Air‑flue Duct DN60, Clarks, length 2000 mm

Clarks air-flue duct DN60, length 2000 mm, is a straight circular conduit designed for conveying combustion gases and air in heating and ventilation installations. The 60 mm nominal diameter (DN60) suits small boilers, heaters and exhaust connections where a compact flue or air intake pipe is required. Constructed for inline installation, this duct provides a continuous passage for flue gases and intake air in residential and light commercial systems.

Advantages

The fixed 2000 mm length reduces the number of joints needed for runs of moderate length, improving installation speed and reducing potential leak points. The DN60 profile is compact and compatible with small combustion appliances, offering a standardized diameter for straightforward mating with collars, couplings or appliance outlets. The smooth circular geometry helps maintain efficient gas flow and simplifies cleaning and inspection compared with irregular shapes.

Suitable for

• Connection to small residential boilers and water heaters requiring a 60 mm nominal flue.
• Exhaust lines for compact heating units and room heaters.
• Air intake or combustion air ducts where DN60 is specified.
• Light commercial ventilation runs with short to medium-length straight sections.

Key specifications

• Nominal diameter: 60 mm (DN60)
• Length: 2000 mm
• Shape: circular tube
• Application: air and flue gas conveyance in heating and ventilation systems
• Compatibility: designed to mate with standard 60 mm flue collars and couplings

How to use

Select the air-flue duct as part of a complete flue or intake system sized for the appliance and installation. Cut or position the duct so its ends align with adjacent flue components, appliance outlets or couplings. Ensure seals, gaskets or approved jointing methods are used where required by local codes and manufacturer instructions to maintain a gas-tight connection. Support the duct at regular intervals to prevent sagging and to comply with mounting recommendations for the overall system. Verify the assembled system for correct draft and absence of leaks before placing the appliance into regular service.

Usage recommendations

Use this DN60 duct only with appliances and installations rated for a 60 mm nominal flue. Follow local building and gas safety regulations for flue routing, clearances and sealing. Periodically inspect the duct for corrosion, blockages or joint deterioration and clean or replace components as needed to maintain safe operation.
