A drafthood assembly for inclusion within a vent stack for a direct venting stove or fireplace, converting the direct venting stove or fireplace for use with a natural venting flue. The assembly includes an air intake section for feeding ambient room air into the combustion chamber and an exhaust gas section for feeding ambient room air into the products of combustion that are exhausted from the combustion chamber in order to cool the exhaust gas products so that a B-vent type flue can be used to carry the exhaust gas products out of the dwelling.

Drafthood adapter assembly particularly for stoves and fireplaces

A fireplace adapted for attachment to a flue pipe assembly including an exhaust pipe and a surrounding fresh air pipe is provided. The fireplace comprises an interior housing. The interior housing forms a combustion chamber. The fireplace also comprises a top wall, a rear wall and side walls. These walls define an exterior housing about the combustion chamber. A combustion air flowpath is defined within the housing through which air for combustion is brought from outside the housing into the combustion chamber. The fireplace also comprises a top port formed in the top wall and a rear port formed in the rear wall. Each of the top and rear ports include a first portion that communicates with the combustion chamber and a second portion that communicates with the combustion air flowpath. Finally, the fireplace comprises a vent pipe assembly. The vent pipe assembly includes an inlet air pipe member and an outlet air pipe member. The outlet air pipe member is connectable with the selected port at the first portion. The inlet air pipe member is connectable with the selected port at the second portion. The inlet air pipe member further includes a plate portion which overlies and closes an unselected port. The vent pipe assembly is non-integral with the housing and is movable between the top port and the rear port.

Fireplace with vertical or horizontal venting

A gas burner for a fireplace. The burner comprises a burner housing having a grid of openings that are formed from heat resistant material. The housing has a first burner assembly and a second burner assembly arranged therein in a side-by-side relationship, each burner assembly having a chamber with a perforated gas distribution plate. The gas distribution plate is located adjacent the grid. Each of the burner assemblies has a gas mixing area with an inlet for primary air and combustible gas, and air flow controllers e.g. primary air shutters, for controlling the ratio of primary air to gas in the first burner assembly lower than the ratio in the second burner assembly.

Gas burner for fireplace

The invention relates to a direct vent gas fireplace adapted for attachment to a concentric flue pipe assembly having an exhaust pipe and fresh air pipe. A top wall, rear wall, bottom wall and side walls define a combustion chamber. A gas burner is disposed in the combustion chamber. A slanted flue attachment wall is attached to and extends between the top wall and rear wall. The slanted flue attachment wall is disposed at obtuse angles relative to the top wall and rear wall. A first pipe member is orthogonally attached to the flue attachment wall and is in fluid communication with the combustion chamber for conveying combustion products from the combustion chamber. A second pipe member having a diameter larger than the first pipe member is disposed concentrically around the first pipe member. The first and second pipe members define an annular space therebetween forming an air intake duct. A combustion air duct extends between and is in fluid communication with the air intake duct and the combustion chamber for supplying combustion air to the combustion chamber. The exhaust pipe and fresh air pipe are respectively attached to the first and second pipe members and can be selectively oriented to extend away from the fireplace in a substantially vertical or horizontal direction.

Direct vent gas appliance with vertical and horizontal venting

The invention is directed to an induced draft fireplace including a plurality of outer walls defining an outer housing. The outer walls include at least one outer side wall and an outer top wall. A plurality of inner walls define a combustion chamber. The inner walls include at least one inner side wall and an inner top wall having an outlet opening. A room air circulation channel is defined by and disposed between the outer housing and the inner housing. The room air circulation channel has an inlet and an outlet. A heat exchanger is disposed in the room air circulation channel, and includes an inlet connected to and in fluid communication with the outlet opening, and an outlet. The heat exchanger includes a plurality of walls defining at least two flow paths extending in different directions, the at least two flow paths defining a total change in flow direction within the heat exchanger of at least 180.degree.. A fan having an inlet is connected to and in fluid communication with the heat exchanger outlet. The fan also has an outlet for connection to a flue for transport of products of combustion from the combustion chamber.

Induced draft fireplace

A heat producing gas log apparatus includes a blower having an inlet and an outlet for circulating air through the log apparatus. A gas burner has a plurality of openings for emitting combustible gas to produce a flame. At least one air supply channel has an inlet opening and an outlet opening. The inlet opening is disposed at the front and bottom of the heat producing gas log apparatus and receives air, and the outlet opening is in fluid communication with the blower inlet. At least one heat exchanger tube is disposed above at least a portion of the gas burner and has an inlet end and an outlet end. The inlet end is in fluid communication with the blower outlet, and the outlet end is disposed generally coplanar with the inlet opening of the at least one air supply channel at the front and bottom of the apparatus.

Heat producing gas log apparatus

A gas fireplace burner assembly which produces a yellow flame and simulates the appearance and pattern of the yellow flames produced by a natural wood log fire includes a log grate for supporting a plurality of artificial logs. The log grate is formed with a stepped configuration and has a back wall and opposite side walls, each of which has an opening formed through its thickness to allow secondary air to pass therethrough and into an interior space defined by the walls of the log grate. The log grate also includes a slotted grate front member. At least a front and rear artificial log is supported on the log grate. A burner tube is also supported by the log grate and has front and rear portions which are disposed in parallel. A front flame deflector is interposed between and spaced apart from the grate front member and the front portion of the burner tube and defines first and second channels for secondary air to flow through. Artificial ember material is situated adjacent to the front burner tube portion and is further situated so as to be adapted to come in contact with flames emanating from the front burner tube portion. A rear flame deflector is at least partially superposed over the rear burner tube and has a plurality of flame openings formed in it. A gas control assembly controls the passage of gas through the burner tube, and includes a gas valve which communicates with the burner tube and which can be coupled to a source of gas.

Yellow flame gas fireplace burner assembly

Method and gas burner assembly for producing among the arrangement of non-combustible logs, and essentially yellow flame pattern with substantially low levels of carbon monoxide production. In general, method hereof employs a gas burner assembly having one or more burner each having a plurality of gas jets. The burner assembly is disposed between the combustion chamber of fireplace enclosure which contains a predetermined volume of combustion chamber air which is continuously provided from outside of the combustion chamber. Non-combustible fireplace logs are arranged above the gas burner assembly so as to provide one or more flow paths between the burner and adjacent logs, for allowing free flow of combustion chamber air through the flow paths and about the burners. Flow of gas is provided through the burners so that the gas flows out of the gas jets and mixes with the combustion chamber air about the jets of the burner. Combustion chamber air flowing through the flow paths and about the burner is concentrated so that the flame pattern has essentially a yellow color, and the logs above the burners are maintained at a sufficient temperature so that combustion gases flowing out of the fireplace exhaust have substantially low levels of carbon monoxide. In the preferred embodiment, an H-shaped burner is used in practicing the method of the present invention.
