Definitions

  • This invention concerns a chimney attachment and method of fitting a flue liner in a chimney.
  • a chimney is usually lined by passing a flexible metal tube along the length of the chimney and the liner is usually supported at the top of the chimney by a top support plate.
  • a chimney pot is usually fitted to the chimney top to protect the flue liner and provide a traditional finish to the chimney top.
  • Masonry chimneys are usually porous and moisture may be driven through a brick or stone chimney by capillary action. Moisture entering the space between the liner and the chimney may interact with old soot, sulphurous material and other debris contained in the space to produce an unpleasant smell. Since the inside of the chimney will get hot in use (due to the passage of hot flue gases) the moisture in the space may form malodorous fumes. If there is no other vent for such fumes then the fumes may enter the house via the chimney (for example through the bricks or mortar.
  • the fumes may comprise, for example, gases, water vapour and particulate matter (such as soot or other debris), and the term "fumes" should be taken to be any matter that can be vented.
  • a chimney attachment for fitting to a chimney to support a flue liner in the chimney, the flue liner and chimney defining a space therebetween.
  • the chimney attachment may comprise a support for supporting the flue liner in the chimney.
  • the chimney attachment may be arranged such that connection of the flue liner to the support provides a first outlet in gaseous communication with the flue liner for venting flue gases to atmosphere and a second outlet in gaseous communication with the space between the flue liner and the chimney to vent gases (e.g. water vapour) in the space to atmosphere.
  • the flue liner may comprise a flexible metal flue liner.
  • the flue liner may be constructed from stainless steel.
  • the attachment may constitute, in use, a primary support for the flue liner within the chimney.
  • the attachment may bear substantially the full weight of the flue liner.
  • the attachment may constitute, in use, the only support for the flue liner within the chimney, i.e. the flue liner may not be attached or connected to the wall of the chimney by any other means at any other point.
  • the attachment may be attached to a top end of the flue liner.
  • the flue liner may hang or be suspended from the attachment.
  • the support may be adapted to engage with the flue liner at or close to a top end of the flue liner.
  • the chimney attachment may be advantageous as on fitting the chimney attachment to a chimney and/or chimney pot and connecting a flue liner to the chimney attachment a vent (second outlet) is provided for fumes that may be present between the flue liner and the chimney. Since the vent is effectively built into the chimney attachment there is no need to rely on a worker to drill holes or fit air bricks in the masonry of the chimney, it is a natural consequence of fitting the chimney attachment.
  • the first and second outlets are a common outlet
  • the chimney attachment comprising flue gas and ventilation flow channels, each leading to the common outlet, the flue gas flow channel in gaseous communication with the flue liner and the ventilation flow channel in communication with the space between the flue liner and the chimney.
  • a common outlet may allow an aesthetically pleasing chimney attachment to be formed without parts of the attachment extending beyond the radial width of the chimney.
  • the first and second outlets are separate outlets.
  • the chimney attachment may comprise a wall defining a flue gas flow path terminating in the first outlet, the wall providing a support surface to which the flue liner can be connected, connection of the flue liner to the support surface separating the first outlet from the second outlet.
  • the wall may define a central void, the void providing the flue gas flow path, and may be arranged to be spaced from a chimney or chimney pot to provide a ventilation flow path between the wall and the chimney or chimney pot to the second outlet.
  • the support surface to which the flue liner can be connected may be arranged to be located downstream of where the wall first divides a space in a chimney or chimney pot into the flue gas and the ventilation flow paths.
  • downstream and upstream means relative to the flow of flue gases. It may be desirable to separate the first outlet from the second outlet to avoid flue gases entering the space between the flue liner and the chimney and to allow the second outlet to be designed for the specific requirements for venting the space. For example, it may be desirable that the second outlet is arranged to avoid the ingress of rain water to the space between the flue liner and the chimney through the second outlet. More specifically, the attachment may be arranged such that, in use, the second outlet opens horizontally or/and downwardly.
  • the second outlet may be a hole in the wall, the hole located upstream of the support surface.
  • the chimney attachment may be a chimney pot wherein the flue liner is arranged to be connected to the inner surface of the chimney pot downstream of a hole in the chimney pot that provides the second outlet.
  • the chimney attachment is arranged to be retro-fitted to a chimney pot, (rather than being the chimney pot itself).
  • the chimney attachment comprises a frame attachable to the chimney or a chimney pot, the frame comprising a support ring providing the support for connecting to the flue liner, the support ring connectable to the chimney such that there is a gap between a wall of the chimney and at least a portion of the support ring, the gap leading to the second outlet to vent gases in the space to atmosphere.
  • the second outlet may be provided at at least two, three and preferably four or more spaced apart locations around the terminal attachment. Preferably, the second outlet extends continuously around a substantial, and preferably, all of a circumference of the chimney attachment. It will be understood that "a substantial circumference” may mean at least a quarter and more preferably, at least a half of the circumference.
  • This construction of the chimney attachment may mean that the ventilation provided by the attachment is not directional and provides ventilation in substantially all radial directions. This provides the advantage that a fitter does not need to consider wind direction or other factors since the chimney attachment or terminal generally has no preferred orientation about its longitudinal axis.
  • the attachment may provide a support surface for chimney-top devices or ornaments such as rain caps, aerials or weather vanes.
  • the attachment may comprise a rain cap configured to prevent or at least reduce the ingress of rain into the chimney without obstructing the or each outlet.
  • the rain cap may be provided with the attachment and attachable thereto.
  • the rain cap may be permanently connected to or integrally formed with the attachment. The provision of a rain cap may improve the aesthetic appearance of a given chimney.
  • the attachment may comprise a spacing member and a pot hanger, wherein, in use, the spacing member is located or locatable on top of a chimney or a chimney pot and between the chimney or the chimney pot and the pot hanger, wherein the spacing member is shaped and dimensioned such that, in use, the second outlet is defined at least partially by the spacing member.
  • the second outlet may be defined by the spacing member or by a combination of the spacing member and the chimney pot or the chimney or by a combination of the spacing member and the pot hanger.
  • the spacing member and the pot hanger may be provided as separate components.
  • the spacing member and the pot hanger may be integrally formed or permanently joined, e.g. welded, together.
  • the spacing member may comprise a flange or a washer.
  • the spacing member may be made from a metal, e.g. stainless steel.
  • the spacing member may comprise a Belleville washer or an at least partially corrugated washer.
  • a suitable corrugated washer may be manufactured from a flat washer using a crimping machine.
  • a method of installing a flue liner into a chimney comprising fitting a chimney attachment onto and/or into a chimney or a chimney pot and attaching a flue liner to the chimney attachment.
  • the chimney attachment may comprise at least one outlet.
  • the flue liner may be connected to the chimney attachment such that the at least one outlet is in gaseous communication with the flue liner for venting flue gases to atmosphere and in gaseous communication with the space between the flue liner and the chimney to vent gases in the space to atmosphere.
  • the flue liner may comprise a flexible metal flue liner.
  • the flue liner may be constructed from stainless steel.
  • the attachment may constitute a primary support for the flue liner within the chimney.
  • the attachment may bear substantially the full weight of the flue liner.
  • the attachment may constitute the only support for the flue liner within the chimney, i.e. the flue liner may not be attached or connected to the wall of the chimney by any other means at any other point.
  • the attachment may be attached to a top end of the flue liner. The flue liner may hang or be suspended from the attachment.
  • At least one outlet may comprise a first outlet and a second outlet, wherein the flue liner is attached to the chimney attachment such that the first outlet is in gaseous communication with the flue liner for venting flue gases to atmosphere and the second outlet is in gaseous communication with the space between the flue liner and the chimney to vent gases in the space to atmosphere.
  • the method may comprise fitting the chimney attachment to the top of a chimney pot.
  • the method may comprise not drilling a ventilation hole or fitting ventilation bricks in a chimney stack of the chimney.
  • the method may comprise fitting a rain cap to the chimney attachment.
  • the chimney attachment may comprise a rain cap.
  • a chimney having a flue liner therein and a chimney attachment, the flue liner and chimney defining a space therebetween, the chimney attachment connected to the flue liner to provide a first outlet in gaseous communication with the flue liner for venting flue gases to atmosphere and a second outlet in gaseous communication with the space between the flue liner and the chimney to vent gases in the space to atmosphere.
  • the chimney attachment of the invention can be used with chimneys that may or may not be provided with a chimney pot. Therefore, references to the chimney attachment being configured and used in relation to a chimney pot can also be read as being configured and used in relation to a chimney and vice versa.
  • a chimney 30 is provided with a flue liner 10 and a chimney pot 20. It is normal practice to take the liner 10 to the top of the chimney pot 20. The space between the liner 10 and the chimney 30 may be loose filled with a material such as Vermiculite or perlite insulation. Typically the liner 10 is a flexible metal liner, for example, the liner may be constructed from stainless steel. Providing a seal between the chimney pot 20 and the liner 10 can be problematic. Usually the seal is provided by hard cement mortar, however, this generally does not seal well with a metal liners because such liners expand and contract as they heat up and cool down. Flexible sealants may be used but these usually do not tolerate the high temperatures present when the chimney is in operation and these sealants can degrade.
  • FIG 2 illustrates a similar chimney and liner system to that shown in Figure 1 but in this case a conventional seal 40 is present to provide a seal between the liner 10 and pot 20 (such seals 40 are often referred to as "pot-hanger" seals).
  • a flexible sealant 42 can be used to prevent rain entering the chimney between the liner 10 and the pot 20.
  • a vent 50 may be provided in the chimney 30 by the fitment of an air brick ventilation component or by the drilling of holes, according to the practice of the tradesperson installing the pot-hanger seal 40.
  • FIG. 3 illustrates a chimney and liner system which has been provided with a chimney attachment 100 in accordance with one particular embodiment of the invention.
  • the chimney attachment 100 provides a first, central outlet 114 for venting flue gases that travel up flue liner 10 and a channel 110 for venting fumes from the space 15 between the flue liner 10 and the chimney pot 20 through a second outlet 112. That is, the chimney attachment 100 defines a conduit that provides flow communication from the space 15 between the flue liner 10 and the wall of the chimney pot 20 to the second outlet 112.
  • the curved arrows shown in Figure 3 illustrate the flow of gases vented from the space 15. It can be seen that the fumes are vented away from the opening of the flue so that the fumes do not travel down the flue into the building.
  • FIG 4 is a cross-sectional view of the chimney attachment 100 fitted to the top of a flue.
  • the chimney attachment 100 is a frame comprising an outer wall 140 and an inner wall 150. These walls 140, 150 at least in part, define a ventilation channel 110 that acts as a vent for fumes from the space 15 or region/volume that is present between the chimney/chimney pot 20 and the flue liner 10.
  • the channel 110 provides flow communication between the space 15 outside the flue liner 10 to the outside wall of the chimney/chimney pot 20 thereby directing fumes away from the inside of the flue.
  • the flow of the fumes is illustrated by curly arrows in Figure 4 .
  • a chimney pot may or may not be provided on the chimney so that the chimney attachment 100 can vent to the outside of a chimney pot (if present) or to the outside of the chimney itself.
  • top wall 120 that joins with the inner 150 and outer walls 140 to form an open box section that provides the venting channel 110.
  • a further radial inner wall 145 having an L-section defines the radial inner extent of the ventilation channel 110.
  • This radial inner wall may be attached to the walls 140, 150, by appropriate bridges (not shown), the bridges having gaps therein to allow fumes to flow to the outlet 112.
  • bridges not shown
  • various geometries can be used to provide a venting channel 110 of which some do not have a top wall 120.
  • the inner 150 and outer 140 walls take the form of co-axial walls that define a cylindrical space to form the venting channel 110.
  • the walls 150, 140 in this example take the form of concentric rings however other shapes could be used and the term "cylindrical" is to be taken in its broadest sense in which a cylinder of circular cross-section is only one embodiment.
  • the chimney, chimney pot and/or liner may take a form which has a substantially rectangular cross-section or cross-section of some other polygon (regular or irregular).
  • the outer or inner surface of wall 150 provides a support surface for attaching to the top of flue liner 10 to support the liner 10 in the chimney 20.
  • This support surface is provided downstream of a point 155 where the wall 150 first divides a space in a chimney or chimney pot into the central outlet 114 and ventilation channel 110 (ie "first" in the sense of the first instance of the dividing wall 150 in the direction of travel of the flue gases).
  • the flue liner 10 when the flue liner 10 is connected to the support surface, the flue liner 10 separates the outlets 114, 112, with the first outlet 114 in gaseous communication with the flue liner 10 and the second outlet 112 in gaseous communication with the space 15 between the flue liner 10 and the chimney 20.
  • the top wall 120 of the chimney attachment 100 may have a step 160 as can be seen in Figure 4 .
  • This step 160 may be provided so that, in cases when the liner 10 protrudes above the top of the chimney pot 20, the ventilating channel 110 is maintained, and the ingress of driving rain is reduced.
  • FIG 5 is a perspective view of the chimney attachment 100 illustrated in Figure 4 in isolation from the flue.
  • the chimney attachment 100 illustrated in Figure 5 has support tabs 130 which can be incorporated into the chimney attachment 100 for fixing the chimney attachment 100 to the chimney pot 20.
  • the support tabs 130 may be an integral part of the body of the chimney attachment 100 or they may be fixed to the chimney attachment 100.
  • the tabs 130 may be composed of a resilient material that can be biased to provide a gripping force on the chimney pot 20. The gripping force may act radially inwardly on the outer surface of the pot 20 or it may act radially outwardly on the inner surface of the pot, or tabs 130 may be provided that act in both of these ways.
  • the support tabs 130 provide the double function of supporting the chimney attachment 100 on the chimney pot while providing a passage to enable ventilation.
  • the chimney attachment 100 can in fact be fixed to the flue in many different ways, for example by the use of a clamp band or fixing screws. Instead of using a fixing means to fix the chimney attachment 100 to the outside of the chimney pot 20 a fixing means could also be used to fix the chimney attachment 100 to the flue liner 10.
  • the fixing means has the function of supporting the attachment on the chimney pot 20 and spacing the outer wall 140 of the attachment 100 away from the pot 20 so as to provide the venting channel 110.
  • the venting channel 110 will therefore run from the inner surface of the pot to the atmosphere on the outer side of the pot and the venting will be directed down the outside surface of the pot.
  • Figure 6 is a cross-sectional view of a further embodiment of the chimney attachment 100 fitted to a flue.
  • the inner 140 and outer 150 walls form a substantially open triangular section that acts as the venting channel 120. Therefore, the geometry of the terminal 100 is such that it does not have a top wall 120.
  • Figure 7 is a cross-sectional view of one side of a chimney attachment 100 according to another embodiment of the invention.
  • the inner 150 and outer 140 walls have an L-shaped cross-section to form the venting channel 110.
  • Figure 8 is a cross-sectional view of one side of a chimney attachment 100 according to a further embodiment of the invention.
  • the inner 150 and outer 140 walls are different sections of the same curved structure.
  • a fixing means 170 is shown fixing the terminal 100 to the flu liner 10, however, the fixings could act on the chimney or chimney pot 20 instead of, or as well as, on the flu liner 10.
  • the chimney attachment 100 is of a design that can be retro-fitted to a chimney 20 and flue liner 10.
