BS EN 14989-2 is the second part of the multiple series that specifies requirements and test methods for metal flue ducts material independent air supply ducts for room sealed appliances.
BS EN 14989-2 also specifies the requirements for marking, manufacturer's instruction, product information, and evaluation of conformity.
Note: In BS EN 14989-2, only general requirements are specified for elastomeric and plastic components. Elastomeric and plastic products used in flue systems are covered by separate standards, i.e., EN 14241-1 and EN 14471.
BS EN 14989-2 on flue and air supply ducts for room sealed appliances is useful for:
The air supply duct is the independent duct in a building or an integral part of an air/flue configuration conveying combustion air to a room sealed appliance and a flue duct is used for conveying the products of combustion.
BS EN 14989-2 specifies flue and air supply ducts for room sealed appliances in which the combustion air supply duct and flue duct are separate or as a concentric configuration. BS EN 14989-2 specifies push-in spigots of the flue/air supply duct that is capable of being pushed into the socket of the gas appliance. BS EN 14989-2 also specifies thermal testing s on the largest diameter up to and including 200 mm. All diameters within a range of products of the same design and designation will help you to meet the requirements met by the tested samples.
Overall, BS EN 14989-2 assists you with the combination of the chimney and air supply duct needed for the correct functioning of a room sealed appliance.
