As of April 2014, installers will be legally required to record levels of flue has carbon monoxide (CO) and the combustion ratio when commissioning condensing boilers.
Part of new Benchmark Commissioning Checklists, this new requirement is designed to protect installers by proving that they have left an appliance running safely and efficiently. There are fears, however, that many operatives are unaware of the new rules and that this now a legal obligation.
The legislation follows concerns arising from a very small number of CO incidents involving newly-commissioning condensing boilers. The concerns have led the Heating and Hot water Industry Council (HHIC) to work alongside manufacturers, and other industry organisations, to develop a means of checking and recording CO levels and combustion ratio (CO/CO2) in the boiler flue gases, as part of the commissioning process.
To complete the flue gas test to the new required standard, installers will need a BS 7967 specified electronic combustion gas analyser with a valid calibration certificate. As part of the new Benchmark Commissioning Checklists, the legislation requires the installer to leave the completed checklist with the boiler.
It has also been recommended that installers advise customers to fit a CO detector with an audible alarm in their homes, in addition to an annual service; something that is already mandatory in Northern Ireland and Scotland.
Full background details of the legislation can be found here.
For installers needing to refresh or familiarise themselves on CO and CO2 safety, we offer:
- Core Domestic Natural Gas safety training and assessment course (CCN1)
- Carbon Monoxide/Dioxide Atmosphere and Appliance Testing training and assessment course (CMDDA1).
