A flue kit is usually comprised of the following products:

Stove Pipe

Stove pipe is the short length of pipe that comes out the top of the appliance and connect to the chimney stack (via the register plate).
Constructed from vitreous enamel, we supply in matt black or stainless steel finish.

Flexible Flue Liner

Flexible flue liner is the cylindrical steel tubing used to line the brick chimney, and runs the length of the chimney stack from stove pipe up to chimney cowl.

It's sold by the metre, so it's advisable to know the length of your chimney stack before ordering.

Stove Pipe to Flue Liner Adaptor

Stove pipe to flue liner adaptor enables the flue liner to connect to the stove pipe.

Nose Cone

A nose cone helps in pulling the flexible liner
through the chimney during installation, keeping it from getting snagged.

Register Plate

A register plate closes off the chimney stack at the bottom , preventing debris falling down your chimney.

Cowl

Chimney cowls come in many different types, with the main purposes of preventing debris and animals getting into the chimney at the external opening,
and helping the chimney draw better to ensure proper function of your stove.

Fire Cement

Fire cement is a putty like jointing material capable of withstanding heat up to 1250 degrees.

Used seal the joints of different elements of your installation.

Will I need any other products?

There are many other items you may need, depending on the details of your project, that are not usually included in flue kits.

These may include:

• Vermiculite insulation to backfill any gaps between the flue liner and the chimney stack.
• Flue damper to control the draw from your chimney to slow down rate of burning
• Stove accessories from companion sets, to log bcukets, baskets and shovels, we stock a full range of accessories.
• Chimney notice plate Under building regulations, it's a legal requirement to fix a notice plate close to your appliance.
• Carbon monoxide alarm 

Chimney Flue Kit FAQ

What flue do I need for a log burner?

Building Regulations dictate that the minimum flue diameter for stoves up to 20kW burning smokeless fuel should be a minimum 5inch / 125mm diameter.
For stoves up to 30kW and burning any fuel the diameter should be a minimum 6inch / 150mm diameter.  Defra exempt stoves with a 125mm outlet are able to use a 5inch /125mm diameter flue.

How do you fit a wood burner flue?

Flexible flue is first either pulled up the chimney stack or dropped down from the top (for this a nose cone is extremely useful). Connections are then made to the register plate at the bottom and chimney cowl at the top. For more information see our flexible flue liner installation guide 

Can I install a log burner myself?

It is strongly recommended that you get a HETAS approved tradesman to install and connect your log burner. The exhaust gases from stoves can be dangerous, due to carbon monoxide, if they leak out into the room, not to mention any risk of fire, so it really is advisable to get it done by a specialist.

What's the difference between 316 and 904 flue liner?

The installation of a flue for wood or multifuel stoves requires a class 1 liner with an inner of either 904 or 316 grade stainless steel.

But what is the difference?

The difference between 904 & 316 is the thickness of the layers within the steel. 316 liner is suitable for most domestic wood burning stoves. However for multifuel appliances, 904 liner should be used as it is a higher grade liner.

This is due to a higher production of acidic condensates when burning smokeless fuels.

How long will a flexible flue liner last?

This will obviously depend on where you obtain your liner, but our own Ultraflex flexible liner, manufactured by us in the UK, has the following minimum life expectancies:
Our Ultraflex 316 grade flue liner (suitable for burning dried seasoned wood, gas & oil) is guaranteed for 20 years.

Our Ultraflex 904 grade liner (suitable for burning dried seasoned wood, gas & oil) is guaranteed
for 35 years.

How often should you replace your chimney liner?

On average, the lifespan of a chimney liner is around 20 years , after which time you will probably need to get the entire liner replaced to ensure it's still up to the job and not a serious fire risk. If you opt for our Ultraflex 904 grade, the minimum life expectancy is 35 years.
