A wood stove monitoring and control device can include a mounting flange mountable to a chimney exhaust pipe of a wood stove. The device can include a ring removably mountable on top of the mounting flange, where the flange is suitably positioned vertically along the exhaust pipe so that the ring is positioned at least partially above an end of the exhaust pipe. The device includes an optical beam source disposed on the ring, and which generates and outputs an optical beam. The device includes an optical sensor positioned on the ring opposite the optical beam source to detect the optical beam output by the optical beam source as the optical beam passes through smoke exhausted by the wood stove through the exhaust pipe. The device can include a temperature probe disposed on the ring to measure a temperature of heat exhausted by the wood stove through the exhaust pipe.

A heat and flame control assembly for a grill or other cooking appliance. The heat and flame control assembly includes a main heat plate and a slider plate disposed above the main heat plate. The main heat plate includes openings that allow direct heat to be provided to the food. The slider plate is movable with respect to the main heat plate, and also includes opening. When direct heat is desired, the slider plate is movable to align the openings in the slider plate with the openings of the main heat plate. However, when indirect heat is desired, the slider plate is movable to cover the openings of the main heat plate.

A separate heat absorbing mass is secured in co-planar abutment with a bimetal strip controlling a fireplace damper to absorb heat from the flue gases. The mass transfers heat to the bimetal strip during the OFF cycle thereby delaying the opening of the damper and increasing the heat retention and efficiency of the fireplace.

A sealed chimney damper is provided for preventing flow of air between an interior and exterior of a structure through a chimney. The sealed damper includes a damper body having an inlet aperture and an outlet aperture; an upper flange formed around the outlet aperture of the damper body; a valve plate hingedly secured to the damper body adjacent the outlet aperture, the valve plate sized to substantially cover the outlet aperture when the valve plate is in a closed position; and a gasket secured to the upper flange of the damper body and surrounding the outlet aperture, wherein the gasket is positioned between the valve plate and damper body when the valve plate is in a closed position.

A damper, damper kit and method are for installing a damper in a duct defining a gas conduit. The damper kit includes a first aperture closing unit engageable with at least one conduit wall and configured to close a first aperture when engaged therewith and including a shaft receiving section opened in the gas conduit. The damper kit has a second aperture closing unit engageable with the at least one conduit wall and including a shaft receiving section opened in the gas conduit. The damper kit includes a damper having at least one shaft with a first section insertable in the shaft receiving section of the first aperture closing unit and a second section insertable in the shaft receiving section of the second aperture closing unit and extending past the at least one conduit wall through the second aperture closing unit.

A motor-actuated actuated-vent-valve is configured to operatively couple to a vent port of a solid-fueled cooker. The vent port is in series with both a flow of air into a combustion region of the cooker, and a flow of resulting combustion gases from the cooker, the flow of air being responsive to a position of the actuated-vent-valve. A first controller adapted to receive a sensed-temperature signal responsive to a temperature within a cooking region of the cooker, and operatively coupled to an externally-located actuator motor of the motor-actuated actuated-vent-valve, provides for automatically electronically controlling the position of the actuated-vent-valve to a continuum of positions within a range of the positions, thereby substantially regulating the first temperature within the cooking region of the solid-fueled cooker to a user-defined temperature level responsive to the sensed-temperature signal by controlling an exclusively-naturally-occurring flow of air into the combustion region of the cooker.

A catalytic cookstove, for use in cooking, heating, and lighting, is disclosed for reducing particulate matter and carbon monoxide emissions. A non-platinum group metal catalyst promotes oxidation of particulate matter and carbon monoxide to produce carbon dioxide. Additionally, a passive damper automatically adjusts the fuel-to-air ratio based upon the size of fuel fed to the stove to ensure catalyst light off.

A floor and an upright sidewall formed from two vertically coaxial components, each component having a floor baffle with a plurality of floor openings defined therein, each floor retained within a respective upright sidewall with a plurality of sidewall openings defined therein. The floor openings and the sidewall openings cooperate between the two coaxial components such that flow of gases through the floor and upright sidewall of the baffle structure is controlled by rotation of the two vertically coaxial components relative to one another.

A vent assembly that increases air flow and temperature control for outdoor cooking/smoking appliances, which effectively controls the space/gap for air exit, so as to improve air flow through the chimney and to increase temperature ranges and control within the smoker/chimney. The vent may have a gasket to make the grill waterproof and prevent mold when the grill is not in use. The vent can pivot or slide in one direction to ensure it does not open completely, so as to lose the air flow setting when the grill cover is opened or tilted.

An actuated vent valve external of, and in series with a vent port of, a solid-fueled cooker is automatically controlled by controlling a flow of air into a combustion region of the solid-fueled cooker so as to substantially regulate a first temperature within a cooking region of a solid-fueled cooker to a user-defined temperature level responsive to a first temperature signal measured within the cooking region of the solid-fueled cooker.
