EN 13611:2019, Clause 1 is replaced by the following: This document specifies the safety, design, construction and performance requirements, and testing for automatic burner control systems, programming units, flame detector devices and High Temperature Operation (HTO) detectors, intended for use with gas and oil burners and gas and oil burning appliances, with or without fans and similar use. This document is applicable to automatic burner control systems that include additional functions. This document is not applicable to automatic burner control systems utilizing thermo-electric flame supervision devices. NOTE Standards for burners, appliances or processes which use automatic burner control systems, programming units, flame detectors or HTO detectors can override the requirements of this document.
