It is applicable to automatic gas burners fitted with a combustion air fan, equipped as described therein, and intended for use in appliances of different types and operated with fuel gases, total pre‑mixed burners and nozzle mixed burners, single burners with a single combustion chamber, single‑fuel and dual‑fuel burners when operating only on gas, and the gas function of dual-fuel burners designed for simultaneous operation on gaseous and liquid fuels (for the latter operation, see also ISO 22968).
It is not applicable to burners used in direct fired processes either with defined combustion chamber applications or where the combustion chamber wall surface temperature is greater than 750 °C or the heat‑transfer medium temperature is greater than 500 °C.
