The Vaillant 470mm air flue extension provides a highly practical structural solution designed to safely elongate the exhaust pathway of modern condensing boilers. Manufactured to bridge the gap between existing flue elbows this rigid 100mm diameter duct allows heating engineers to extend the standard horizontal extraction route by up to half a metre. Weighing a mere 0.82kg it drastically enhances installation flexibility in complex domestic environments where standard extraction lengths cannot reach the desired exterior termination point. Its streamlined architectural profile guarantees an uninterrupted flow of both fresh intake air and expelled combustion gases.
Constructed from highly durable materials capable of withstanding acidic condensation this extension piece is fully compatible with the entire range of Vaillant high-efficiency ecoTEC heating appliances. The component integrates seamlessly into existing ductwork utilising precision-engineered push-fit connectors that establish a secure factory-grade seal without the need for specialized crimping tools or external sealants. This ensures a rapid airtight assembly process that strictly maintains the operational safety of the boiler. Designed for ultimate versatility the extension is equally certified for use within both horizontal through-the-wall layouts and complex vertical roof extractions.
Q: What is the primary function of this structural flue extension?
A: It is engineered to seamlessly bridge the gap between flue elbows extending the exhaust pathway by up to 500mm.
Q: Which boiler series is this extraction component compatible with?
A: The duct is specifically manufactured for integration with the complete range of Vaillant high-efficiency ecoTEC condensing boilers.
Q: Can this pipe be utilised in vertical roof extraction systems?
A: It is fully certified and technically designed to operate effectively within both vertical and horizontal exhaust configurations.
Q: How does this extension connect to existing exhaust pipework?
A: The unit features precision push-fit connectors that ensure a rapid airtight seal without requiring additional mechanical fastening.
