Vendor: Flexi Flue Pipes

If you are installing a Wood Burning or Multi-fuel Stove in your home it is always advisable to install a Flue Liner. A Flue Liner will not only help to provide a better draw for your chimney, it will provides safe passage so harmful fumes will not enter the room. At BPM SUPPLIES we source stainless steel twin walled flexible flue liner from 100mm (for condensing oil boilers) to 300mm. We can supply you with per-cut lengths of flue liner (usually 6m for Bungalows or 9m for Two Storey houses) or specific lengths for those with particular requirements. We also supply the Flue Adapter, Plates and Cowls – all you will need when installing a stove. If you wish to install a flue liner for an open fire we also supply the fitting required to complete the job. For an open fire always use 7" or 8" chimney flue liner and for a stove always uses 5" or 6" flue liners. (Some of the bigger stoves for central heating may use 7" flue liner) 
If you have a build up of soot behind the crevices where your chimney liner is compromised cleaning will not remove this. The hidden soot can ignite, thus causing chimney fires. You should never burn wet timber as it leaves a tar on your liner which can ignite. Once you have had a chimney fire the chances are that the chimney liner has been compromised and repairs will have to take place. When using a damaged chimney with either a stove or open fire you run the risk of the seepage of fumes which could result in unhealthy or fatal amounts of Carbon Monoxide. When installing a wood burning appliance it is now part of building regulations to install a carbon monoxide detector. There is no substitute for a chimney not being in a full working order and a carbon monoxide detector is only a warning device. If you have recently had a chimney fire or if your chimney is more than 30 years old you would be best to reline using a stainless steel flexible flue liner. Our flexible flue liners are manufactured to BSES 150 9001 and tested to the EN1856 European Standard. These flue liners are guaranteed for 10 years upon correct installation but will last for longer if the correct fuels are used and it is swept on an annual basis. If you do believe you have a problem with your chimney please have a smoke test done.

Flue Liner should always be fitted from the top.

Make sure the arrows are pointing upwards (gas flow).

Secure a piece of string (at least the same length as the Flue Liner to the Nose Cone (order separately).

Now attach the Nose Cone onto the end of the Flue Liner, again making sure the arrows on the Flue Liner are pointing away from the Nose Cone in a upward direction so when the liner is installed the arrows will be pointing to the top of the chimney

Pull the liner down the chimney using the string and at the same time have someone at the top of the chimney feeding the Flue Liner down, once the Flue Liner is fitted remove the Nose Cone.


It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year.
