USE OF FLEX TESTER KIT
The tester kit is an economical and convenient way of ensuring that the chimney stack is suitably sized and free from obstructions. Failure to check this prior to installation of the liner could lead to the warranty on the flex liner being invalidated if the liner is subsequently damaged due to snagging on an obstruction.
As long as the flex liner is intact, then it can continue to be re-used.
Yes, the the screw fit nose cones, which are provided with the tester kit can be used with a new length of TecnoFlex Plus. Alternatively the screw fit nose cones can be purchased separately from stockists.
The nose cones are specifically engineered to fit the pitch of TecnoFlex Plus only.
