A non-bypassable catalyst assisted appliance includes, for example, a housing having a combustion chamber therein. The housing has a loading door opening coverable by a door for loading fuel into the combustion chamber, an air inlet opening for receiving an air supply to the combustion chamber, and an exit opening connectable to a flue. A catalyst combustor is disposed between the combustion chamber and the exit opening. When the door of the non-bypassable catalyst assisted appliance is disposed in a closed position covering the loading door opening, gas from the combustion chamber is directed through the catalyst combustor, and out the flue. When the door of the non-bypassable catalyst assisted appliance is disposed in an open position allowing loading of fuel through the loading door opening to the combustion chamber, ambient air entering the loading door opening and gas from the combustion chamber are directed through the catalyst combustor, and out the flue.

Disclosed is a pellet grill. The grill includes a housing with an opening, a pellet bin and a burning bin, the pellet bin being in communication with the burning bin; and the grill further includes an ash clearing pan, the ash clearing pan is positioned in the burning bin, the ash clearing pan is detachably connected to an inner wall of the burning bin, the ash clearing pan is provided with handles, and the handles are fixedly connected to the ash clearing pan. By using the above design, the ash clearing pan is arranged in the grill such that grill ash may be conveniently collected. Moreover, the handles are arranged such that when the grill ash is required to be cleared, the ash clearing pan may be taken out only by means of the handles, thereby improving cleaning convenience and economic benefits of the grill.

A grill top that can be removably attached to a barbecue grill fire basin has a lever that adjusts the height of the rack above the fire basin. The lever handle is located well away from the fire. A ratchet mechanism holds the rack at a selected height, and parallelogram bars maintain the rack in a horizontal orientation.

A combination outdoor ventless fireplace and brick oven system includes a main body with a framework assembly. A fireplace firebox is formed in the framework assembly. An oven firebox is formed in the framework assembly and suspended above the fireplace firebox. A chimney flue is disposed above the oven firebox in the framework assembly. The framework assembly is covered by a refractory heat resistant mortar. The fireplace firebox has an aperture. The system also has a gas line disposed in the framework assembly below the aperture. The gas line is configured to connect the aperture with a gaseous fuel source. A burner pan may be disposed in the aperture.

A versatile pizza oven comprising a cooking chamber with a cooking surface, an external shell, a heat element operationally installed to provide heat to the cooking chamber, a heat guide plate designed to direct the movement of heat within the cooking chamber, a drip tray at least partially located below the cooking surface, and a channel through which grease and/or crumbs can be moved from the cooking surface and into the drip tray. This cooking apparatus may be provided as a modular kit which can be adapted to pair with an existing griddle or grill, rather than a standalone unit. In this embodiment, the heat source is provided by the griddle or grill.

Pellet grills including a control system that implements, manages, and/or controls various ignition-based protocols and/or processes are disclosed. An example pellet grill includes a cooking chamber, a burn pot, an ignitor, and a controller. The ignitor extends into the burn pot and is configured to ignite pellet fuel located within the burn pot. The controller is configured to command the ignitor to activate during a first duration. The controller is further configured to determine, following expiration of the first duration, whether a temperature of the cooking chamber has reached a threshold temperature. The controller is further configured, in response to determining that the temperature has not reached the threshold temperature, to command the ignitor to activate during a second duration.

A mechanism for raising and lowering a cooking surface within a recessed combustion chamber is provided.

A cooking system includes a fire pit having a burn chamber and includes an oven disposed above the burn chamber of the fire pit. The oven may include an open bottom forming a heatable chamber spaced from the burn chamber of the fire pit, with the heatable chamber configured to receive heat from the fire pit. A cooking surface is disposed in the heatable chamber, and an enclosed top is configured to retain the heat. The enclosed top and the cooking surface form a cooking chamber.

Pellet grills including a control system that implements, manages, and/or controls various ignition-based protocols are disclosed. An example pellet grill includes a cooking chamber, a burn pot, an ignitor, and a controller. The ignitor extends into the burn pot and is configured to ignite pellet fuel located within the burn pot. The controller is configured to detect a temperature pattern of the cooking chamber corresponding to a flame out condition of the burn pot. The controller is further configured, in response to detecting the temperature pattern, to command the ignitor to activate during a first duration. The controller is further configured to determine, following expiration of the first duration, whether a temperature of the cooking chamber increased during the first duration. The controller is further configured, in response to determining that the temperature has not increased during the first duration, to command the ignitor to activate during a second duration.

A mechanism for raising and lowering a cooking surface within a recessed combustion chamber is provided.
