We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember The Natural Philosopher
saying something like:


Well i think that you should call Corgi for advise regards your chimney
liner..Any gas engineer will tell you a standard brick chimney DOES NOT
required a liner so long as it is in good condition ,,,meets the
correct sizes,,,and passes the flue flow test....there are regulations
that confuse non gas trained people///ive serviced tens of thousands of
gas fires WITHOUT liners....If the smoke test proves a faulty Flue then
i advise that a flue liner is required..

Thius is completely WRONG

Brick chimneys MUST be lined with

- socketed clay liners or
- imperforate clay pipes or
- socketed cement pipes. or
- fixed metal tubes or
= felxible liners for chimneys already equipped or built before 1966

This is a Building Regulation.

You mean....

Gasman is talking out of his arse?

Must be where his nick comes from.

To put things into context -

New chimneys must be built to meet building regs - no-one is arguing against
that

Old chimneys were not and may have worked just fine for many years. Fitting
a gas fire to a preused solid fuel flue which is swept prior to the
installation, inspected in good order and passes flue flow and after
installation passes no spillage test is permissible. If the old flue is not
in good order or does not pass the tests then a liner will be required.
