FlueCube – Installation Guide version 3.0.2

The construction consists of the two main components:

(a) Main Body(b) Base Cone with integral tube

- Secondary components:

(c) Size Adapter – Metric to imperial adapter sleeve(d) Long Straps – for securing to chimney pot or twin-walled flue(e) Short Straps – primarily for use when FlueCube is used as a suspending cowl(f) Pot Rests – these raise the FlueCube off the pot to let the chimney and pot breathe

- and fasteners:

(g) 4 x M6 Set Screws (Bolts) – For fixing Main Body to Base Cone(h) 4 x M6 Nuts – for Attaching Straps(i) 8 x M6 Lock Washers – for Screws and Nuts(j) 3 x No 10 (4.8mm) Self Drilling Screw – for secondary fixing to flexible liner(k) 2 x Jubilee Clips – for fixing FlueCube to flexible liner, and to chimney pot or twin-walled flue

The FlueCube is designed to be compatible with standard types of chimney flues and scenarios, including those listed below, and comes complete with standard hardware necessary for fitting:

1. To a chimney pot with an existing flexible liner already independently suspended2. As a suspending cowl, whereas the FlueCube suspends a flexible liner 3. On to a twin-walled insulated flueNote: The FlueCube can be installed on an existing, or new flue of compatible size*, with, or without a chimney pot. If no pot is used, the FlueCube requires to be slightly raised off a chimney to keep vents open. It is important to securely mount it also, using straps provided, and or alternative fixings.Additional weather flashing may be required when used without a pot, or for square pots.*A flue should not be significantly reduced in diameter/flow, causing a bottleneck.Building regulations must be adhered to.

Fitting a FlueCube to a lined flue is similar The construction is modular to make fitting adaptable, and simpler. The FlueCube should be directly connected to a flue so it is sealed from the wood burning stove to the FlueCube inlet. High temperature sealant MUST be used on all connections.

Tools Required:• Cordless drill• 5/16” (or 8mm) hex socket and cordless drill arbor attachment• 10mm ring/open-ended or adjustable spanner• 10mm hex socket and cordless drill arbor attachment (Optional)• Caulking gun• Drill bits & Rivet gun (optional)• Small spirit level (optional)

Consumables:• High Temperature Sealant (600 C +). See example (l).

Note: The FlueCube can become very hot, and standard heat-resistant silicone based products will break down and fail, and are inappropriate. It is essential to have a good seal right from the wood stove to the inlet of the Flue Cube. A product such as “HeatSeal” is rated at 1200 C and is therefore ideal.

• Stainless steel rivets (optional)

IMPORTANT: The FlueCube works by improving the draw (vacuum) on the flue and firebox. For this reason a good seal is essential from the firebox to the FlueCube inlet.

Installation to pot with existing independently suspended flexible liner:

This method is to be used on existing lined flues where the liner does not need to be supported by a cowl.It is the most likely installation process for when there is an existing flexible flue liner in place, with, or without an existing cowl.

At the chimney top:

1. Remove any existing cowl and ensure inside the end of the liner is clean and not bent.2. The existing liner needs to end within 70mm from the top of the pot.

If not, it will need extending to this level. Single wall flue is recommended.The connection needs to be safely secured, and sealed with the high temperature sealant.

3. Fold out at least one tab on the Size Adapter (c) to 90º (This prevents it dropping down inside the flue)• Check whether the adapter fits into the flexible liner or flue extension.– If not, the base cone tube should fit directly inside the flue liner/pipe. Check to be certain.The adapter should be used if it fits to ensure a good seal.

At ground level:

4. Selecting Straps and Pot Rests (d-f):• Secure the Long Straps (d) and Pot Rests (f) onto ALL 4 threaded studs inside the base cone (b), using the Lock Washers (i) and the Nuts (h). See figure 1.Note: The four Nuts (h) must be securely fastened and used with the Lock Washers (i).Pot Rests (f) are for pot and flue venting, and should be used – unless fitting to an already vented pot.

5. Loosely screw two Set Screws (Bolts) with Lock Washers into opposite sides of the Base Cone.See figure 1.

At the chimney top with any existing cowl removed:

6. If the Size Adapter (c) is to be used:i. Fold out the four tabs to right angles (this ensures that adapter doesn’t drop inside the flue)ii. Apply a heavy bead of sealant completely around the outside of it (about 2 ribs up)

See figure 2iii. Push into liner or extension. Enough sealant must be used to create a good lasting seal.

7. Apply sealant completely around the Base Cone tube (b) at a level that will sit within the flue liner – and Size Adapter (c), if used. About 50mm (2”) up from the bottom of the tube is ideal.See figure 1.

8. Slide the Base Cone tube (b) into the flue – and Size Adapter (c) if used, ensuring the Pot Rests sit against the chimney pot.

9. Turn the Base Cone (b) so the Set screws and other holes are in line with the building walls.10. Secure the Outer Straps (d) to the chimney pot using a Jubilee Clip (k).

The Jubilee Clip (k) should be as close to the FlueCube base as is possible. The position may be dependent on the pot design. Directly under a rib on a chimney pot is ideal for strength & looks.Note: It may be necessary to make final alignment adjustments once the Main Body (a) is in place to ensure the installation is straight in relation to the chimney and building.

Fitting the Main Body (a):

11. Sit the main body onto the Base Cone (b) so the slots sit onto the two M6 Set Screws (g) inserted earlier (Step 5). Take care that the Lock Washers (i) remain on the outside of the Main Body.

12. Screw remaining M6 Set Screws (g), each through a Lock Washer (i), into the two remaining holesin the base of the Main body (a), into the Base Cone (b).

13. Do any final positioning by moving the Outer Straps (d), and tighten the Jubilee Clip. (k)14. Fold up and trim any excess on the Outer Straps (d) as necessary to make the installation neat.15. Tighten all the screws and bolts securely.

Fitting to an existing independently suspended flexible liner is complete.

Installation to Suspend a Flexible Liner from Chimney Pot (as Pot Hanger):

Preparation:The following explains how to attach to a new liner. Attaching to an existing liner is technically possible but will be dependent on individual cases, and factors such as how much slack is in the length of the liner.• The liner will need to end up within 70mm from the top of the pot.

1. Fold out at least one tab on the Size Adapter (c) to 90º See figure 2.The Tab/s prevent it dropping down inside the flue.• Check whether the adapter fits into the flexible liner or flue extension. If so, fold out all tabs.– If not, the Base Cone tube (b) should fit directly inside the liner. Check to be certain.The adapter should be used if it fits to ensure a good seal and to avoid damaging the liner.

2. Selecting Straps and Pot Rests (d-f):• Secure both the Long and Short Straps (d & e) and Pot Rests (f) onto each of the 4 threaded studs inside the base cone (b), using the Lock Washers (i) and the Nuts (h). See figure 1.Note: The four Nuts (h) must be securely fastened and used with the Lock Washers (i).Pot Rests (f) are for pot and flue venting, and should be used – unless fitting to an already vented pot.

3. Thread one Jubilee Clip (k) through loops in Short Straps (e), and do up loosely.4. Loosely screw two Set Screws with Lock Washers into opposite sides of the Base Cone.

See figure 1.

At the chimney top with liner protruding– Liner either not connected at stove, and/or temporarily supported at chimney top.5. If the Size Adapter (c) is to be used:

i. Apply a heavy bead of sealant completely around the outside of it (about 2 ribs up)See figure 2

ii. Push into liner. Enough sealant must be used to create a good lasting seal.6. Apply sealant completely around the Base Cone tube (b) at a level that will sit within the flue

liner – and Size Adapter (c), if used. About 50mm (2”) up from the bottom of the tube is ideal.See figure 2

7. Slide the Base Cone tube (b) into the flue liner – and adapter, if used. It is recommended that the liner is pushed on to only leave about 50 – 60mm of Base Cone (b) tube showing. See figure 3.

8. Tighten the Jubilee Clip (k) threaded through loops on to liner , adapter - if used, and FlueCube.See figure 3.

9. It is recommended that the Self-drilling Screws (j) are used to create a secondary fixing to support the Liner. At least two (on opposite sides) should be used. Do this by drilling/screwing them through the holes in the Short Straps (e), through the liner and into the Base Cone tube (b), and tighten. Stainless steel pot rivets can be used as an alternative to the screws. See figure 3.

10. Lower the flexible liner into the chimney carefully, until the FlueCube Pot Rests (f) sit on the pot.11. Secure the Outer Straps (d) to the chimney pot using the second Jubilee Clip (k).

The Jubilee Clip (k) should be as close to the FlueCube base as is possible. The position may be dependent on the pot design. Directly under a rib on a chimney pot is ideal for strength & looks.Note: It may be necessary to make final alignment adjustments once the Main Body (a) is in place to ensure the installation is straight in relation to the chimney and building.

12. Turn the Base Cone (b) so the Set screws and other holes are in line with the building walls.Fitting the Main Body (a):

13. Sit the main body onto the Base Cone (b) so the slots sit onto the two M6 Set Screws (g) inserted earlier (Step 5). Take care that the Lock Washers (i) remain on the outside of the Main Body.

14. Screw remaining M6 Set Screws (g), each through a Lock Washer (i), into the two remaining holes in the base of the Main body (a), into the Base Cone (b).

15. Do any final positioning by moving the Outer Straps (d), and tighten the Jubilee Clip. (k)16. Fold up and trim any excess on the Outer Straps (d) as necessary to make the installation neat.17. Tighten all the screws and bolts securely.

Fitting as a suspending cowl is complete.

Installation on to Twin-walled Flue:

The existing flue typically comes through a roof, or is mounted externally to a wall. The FlueCube can be used in either situation.

Note: The base of the FlueCube works as a storm cone, so it is not necessary to add extra flashings to protect the wallof twin-walled flue. Additional flue flashing may be required if it is mounted through a roof for new installations.

At the chimney top:

1. Remove any existing cowl and ensure inside the end of the inner liner is clean and not bent.2. Fold out at least one tab on the Size Adapter (c) to 90º (This prevents it falling down the flue)

• Check whether the adapter fits into the inner flue wall.– If not, the base cone tube should fit directly inside the flue pipe. Check to be certain.The adapter should be used if it fits to ensure a good seal.As most twin-wall is metric the adapter may not be required.

At ground level:

3. Selecting Straps and Pot Rests (d-f):Only one set of Straps is required for twin-walled flue installations. Note: Only the long set are adjustable.i. Secure either the Long Straps (d), or Short Straps (e) onto each of the 4 threaded studs

inside the base cone (b), using the Lock Washers (i) and the Nuts (h). See figure 1.Note: The Nuts (h) must be securely fastened and used with theLock Washers (i).The Pot Rests (f) are not required. Note: Long Straps are shown in Figure 1

ii. If short straps are used the Jubilee Clip (k) may be threaded through the strap loops and done up loosely – although this is not essential at this stage.

4. Loosely screw two Set Screws (g) with Lock Washers (i) into opposite sides of the Base Cone.See figure 1.

At the chimney top with any existing cowl removed:

5. If the Size Adapter (c) is to be used:i. Fold out the four tabs to right angles (this prevents the adapter from falling down the flue)ii. Apply a heavy bead of sealant completely around the outside of it (about 2 ribs up)

See figure 2iii. Push into flue. Enough sealant must be used to create a good lasting seal.

6. Apply sealant completely around the Base Cone tube (b) at a level that will sit within the flue liner – and Size Adapter (c), if used. About 50mm (2”) up from the bottom of the tube is ideal.See figure 1.

7. Slide the Base Cone tube (b) into the flue, as above (Step 6). The 4 threaded studs are designed to rest on the outer liner of the twin-walled flue to allow for venting.

8. Turn the Base Cone (b) so the Set screws and other holes are in line with the building walls.9. Secure the Straps to the outer liner using a Jubilee Clip (k). Note: If Short Straps (e) were used this

may have been threaded through loops in step 3.The Jubilee Clip (k) should sit as close to the FlueCube base as is possible for looks.Note: It may be necessary to make final alignment adjustments once the Main Body (a) is in place to ensure the installation is straight in relation to the chimney and building.

Fitting the Main Body (a):

10. Sit the main body onto the Base Cone (b) so the slots sit onto the two M6 Set Screws (g) inserted earlier (Step 5). Take care that the Lock Washers (i) remain on the outside of the Main Body.

11. Screw remaining M6 Set Screws (g), each through a Lock Washer (i), into the two remaining holes in the base of the Main body (a), into the Base Cone (b).

12. Do any final positioning by moving the Straps, and tighten the Jubilee Clip. (k)13. Fold up and trim any excess on the Outer Straps (d) as necessary to make the installation neat.14. Tighten all the screws and bolts securely.

Fitting to a Twin-walled flue is complete.
