Andrew Hartley, a 37 year old registered gas fitter from Radstock, Somerset, had worked on the boiler at the Bath home of publishing tycoon and TED owner Chris Anderson in December 2010. Mr Anderson’s 24 year old daughter Zoe Anderson was found dead in the bathroom 12 days later.
Investigations revealed that a gas flue was not correctly connected to the turret elbow.
A jury found Mr Hartley guilty of manslaughter by a majority verdict of 10-2 following a two week trial at Bristol Crown Court.
Mr Hartley had already admitted a charge of breaching gas safety regulations under the Health and Safety at Work Act 1974 by failing to secure the boiler flue pipe with screws.
The judge described Mr Hartley as “a wholly respectable man” with a good work record.
Judge Neil Ford QC told him: "There is no prospect at all of you committing further offences. This is simply the price that you must pay for an isolated but serious criminal offence."
