Burton Magistrates Court heard Mr Buratti had, following a chimney fire, organised repair work to a solid fuel burning appliance through two painters and decorators known as Select.
After the occupant of the home - in Sutton Coldfield, Birmingham - began suffering symptoms similar to those of carbon monoxide poisoning, it was discovered an incorrect flue liner had been used. The repair work also included a number of other faults.
Mr Buratti pleaded guilty to a breach of the Health and Safety at Work Act. He was ordered to pay £3,750 in costs.
HSE inspector Dr Janice Dale said: "The dangers of incorrectly specified flue liners and incorrect installations are well known in trades associated with building and refurbishment.
"This case should serve as a reminder to the general public that anyone they ask to undertake work on a gas-fired or solid fuel appliance should be a specialist in that particular field. This case should also be a warning to traders that they must only undertake work for which they are qualified and competent."
