16 Gas conversion adjustments

In order to operate with a gas other than that provided from the
factory, it is necessary to some adjustments to the gas valve.
This conversion should only be carried out by a competent
person approved at the time by the Health and Safety
Executive.
• During the conversion to Propane, use of a suitable flue gas
analyser is necessary.
The person carrying out a combustion measurement should
have been assessed as competent in the use of a flue gas
analyser and the interpretation of the results.
The flue gas analyser used should be one meeting the
requirements of BS7927 or BS-EN50379-3 and be calibrated in
accordance with the analyser manufacturers' requirements.
Competence can be demonstrated by satisfactory completion of
the CPA1 ACS assessment, which covers the use of electronic
portable combustion gas analysers in accordance with BS
7967, parts 1 to 4.
