Is this 904 liner HETAS compliant?

Yes. The 904 stainless steel liner and components are CE-marked and HETAS compliant when installed per the manual and UK Building Regulations.

When should I choose 904 instead of 316?

904 grade offers thicker steel and higher corrosion resistance, recommended for coal/smokeless fuels or where condensation/acidic flue gases are likely.

How is a 904 flexible liner installed?

Fit from the top with a nose cone and rope. Ensure the arrows on the liner point upward in the flue-gas flow direction. Connect with the adapter and secure with a rain cap/pot hanger.

Does the kit include everything I need?

The kit includes the 904 liner (per metre), rain cap/pot hanger, nose cone and adapter. Extra parts may be required depending on your chimney (register plate, fire cement, etc.).

What diameter of flue do you need (mm)?
WOODSTOVES & MULTIFUEL STOVES: The flue legally needs to be a minimum of 6" (150mm) in diameter if you are burning wood or coal. Unless when you install a DEFRA approved stove with a 5" flue outlet, in which case you can use a 5" liner (125mm).
What is the required length for the liner?

If your flue liner is not long enough for your installation there will undoubtedly be delays and disappointment (plus the additional cost of a correctly sized flue liner). Adding an extra metre (or two) - will help ensure your installation goes ahead without delay.

We also add the " Adapter stove pipe to flexible liner" to the shopping list. Plus a Nose Cone.
Choose the (necessary) connecting stove pipes

You can not connect the flexible liner directly to the stove. You need at least 500mm of stove pipes first.

At 1mm steel thickness the stovepipe can be easily cut to the required size using fine-grain grinding disks. Do not cut the small side of the pipe!

The most common wood stove position involves placing the rear half of the stove within the chimney cavity, while the front half protrudes out into the living space. In this case, it's necessary to connect your stove to the flue liner using two 'elbows' from the top of the stove - so in simple terms, if you can’t put the stove pipe directly up and out of the chimney, then you need to create some 45 degree corners in order for the liner to go backwards (into the chimney cavity) and then up out of the chimney.
What kind of finishing on the top is needed?

The choice of the end parts depends on whether or not there is (still) a pot on top of the chimney.

Pot still present: Pot hanger Raincap

For when there is still a pot on the roof. To suspend flue liner at the chimney pot.

No more pot: Fixing plate and Clamp

When there is no more pot on top the chinmey you also need a fixing plate on top of the chimney. (see complete explanation below)
