Gas / Oil Flue Liner

1. Always work safely and in accordance with current health and safety requirements.
2. Take sensible precautions when working at high levels by using scaffolding, access tower etc and always wear suitable protective clothing.
3. The ends of chimney liners are sharp - wear gloves.
4. Soot is acidic and can irritate you skin, eyes and lungs - wear a dust mask and goggles.

Survey & Preparation Work

1. Sweep the chimney thoroughly to remove all soot deposits, tar and deposits - otherwise these can corrode the chimney liner once fitted.
2. Check that the chimney is structurally sound and that all external surfaces are wind and watertight. The structure should be constructed of solid masonry of at least 100mm (4") thickness.
3. Remove the chimney pot, any damper plates, or other obstructions that will hinder the installation of the chimney liner. If there are bends or obstructions in the length of the flue the wall will require opening to ensure proper access and installation. 
4. Determine the correct diameter of chimney liner required for the application. 
5. Draw a sample 1 metre length of the correct diameter liner through the chimney to ensure that it will pass through any restrictions and changes of direction.
6. Use only a single length of chimney liner - not short lengths jointed together.

Installation and Connection

1. If the flue liner has direction arrows, then take notice of them. It is important that the flue liner should be installed so that the arrows point up the chimney. This will allow any condensation to drain downwards over the internal joint. Not all gas / oil flue liners have arrows, however. Where there are no arrows, the flue liner can be installed either way up.
2. Attach a nose cone with a draw rope to what will be the bottom end of the chimney liner.
3. Installation is a job for two.
4. First installer drops the draw rope down the flue.
5. Second installer takes the rope at the bottom of the chimney and carefully pulls the chimney liner downwards whilst......
6. the first installer guides the chimney liner over the top of the chimney and into the flue, taking care to avoid letting the chimney liner bend too sharply (i.e. less than three times the diameter of the chimney liner) or scrape over any sharp corner etc.
7. Once the chimney liner is pulled all the way through the flue, connect the base of the chimney liner to the appropriate adaptor using stainless steel self tapping screws and seal with fire cement or Fortafix Ceramix.
8. Fit the clamp plate.
9. Flaunch with a suitable mortar or fit a suitable chimney pot.
