a room in a building. The supply hose is fluidly coupled to the heater thereby facilitating the heater to receive the gaseous propane that gaseous propane from the liquid propane. In this way the heater can burn the gaseous propane for heating the room in the building. Additionally, the heater has an exhaust duct for venting combustion gases outwardly from the heater.
