ESV has received numerous reports of CO detectors giving false or misleading readings when used to measure spillage from either a space heating appliance or central heating duct air supply register. These readings are a result of the way in which CO detection equipment has been used, with instruments being exposed to temperatures greater than their maximum rated temperature. Gasfitters need to be aware of, and take into consideration, the limitation of their equipment. Each type of CO detector available will have a maximum temperature limit provided by the manufacturer, and when the detector experiences temperatures in excess of this limit it will no longer provide an accurate reading. Many CO detectors have a maximum operating temperature of between 40°C and 50°C. These CO detectors are designed for the measurement of ambient CO levels within a room, and are not designed to measure CO in a heater’s discharge air stream.
