Technical Information

    Chimney Flexible Flue Liner (Type: 316)

    (See notes below for guidance on installing your flexible flue liner.)

    This 316 flex liner for wood and multifuel burning stoves is HETAS approved and manufactured in the UK from steel used to line both the inner and outer tube and is suitable for Solid fuel use. It is tested to (Designation No.) EN1856-2 T600 N1 D V3 L50012 G standards.

    This liner is double skinned with a smooth inner tube and for efficient delivery purposes the flex liner is sealed in plastic and wound in a spiral.

    The liner is sold by the meter (simply choose your length by entering the quantity required in the box above). Select the diameter of the liner from the drop down box above.

    When do you need to use a 316 or 904L chimney liner?

    • HETAS always recommend you line your chimney when installing a wood burning stove to ensure safe operation of your system
    • If the inside of your chimney breast has deteriorated such that there would be the possibility of carbon monoxide leaking into the room if not using a line
    • To Improve energy efficiency considerably especially if wrapping the liner in Flexwrap
    • Incorporating a chimney Register Plate (also known as a Closure Plate) which prevents particles from falling into the fireplace and onto the stove and providing a platform to place insulated material (such as Vermiculite) to improve efficiency even further.

    Note: Gas appliances use a single walled liner and therefore the 316 and 904L would be suitable. Conversely the single walled liner would be potentially dangerous to be used for all other appliances which burn solid fuels.

    What is the difference between 316 and 904L?

    The 904L flex liner is made from a higher quality and harder wearing steel than the 316; the 904L liner when exposed to elements and corrosive exhaust gasses will take considerably longer to present any rust or corrosion. Manufacturers will often recommend the 904L if burning a range of fuels including coal and smokeless fuels. Tip; do not burn contaminated wood which has been covered in chemicals or paint or use wet wood as this will increase the corrosion rate.

    The 316 Liner comes with a 10 year guarantee and the 904L with a 20 year guarantee against any manufacturing defects.

     

    Notes for Installation:

    (For customers intending to connect flex liner to twin walled flue pipe – refer to alternative notes on this type of installation (for example, Adapter, Console Plate)

    To install a flex liner you will need the following components:

    Flex Liner (316 or 904L) – the width of the liner is normally stated in inches.  Building Regulations require all liners (except for those used with DEFRA approved stoves) to be a minimum of 6” in diameter (DEFRA stoves can be 5” upwards).

    If you do not have a chimney pot you will require these items: Top Plate & Top Insert Sleeve, Top Clamp, Rain Cap or Pot Hanger (known collectively as ‘Top Fixings’). We do supply KITS which incorporate all the fixings and/or pot hanger required for the installation – these kits can also work out slightly cheaper than purchasing all the items separately.

    If you do have a chimney pot then you will just need a Hanging Cowl which satisfies the function of all the Top Fixings.

    Also needed or optional:

    Adapter from Flue Pipe to Flex Liner (required)
    Chimney Notice Plate (required by law)
    High Temperature Sealant & Fire Cement (required)
    Nose Cone (optional but very useful)
    Register {Closure} Plate (optional but is normally used)

    An Assistant – minimum two person job

    Obviously a means by which to get safely onto the roof of the property.

    Assemble the tools you will need together:

    Safety Glasses                   Safety Gloves
    Tape Measure                    Stanley Knife (or equivalent)
    Screwdrivers                      A strong hacksaw can be used to cut the {length of} liner to size
    Power Drill                         Disc Cutter/Grinder if incorporating a Register Plate

    How much flex liner should I purchase?

    Identify the distance between the connection from the adapter attached to your enamel or stainless steel flue pipe and the exit point as it travels out of the top of the chimney. Always err on the site of caution and add a little bit extra to the length measured – you can cut the liner down to size, but you cannot attach more liner to an existing liner. Under no circumstances, attach the liner directly to the top of the stove.

    Tips for identifying the length of liner:

    • Measure floor to ceiling in every room, including any loft space and add on a metre for the chimney and/or;
    • Stand at the side of the property and measure the height of one brick and count the number of bricks going all the way to the top of the chimney (multiply the height of the brick by the number of bricks counted).

    Unwrap the liner on a flat surface – careful not to puncture it.

    The following relates to connecting the liner to a hanging cowl or top fixings.

    Connect the top of the liner (it should be marked as to which end is the top – see note below *1) to the Top Fixings or Hanging Cowl *2 - then drop the liner down the chimney.  You can use the nose cone to guide the liner down the chimney breast *3. You may want to improve the insulation of the liner by using Flexwrap – if so attach this to the liner before dropping the liner down the chimney.

    *1  If the top of the liner is not indicated clearly, place a finger down either end of the liner being careful as the ends of the liner can be quite sharp. Slide your finger down the inside of the liner approximately 10 to 15cm. If the liner feels smooth to touch when you run your finger down inside the liner, then that end of the liner is the TOP end. However, if you can feel a distinct ridge or groove, then that is the BOTTOM end of the liner.

    *2  If you do not have a chimney pot, you will need to purchase the Top Fixings (kits are available for this purpose). A Hanging Cowl can only be used if you have an existing chimney pot or add a chimney pot to your existing stack.

    *3  If using a Nose Cone (recommended): Place some string into the hole at the base of the nose cone and tie a strong knot so that the string does not slip out of the hole when pulled. Attach a small but relatively heavy object (a tea spoon would do) and lower it with the string down the chimney. The nose cone attaches temporarily to the bottom of the liner and thus you can carefully pull the liner down the chimney with your assistant feeding the liner down from the top of the chimney.

    Once at the bottom of the chimney, the liner should be attached to the adapter which in turn is attached to your black enamelled or stainless steel flue pipe, rising out of the stove.

    Place some high temperature sealant around the edge of the connection between the liner and the adapter. Sealant must be rated to a minimum of 1250 degrees C.

    Why use a Register Plate?

    • To help secure the flue pipe in place as it travels up into the chimney stack
    • To close off the chimney stack to help prevent any loose objects from falling onto the stove and smoke returning into the room from the chimney
    • To allow insulation material (eg vermiculite) to be dropped down into the chimney stack to reduce heat loss from the room

    If using a register plate, you must remember that the adapter (the connection from the liner to the flue pipe) goes above the plate and therefore the plate must initially be lowered down over the pipe (rising up from the stove) before connecting the adapter to the end of the flue pipe and liner. Therefore, place the chimney register plate over the pipe and down towards the stove to allow you to fit a suitable adapter to connect the flue pipe to the flue liner (make sure you don’t scratch the flue pipe or stove when resting the plate on top). After completing the attachment to the adapter, lift the register plate up the flue pipe to the steel frame* and connect. Use high temperature sealant or fire cement around the sides of the flue pipe at the location at which it travels through the hole in the register plate.

    * Steel Frame: you should already have screwed this into place in the location you have chosen ready to raise and attach the plate to it.

    On the roof, complete the Top Fixings (or hanging cowl) and secure with weather proof sealant. However, if using insulation such as vermiculite, drop this down onto the register plate before securing the Top Fixings (or Hanging cowl). The Hanging Cowl has straps which connect directly to the chimney pot and therefore no sealant is required at the section. The Top Fixings will need to be cemented in place.

    Sit back and relax in the knowledge that in your lifetime, you probably should only ever have to do this once!

    Delivery

    Shipping Times

    The estimated shipping time of each product is displayed on the product page; where there is a next day shipping option available on a product you can select this option at checkout, usually for a small extra shipping charge. Some products are shipped direct from the manufacturer and so have a longer lead time; when one of these products is added to your order next day shipping will not be available as an option. If you would like to select a faster shipping service, you can split the order, placing a separate order for only those products with faster shipping available.

    Shipping Costs

    We cannot provide a shipping cost per product as the costs can vary depending on your postcode and the mix of products that you add to your basket. For this reason, to get an accurate shipping cost you can view your basket by clicking the text showing the number of items and total price of your order at the top right of the website. At the bottom of the basket page there is a shipping cost section, simply type in your postcode to get a list of shipping options and costs for all the products in your basket. You do not need to create an account or log in to get this information.

    Multiple Items

    Where multiple items are being purchased in the same order, we make an effort to limit the number of deliveries to a minimum but in some cases you may receive more than one delivery. For instance if you order flue liner this is delivered straight from the manufacturer and may arrive on a different day than other items in your order. You will receive email updates letting you know how your order is being delivered.

    Dispatch Time

    For standard deliveries dispatch time might be a few working days but should arrive within the time period stated on the product page. For next day deliveries we dispatch the same day if your order is placed by 1pm on a working day (Monday-Friday). Orders placed at a weekend are processed on the following Monday. Delivery times stated are working days and do not include weekends.

    Stove and Pallet Deliveries

    Stove deliveries and large orders will come on a pallet delivery service. If you select standard delivery this will take 3-5 working days and we are unfortunately unable to tell you the day that delivery will be made. We always pass on your contact details to the pallet couriers who will contact you if there is an issue with delivery. If you would like to organise a delivery for a named day, including next day orders you must select the next day upgrade at checkout, but it is best to phone us to place these orders. Standard deliveries are classed as curb side only and drivers may not always be able to help you into your home with the stove. If you require a 2 man, white glove delivery you can select this at checkout for certain stoves and this service guarantees delivery into a chosen room. The 2 man delivery service is not a named day delivery at the point of purchase, however they will contact you in advance of the delivery to arrange a suitable day and time and also call you half an hour prior to the delivery.
