WOOD 316 Grade Chimney Flue Liner - 175mm Diameter (35Z-180)

Our multi fuel chimney liner is CE Approved to BSEN 1856:2. It is a HETAS Approved product and is rated to 600°C

Our multi fuel chimney liner is manufactured using a single strip of raw material. This is rolled, seamed and manipulated in such a way that it forms both the outer corrugated skin, which has a high crush resistance, and an extremely smooth inner skin, which helps any condensates from forming on the liner. The smooth surface of the inner skin also allows for easy sweeping. The product has 2 convolutions between each seam.

Having been made from one strip of material, instead of two that are seamed together, means it is virtually impossible to unwind and can withstand prolonged high temperatures without distortion.

Our multi fuel chimney liner is available in the following diameters:
100mm, 125mm, 150mm, 180mm, 200mm

Before Installation
Inspect the interior and exterior of the chimney and ensure that any damaged external brickwork or cappings have remedial work done prior to installation. After you have inspected the chimney and made any necessary repairs, you should have the chimney swept by a qualified chimney sweep and remember to keep any certificates as you may need them later.

Installation
There are two methods of installation at the top of the stack that we recommend:

1. Remove the chimney pot and secure the liner with a clamp and plate
2. Do not remove the chimney pot and secure the liner using a pot hanging cowl (this method is not recommended in an exposed area)

Method (1) - Pot Removal
(a) Attach the draw-cord to the nose cone and use self-tapping screws OR strong tape to secure the nose cone to the end of the liner. Alternatively, use a screw-fix nose cone so to not damage the liner.

Lower the nose cone into the chimney from the top, gently pulling from below using the draw-cord (if necessary). When the lower end position has been determined, remove the cone.

(b) Remove the chimney pot and clear any cement and debris from the pot area.

(c) When the chimney liner is all the way through the flue, connect the base of the chimney liner to the appropriate adaptor using stainless steel screws and seal with fire cement, or use a screw-fix adaptor so as to not damage the liner.

(d) If you are insulating the chimney do this now (see Insulation).

(e) Cut the liner to the desired length, leaving about 100mm for the clamp to be secured, and insert the Protection Sleeve into the top of the liner.

(f) Place the Top Plate over the liner and secure the liner in place using the Top Clamp. The clamp should secure both the liner and the Protection Sleeve.

(g) Flaunch the Top Plate, Top Clamp and surrounding area with a suitable mortar and re-fit the chimney pot.

Method (2) - Not removing the Pot
(a) Attach the draw-cord to the nose cone and use self-tapping screws OR strong tape to secure the nose cone to the end of the liner. Alternatively, use a screw-fix nose cone so to not damage the liner.

Lower the nose cone into the chimney from the top, gently pulling from below using the draw-cord (if necessary). When the lower end position has been determined, remove the cone.

(b) When the chimney liner is all the way through the flue, connect the base of the chimney liner to the appropriate adaptor using stainless steel screws and seal with fire cement, or use a screw-fix adaptor so as to not damage the liner.

(c) Cut the liner to the desired length - this should be to the height of the chimney pot.

(d) Attach the Pot Hanger or Pot Hanging Cowl to the top of the liner - the bottom spigot is inserted into the top of the liner and the straps are then tightened around the liner to form a secure hold. If a screw-fix pot hanger is used make sure you screw the pot hanger on tightly to the flex.

(e) The Pot Hanger or Pot Hanging Cowl should now fit flush with the top of the chimney pot.

(f) If the Hanger has a strap on the outside secure this to the pot.

Insulation
We recommend insulation or back filling only on tall, large or exposed chimneys. Whilst not essential, an insulated flue should ensure maximum performance and minimum condensation in the lining.

To insulate the chimney either:
1. Use a loose fill granular insulating material such as Micafil; this should be mixed one part ordinary Portland cement to six parts Micafil.
2. Use Rockwool insulating tubes.

After installation
Fuels
Only fuels that are HETAS approved should be used. If you are burning wood, you must make sure the water moisture content is less than 20% and the wood has been seasoned for at least 12 months, otherwise this can lead to a buildup of creosote deposits which, in turn, could lead to a chimney fire.

We do not recommend slumbering your appliance overnight, especially with coal-based fuels, as this causes condensate to build up and acid corrosion.

Household rubbish or painted wood must not be burned!

Warranty
Our multi fuel chimney liner has a lifetime* product replacement warranty.

Providing the flexible flue liner has been installed correctly, only approved fuels have been used, and the flexible flue liner has been cleaned and maintained then the liner will last the lifetime of the appliance. If you change the appliance or have a chimney fire then the flue liner must be changed.

Maintenance
It is important that provision is made for inspecting and cleaning the flexible flue liner. If burning solid fuels the flexible flue liner should be swept at least twice a year by a qualified chimney sweep and a certificate given. Cleaning should only be carried using nylon brushes and rods.
