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 vent-free fireplace heat removal system and accessories for installation of components for same, and methods for removal utilizing same. The system includes components so that when in use, heat generated in the combustion space escapes into the room in which the fireplace is situated, and heat in the room within a determined distance from the fireplace enters a slot, collects in a collection duct, and passes through a heat exhaust aperture to be expelled from the room. In certain embodiments, a fan system enhances the ability of the vent-free fireplace to expel heat.

A linear fireplace system, assemblies, modular units, and related methods that can be installed in a modular fashion at a selected installation location so as to avoid drawbacks experienced in the prior art. The system can include modular linear units, corner units, and/or end units interconnectable to form a modular linear fireplace assembly. The system can include an alignment track system with a track member that receives alignment rails on the bottom of the modular units to axially align the interconnected units. The system can include a combustion air flow passage within the fireplace that maintains a relatively low exterior temperature of the assembly and that allows combustible and non-combustible building materials to be installed against or immediately adjacent to the top and base portions of the modular units of the assembly.

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.

An air baffle unit includes a major housing wall extending in first and second directions to define an exterior side and an interior side, two upper corner output vent openings, first and second laterally opposed side vent openings, and an air intake opening arrangement defined within an intake area along the major housing wall and extending therealong in the first and second directions. The air intake opening arrangement is defined in an intake area and includes first and second pluralities of intake vents positioned within respective first and second open areas of the intake area with first and second closed areas extending between the first and second open areas. The first and second open areas and first and second closed areas each positioned within respective quarters of the intake area. The open areas are displaced relative to each other in both the first direction and the second direction.

A detachable multi-station parallel synchronous and asynchronous control system for a gas oven includes a controller, a plurality of temperature sensors, a solenoid valve, a stepper motor, and a remote control terminal. The plurality of temperature sensors are installed on a plurality of stations, respectively. The controller generates a control signal, and sends the control signal to a driver through a communication network, so that the driver generates a driving signal according to the control signal, and sends the driving signal to a multi-station coordinated control system. The multi-station coordinated control system controls the stepper motor and the solenoid valve of each station according to the drive signal. A sensor is configured to collect position information and speed information of a plurality of target motors and generate a detection signal. A method for using the detachable multi-station parallel synchronous and asynchronous control system is further provided.

A gas oven with stations under parallel or synchronous control includes a plurality of temperature sensors, a controller and a plurality of processing stations. An air intake device includes a throttle valve, a gas transmission pipeline and a main gas valve. The throttle valve includes a combined gas control unit and a gas valve controller. The air intake device further includes an external gas supply source, and the gas supply source is connected to the gas transmission pipeline and a bakeware. The main gas valve and the throttle valve are separately arranged on the main gas transmission pipeline. The plurality of processing stations are provided with a plurality of gas sub-transmission pipelines and throttle valve gas main transmission pipelines, respectively. The gas oven further includes a communication module connected to a remote control to control the oven by way of a remote terminal or a mobile phone app.
