• The inner layer is smooth to discourage the build up of soot and other potentially corrosive
  residues and to encourage the unimpaired flow of flue gasses

  after installation it helps protect the inner layer from corrosion due to attack by residual
  deposits

User Instructions
Our Multi Fuel Chimney Liner is constructed using high grade, BS1449 quality assured stainless steel. With care and correct use it will provide many years of safe, and reliable service - But it is important that you read and follow these instructions fully.

• DO burn the correct fuel for the appliance

• DO burn "seasoned", dry wood - that is split logs which have been stacked for 12-24 months under cover outside allowing a free circulation of fresh air.

• DO NOT burn any of the following: Wet or "Green" wood, painted or treated timber, household refuse, petrochemical by-product coal substitute. These can create soot deposits and gasses which are toxic and will corrode the chimney liner.

• DO sweep the chimney at least twice a year, more often may be necessary depending upon the fuel and use. Instruct the chimney sweep that only a bristle brush of the correct diameter should be used on rods - not a ball and brush

• DO avoid chimney fires. The extreme temperatures involved can damage the liner.

• DO NOT allow fires to "slumber". This produces corrosive condensation in the flue and increases the chance of chimney fires. This is particularly important for closed appliances.
