Problems solved by technology

A disadvantage of present fireplace systems is that it can be particularly difficult to align and attach the flue ducts to the fireplace assembly.
Thus, it can be a very labor-intensive job to simply attach the flue duct to the fireplace during installation.

first embodiment

[0049] The flue plate 255 shown in FIG. 5 is the same as that described in the For example, it has two cylindrical extensions 260, 270, and these extensions 260, 270 are slightly smaller in diameter than the ducts 130, 140. The extensions 260, 270 also define openings or apertures in the flue plate 255. These openings create the necessary pathway in the flue connection member 250 to allow the exhaust or intake air to pass from the fireplace to the flue ducts 130, 140.

[0050] The flue connection member 250 is preferably coupled to ducts by sliding the ducts over the cylindrical extensions 260, 270 and coupling the ducts to the cylindrical extensions 260, 270 by mechanical attachment, such as a collar with a screw-tightening member. The flue plate 255 may also have notches (or slits) 275 for aligning and connecting the flue plate 255 to the fireplace 100.

[0051] The flue plate 255 has a top surface and a bottom surface. The top surface of the flue plate 255 faces flue ducts 130, 140. ...

second embodiment

[0062] Fireplace connection member 420 is similar in structure to that of the fireplace plate of the However, certain differences are necessary because of the co-axial nature of the ducts 330, 340. For example, there is a single opening or aperture 470 in the fireplace plate 425, and there is a single seat 485 that surrounds the opening 470.

[0063] The rest of the elements shown in FIG. 12 are the same as those shown in FIG. 5. The fireplace plate 425 also has two latches 491 that pivot about a pivot member 492. The latches have a slot 493, and within the slot 493 is a bolt 494. The pivot member 492, slot 493, and bolt 494 define a curved path of travel for the latches 491. The fireplace plate 425 has several tabs (or extensions) 490. Tabs 490 match up with the notches 375 in the flue plate 355. If desired or required by local building code the latches 491 can be further secured by attaching a screw or bolt through opening 495. The functions of these elements are the same as that de...

fourth embodiment

[0076] The remaining elements and the method of operation of the flue connection system of the fourth embodiment are the same as that described above with respect to the previous embodiments.

Abstract

A flue connection system for an appliance provides a flue connection member. The flue connection member defines an aperture and includes an extending member. The flue connection member is configured to be coupled to a flue duct and an appliance, including a fireplace. An appliance connection member may also be provided for attachment to the appliance. The flue connection member and the appliance connection member are configured to be coupled to one another with the flue connection member positioned in contact with the appliance connection member.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a flue connection system. More particularly, the invention relates to a system for attaching a flue duct to an appliance. BACKGROUND OF THE INVENTION [0002] Appliances, in general, especially fireplaces are often attached to ducts to facilitate the exchange of gases and air to and from the unit. For example, a common design of a gas-fired and wood burning fireplace includes a combustion chamber that is vented through a flue duct. An example of this design is described in U.S. Pat. No. 5,452,708, the disclosure of which is incorporated herein by reference. Some gas-fired fireplaces also include a duct for drawing intake air into the combustion chamber. The fireplace is connected up to the flue duct or intake air duct during installation. [0003] Factory-built fireplace assemblies have long been available as both free-standing and wall recessed units. Traditionally, when a fireplace insert is installed into a home or other ...
