`
The present invention relates to an adjustable flue connector assembly for use in a fireplace opening to provide a fluid flow channel between the exhaust means of a stove and the chimney of a fireplace opening.
Wood and coal have traditionally been burnt in open fireplaces to produce heat. In recent years consideration has been given to efficient burning of wood or coal in domestic fireplaces. One application for the domestic fireplace has been to insert a stove, commonly referred to as a heater, into a fireplace opening leading to a chimney. The stove usually includes a front cover surrounding the stove which closes the air gap between the stove and the masonry fireplace at the front of the fireplace. The chimney damper is e~ther removed or left in the open position so that flue gases exhausted from l~ the stove flow up the chimney of the fireplace. Frequently, the stove exhaust may not be located adjacent the chimney which usually leads to a buildup of soot and flue gases in the air space between the outer walls of the stove and the inner walls of the fireplace opening. The buildup of soot and 1ue gases has been known to result in unsafe stove operating conditions.
While some attempts have been made to directly connect the exhaust of the stove with the chimney, these attempts have not been totally successful. In particular, one method invloved connecting coiled stainless steel tubing between the stove exhaust and the chimney. The problem associated with this assembly was that often the stainless steel tubing would be of a diameter larger than the width of the damper opening which opening was usually rectangular in , ' ' .
S
shape. As an result the tubing wou]d have to be deformend into an oval shape so that it could be placed within the damper opening which often proved to be an extremely difficult task.
Furthermore, the other end of the stainless steel tubing had to be connected to the exhaust means of the stove. This connection often would be difficult to make due to the usually small or virtually non-existent clearance between the top outer walls of the stove and the top inner walls of the fireplace opening. The installation of this type of flue connector is difficult and cumbersome, and may result in an improper connection leading to the safety hazards previously mentioned.
It is therefore an object of the present invention to provide an adjustable flue connector assembly which may be used readily in most fireplace openings to interconnect the fireplace chimney with the exhaust means of the stove.
It i8 another object of the present invention to provide an adjustable flue connector assembly which may be easily and simply attached between the chimney o the fireplace opening and the exhaust means of the stove irregardless of the clearance between the stove and the fireplace opening.
Briefly, the present invention provides an adjustable flue connector assembly connectable between a chimney of a fireplace opening and a flue gas exhaust means located on a rear wall of a stove insertable into the fireplace opening.
The assembly includes cover means and duct means. The cover means is securable adjacent the damper opening of the chimney and has an orifice of predetermined size to effectively reduce the size of the damper opening to the predetermined size of the cover orifice. The duct means is adapted to extend from the cover orifice and into the fireplace opening. The duct means 17( ).52~
includes inlet means and adjustable positioning means adjustable relative to the duct means for supporting the inlet means at a predetermined position in the fireplace opening.
The inlet means is connectable with the flue gas exhaust means when located at the predetermined position and upon insertion of the stove into the fireplace opening. Once the assembly is connected with the chimney and the stove, the flue gases are exhausted from the stove through the duct means and into the chimney. The adjustable positioning means allows the duct means to be positioned such that the stove may be pressed into contact with the inlet means irregardless of the clearances between the inner walls of the fireplace opening and the outer walls of the stove. Further, the flue connector assembly provides a positive seal between the stove exhaust means and chimney.
While it is within the realm of the present invention to have the duct means comprise a unitary structure or expandable ducting structure, each of which may pass through the cover orifice or be secured to the cover means, in the preferred form of the invention the duct means comprises first and second duct means engageable with one another. The first and second duct means may be slidably engageable and are preferably telescopically engageable. The first duct means may be connected to one of the cover means, second duct means or both.
Additionally, the damper opening may include two flanges and the cover means may comprise a plate which rests on top of the flanges. The plate may include at least one fastening means which can be secured to the underside of one of these flanges in the chimney. It is also envisaged that the cover means may include extensions on the ends thereof such 705i:5 ~~~ that the cover plate can be adjusted to match the size of the damper opening.
The first duct means preferably includes at least one lip which rests on the upper surface of the cover plate and holds the first duct means within the orifice of the cover plate.
The inlet means may comprise a rim which extends outwardly of the second duct means along its horizontal axis towards the incoming stove.
The positioning means of the second duct means may comprise first and second adjustable support means in the form of brackets or the like attached by means of screws to the second duct means. Two support brackets preferably are émployed for the first support means and extend hori~ontally of the second duct means to abuttingly engage the rear wall of the fireplace opening and maintain the spacing between the rear fireplace wall and second duct means. This is important as the brackets prevent the second duct means from moving rearwardly when the stove i5 moved thereagainst. The second support means preferably comprises two brackets which extend vertically downwardly of the second duct means to support the second duct means a predetermined distance above the fireplace floor. The horizontally extending brackets and the vertically extending brackets have a plurality of apertures two of which may be secured to a set o at least two apertures in the second duct means by screws or the like.
For a better understanding of the nature and objects of the present invention reference may be had by way o example to the accompanying diagrammatic drawings in which:
Fig. 1 is a perspective view showing the fireplace opening partially cut away with the adjustable flue connector assembly of the present invention exploded; this drawing is representative of all compon4nts of the preferred embodiment;
-Fig. 2 is an exploded assembly view of the adjustable flue connector assembly, Fig. 3 is a perspective view of the first and second duct means of the adjustable flue connector-assembly;
Fig. 4 is a side sectional view showing the cover plate attached adjacent the chimney damper opening;
Fig. 5 is a detailed view of the cover plate of the adjustable flue connector assembly; and, Figs. 6 and 7 are two side sectional views showing the insertion of the stove into the fireplace opening for connection with the adjustable flue connector assembly.
Referring to the drawings the preferred embodiment of the present inventlon will be described. Referring to Fig. 1 there is shown a fireplace opening 10 having a chimney 12, a rear wall 14, side walls 16, floor 18 and front opening 20. A
stove 22 is shown in Fig. 6 about to be inserted into the fireplace ront opening 20. The chimney 12 has a damper opening 24 at which are located two flanges 26. Below the chimney 12 an adjustable flue connector assembly 28 is illustrated.
Adjustable 1ue connector assembly 28 comprises a cover means or cover plate 30, a first duct means 32 and a second duct means 34.
The cover plate 30 is provided with an orifice 36 and has extensions 38 extending laterally rom the ends of the plate 30. The extensions 38 are adjustable relative to the centre portion 40 of the cover plate 30 by means of slots 42, studs 44 and nuts 45. The plate 30 further includes resilient fastening means 35 which comprise elongated strips of metal 37 astened at one end to plate 30.
:~i7~ 5 .
The first and second ducts 32, 34 are generally rectangular in cross-section and alternatively may be circular in cross-section. The first duct 32 has lips 38 and telescopically engages with the second duct 34.
The second duct means 34 includes an inlet means 48 in the form of a rim 50 extending outwardly of the duct 34 along its horizontal axis 52 (see Fig. 6). The duct 34 further includes adjustable positioning means comprising horizontally extending brackets or support means 54 and vertically extending 10 brackets or support means 56. The brackets 54, 56 are each provided with a plurality of apertures 58 two of which are fastened to adjacent apertures 60 or 62 of the second duct 34 so as to position the inlet means 48 in a predetermined position within the fireplace opening 10 ready for connection with an exhaust means 64 of stove 22.
For a better understanding of the adjustable flue conector assembly 28 and the operation of the assembly, the installation of the 1ue connector assembly is now described.
Firet, a damper plate (not shown) covering the opening 24 of the chimney 12 is removed. Next, the first duct 32 is slid through cover orifice 36 until lips 48 of duct 32 come into contact with the plate 30 as shown. If necessary, the length the plate 30 may be adjusted by moving extensions 38 so that the plate effectively covers the area of the damper 25 opening 24 of the chimney 12. The plate 30 is inserted by angling the plate 30 and moving it through the opening 24 and bringing it back to rest on flanges 26 o chimney 12. The plate 30 rests on the flanges 26 and the first duct 32 extends downwardly from the plate and into the fireplace opening 10.
The adjustable fastening means 35 then may be sprung by a ., ~ 1~7~ ~5i~5 screwdriver to engage the lower side of ~langes 26 so as to sandwich the flanges 26 between cover plate 30 and fastening means 35 and inhibit upward movement of plate 30. Next, the distance from the first duct 32 to the rear wall 14 is measured to provide the proper adjustment setting for horizontal brackets 54 which are then attached to the second duct 34. The distance from the exhaust means 64 of the stove 22 to the floor 18 of the fireplace can be measured to provide the proper height adustment setting for the verticle bracket 56 with respect to the second duct 34 which brackets 56 are attached to the second duct 34. It should be noted that the fireplace shown in Fig. 1 has a porch 66 which is higher than the floor 18 of the fireplace 10. This is only the case in a small minority of ireplaces and measurement for the vertical height is to be taken from the exhaust means 64 to the floor 18 with the stove 22 resting on porch 66. However, in most instances the height above the floor 18 i6 the same as the distance from the exhaust means 64 to the top of the porch 66. With brackets 54, 56 attached to the second duct 34, duct 34 can be slid onto the irst duct 32 by pushing the first duct 32 up through the cover oriice 36, positioning the second duct 34 with the brackets 54 and 56 engaging the respective floor 18 and rear wall 14, and then lowering the first duct 32 relative to the second duct 34 until lips 48 engage cover plate 30. At this time the assembly 28 should be in position within the fireplace opening 10 such that rim 50 of inlet means 48 i8 ready for connection with the exhaust means 64 of the stove 22. Then the stove 22 may be pushed into the fireplace opening bringing the exhaust means 64 into engagement with the the inlet means 48.
Lastly, flange 68 surrounding the stove 22 may be secured to -li7(~525 close the gap between the outer walls of the stove 22 and the inner walls of the fireplace opening 10 at the frant of the fireplace opening. This installation provides a direct connection between the exhaust means 64 of the stove 22 and the chimney 18 and may be assembled simply with the use of a screwdriver or like tool.
Referring to Fig. 7, the stove 22 is illustrated inserted into the fireplace opening. Because of the direct positive seal between the chimney 12 and stove exhaust 64 provided by assembly 28 and because of flange 68 closing the front of fireplace opening 10, a dead space 70 surrounds the stove 22. An advantage associated with the present invention is that the dead space 70 may be packed with non-combustible insulation material, such as for example, fiberglass. As can be appreciated this additional insulation greatly enhances the heating efficiency of the stove 22.
It should be understood that in some instances the depth of the fireplace opening may be such that the exhaust means 64 of stove 22 does not come into contact with rim 50 of the flue connector assembly 28 once the stove 22 is inserted into the fireplace. In this instance, a standard stove pipe may be used as an extension means to interconnect the exhaust means 64 with the rim 50.
