Flexible Liner - Installation
Before you start your installation of any of the Turner & Wilson flexible flue liners, Twinflex, Weldline or Triplelock please be aware that exposed edges are sharp. Protect yourself against cuts by applying tape to both ends. Also try not to over coil the liner.
Thoroughly sweep the chimney before installation.
Brickwork must be sound, dry and free from defect. D.P.C., flashings etc. should be thoroughly checked and faults corrected before installation.
It is important to ensure that the lining will pass down the chimney easily. Shine and light down the flue to ensure there are no obstructions. If in doubt, use a short test piece with nose cones and cords on each end.
Liners below 250mm dia. should be in one piece. Use a nose cone with a draw cord and always pass the liner down the flue from the top. Liners should easily go down the flue.
If a lining becomes trapped it is due insufficient clearance:
· DO NOT continue the installation.
· DO NOT use excessive force.
· DO NOT attempt to 'twist' the lining by rotating the coiled end. The very high leverage this causes may result in a partial of the lining.
Flexible Flue Liner Installation - On The Roof
There must be an adequate air supply. Ensure that air intakes are not contaminated by any chemical fumes.
Fix clamp plate to cap the chimney and clamp the liner. Trim the liner and place the terminal.
Finish by setting the terminal in a sand and cement parging.
Flexible Chimney Liner - Completing the Installation
For gas fires fit a collector box. These have a removable socket for ease of installation.
Free Standing boilers usually use Vitreous Enamel pipes for the short connection into the flue.
It is important to fit a condensation trap at the lowest point of the vertical liner.
Failure to to this will result in condensation problems.
