## Long description

The Vaillant Flue Air-Exhaust Horizontal Duct 82/125 mm, length 750 mm, model DWZ is a rigid concentric duct designed for balanced-ventilation gas boiler systems. It provides a sealed pathway for combustion air intake and flue gas exhaust in horizontal installations and includes an integrated windshield to limit wind influence at the outdoor termination. The component is intended for use with compatible Vaillant appliances that require a concentric air-flue connection in the 82/125 mm size range.
Advantages
This horizontal air-exhaust duct offers a concentric design that combines air intake and flue exhaust in a single unit, reducing the number of penetrations through exterior walls. The 82/125 mm diameter pairing supports efficient flow for many domestic and light-commercial gas appliances. The included windshield reduces wind-induced draft fluctuations and helps maintain stable combustion and safe discharge of flue gases. Constructed for horizontal routing, the duct is suitable for installations that demand sealed connections and outdoor termination protection.
Suitable for
 Horizontal balanced-ventilation gas boiler installations
 Sealed-concentric air/flue connections where 82/125 mm is specified
 Outdoor terminations requiring wind protection

How to use
Install the concentric duct in accordance with the appliance manufacturer’s installation manual and local regulations. Ensure correct alignment and secure sealing at both the appliance connection and the external wall termination. The horizontal unit must be supported to prevent stress on the appliance outlet and to maintain the correct fall or level as specified by the appliance guidelines. Verify that the windshield is positioned toward prevailing winds if local conditions require additional protection. After installation, perform a system check including tightness, draft behaviour and combustion parameters per service procedures.
Usage recommendations
Use this Vaillant concentric horizontal duct only with compatible Vaillant gas appliances and approved installation kits. Always follow the appliance manual and national gas and building regulations. Periodic visual inspection and clearance of debris at the outdoor termination will help maintain correct air intake and safe exhaust performance.
