A retrofit firebox assembly includes a frame, a floor, and sidewalls. The frame has a plurality of vertically extending spaced apart tube members to which solid masonry units are mounted. The back wall has a metal plenum member with a lower vertical portion, a lower angled portion, a central vertical portion, an upper angled portion, and an upper vertical portion, positioned to form a smooth, symmetrical bulge in the back wall extending into the firebox. The solid masonry units are positioned on their respective frame members using clips that position, align, and support the units. The metal plenum provides spaces for air to flow into the firebox between the lower vertical portion and the lower angled portion; and between the lower angled portion and the central vertical portion.

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 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 fire pit assembly having a combustion area along an upper portion of a base, wherein a fan is within the base. An overhanging hood is disposed upward of the combustion area, wherein a passageway fluidly connects the hood and the base so that airflow urged by the fan urges air above the combustion area into the hood, through the passageway, and out exhaust vents in the base disposed below the combustion area.

One embodiment of a pipe universal connector having pluralities of conduits (25, 33, 35) which communicates with other pipes (63), appliance (67) and access bin (39). At least one or more conduits consist of flexible material that can instantly adjust-on-demand to desired angle, offset, turns and positions, making this connector able to replace a T-pipe, Y-pipe and more. In addition, damper (27) and gutter (53) inhabits the intersection (59) to control access to energy and environmental modules, debris, draft and downdraft movement.

A vented campfire tarp is provided that includes a base portion and a plurality of vents formed in the base portion, wherein each vent allows for air, smoke, and carbon dioxide to pass through the vent from one side of the base portion to the other. The vented campfire tarp also includes securing devices to couple the base portion to a ground surface over a campfire. In use, the vented campfire tarp covers a campfire and controls a burn rate of wood of the campfire in response to controlling airflow through the plurality of vents of the vented campfire tarp.
