A portable heater is provided and comprises: a housing provided with a front opening; at least one pilot burner; at least one main burner unit provided within the housing and comprising a front portion facing the front opening of the housing; a gas pressure regulation system connectable to a portable supply of gas; a gas valve assembly mounted to the housing and comprising a gas valve controlling the flow of gas within the heater. Said gas valve assembly cooperating with at least one knob movable along and around an axis for selectively operating the gas valve, controlling the flow an air/gas mixture, and operating a means to ignite the gas/air mixture exiting from the at least one pilot burner. The gas valve being a thermostatic valve provided with means cooperating with a temperature sensor.

Provided is a cooking apparatus. The cooking apparatus has a structure in which cooking modules different from each other are selectively mounted with a free arrangement structure on a top surface of the cooking apparatus.

A cooking appliance is provided. The cooking appliance may include a case, a top plate seated on the case, and a burner accommodated in the case. The burner may include at least one burner pot to receive a gas and air, a combustion member to burn a mixed gas of the gas and air within the at least one burner pot, a burner frame seated on the at least one burner pot to define an exhaust passage, through which the gas burned by the combustion member and carbon monoxide generated by incomplete combustion of the mixed gas may flow, and a catalyst body disposed in the exhaust passage. The catalyst body may have a catalyst to allow the carbon monoxide to react with oxygen.

A heater includes an enclosure, a first baffle plate, and a second baffle plate. The enclosure includes a first wall, a second wall opposite the first wall, and a top plate extending between the first wall and the second wall and cooperating with the first wall and the second wall to at least partially define an interior. The heating module is coupled with the enclosure and is disposed beneath the first baffle plate and the second baffle plate. The heater can additionally or alternatively include an air quality monitoring system and an isolation transformer. The air quality monitoring system includes an air quality controller, at least one air quality sensor, and a power input. The isolation transformer is configured to deliver power from the air quality monitoring system to a fuel system controller of the heating module to facilitate powering thereof.

A cooking appliance is provided. The cooking appliance may include a burner pot having a plurality of mixing spaces and a gas valve device to adjust a flow rate of a gas to be supplied into at least one mixing space of the plurality of mixing spaces.

A vent and a cooker having a vent are provided for which a built-in component accommodated in the cooker is not easily visible from the outside through an exhaust hole provided in the vent, which enables simple manufacturing and assembly, which can smoothly discharge exhaust gas, and has a function as a support structure of the cooker, and a vent structure thereof. The vent may include a main vent configured to be exposed through an upper portion of the cooker and including a main exhaust surface having main exhaust holes and a sub-vent spaced apart from a lower portion of the main vent and aligned in parallel with the main exhaust surface and including a sub-exhaust surface having sub-exhaust holes.

A cooking appliance is provided. The cooking appliance that may include a catalyst device having a catalyst that allows carbon monoxide to react with oxygen.

A cooking grate assembly configured for use on a portable radiant heater with a front safety grille. The cooking grate assembly has a flat main cooking grate with an upper/inner end and a lower/outer end, a pair of spaced hook tabs extending from the upper/inner end of the grate that attach to an upper part of the grille, and a pair of inwardly-angled key tabs extending from the lower/outer end of the grate. A pair of detachable legs supports the grate from a lower part of the grille, with a rotatable locking connection to the key tabs on the grate at one end and opposed inner and outer hooks at the other end that both support the grate on the grille and provide a nesting flat interlock to the rear face of the grate for storage.

Systems and methods are disclosed that include providing a cooking system that comprises a burner assembly and a heat exchanger, the burner assembly having a high velocity burner configured to provide the necessary high velocity, volumetric flowrate through the heat exchanger having a first fluid circuit having a plurality of compactly-arranged tubes disposed perpendicularly and interstitially to a second fluid circuit having a plurality of compactly-arranged tubes, and the burner assembly also having a low velocity burner configured to significantly reduce and/or substantially eliminate lift off that could result from operation of only the high velocity burner.
