Overview

Independent draught regulators are for the purpose of reducing negative pressure that is too large in the chimney, which can result through the use of commercially available cross-section dimensions, despite being designed, for example, according to EN 13384-1:2015 "Chimneys - Thermal and fluid dynamic calculation methods - Part 1: Chimneys serving one combustion appliance". They serve to increase the flue gas speed and the ventilation of the chimney, for the purpose of drying out (see explanations). Standstill opening devices interlocked with the combustion system are exclusively for the purpose of ventilating the chimney during standby. This European Standard specifies the requirements and test methods for draught regulators, standstill opening devices and combined secondary air devices that are used as components, carrying flue gases, in order to limit the draught in chimneys and provide secondary air to the chimney. Draught regulators, standstill opening devices and combined secondary air devices for positive pressure chimneys are not covered by this standard. It also specifies the requirements for marking, manufacturers' instruction, product information and attestation and verification of constancy of performance. The committee responsible for this standard is NA 005-11-39 AA "Abgasanlagen (SpA zu CEN/TC 166, CEN/TC 166/WG 1 und WG 2)" ("Chimneys (national mirror committee for CEN/TC 166 and CEN/TC 166/WG 1 and WG 2)") at DIN.
