The liner is used to re-line your existing chimney, the liner should always be fitted from the top ,Before you start secure the NOSE cone (order separately) onto the end of the liner making sure the arrows on the liner are pointing away from the nose cone in a upward direction so when the liner is installed the arrows will be pointing to the top of the chimney, pull the liner down the chimney using a draw string which isn't supplied with the Nose cone at the same time have someone at the top of the chimney feeding the liner down, once the liner is fitted remove the nose cone.
Please Note : The Person at the top of the Chimney Should Be the One Pushing The Liner Down the Chimney with the Person on the Draw String Helping to Guide The Liner Around any Obstacles EG : Bricks in the Chimney)
