Single-wall Flue Pipe VIESSMANN 150 mm, Length 1000 mm, Model 7739475

Single-wall flue pipe VIESSMANN 150 mm, length 1000 mm, model 7739475 is a straight stainless steel duct intended for connecting heating appliances to flue systems. The pipe has a nominal diameter of 150 mm and a one-metre length, providing a rigid, single-wall passage for exhaust gases. It is designed for use with conventional boilers and furnaces where a single-wall flue is appropriate and can be installed in horizontal or vertical runs when combined with the correct clearances and compatible fittings.

Advantages

The stainless steel construction offers corrosion resistance and dimensional stability at typical flue gas temperatures. The straight 1000 mm length reduces the number of joints required in a run, simplifying installation and improving flow characteristics. The 150 mm nominal diameter matches common heating appliance outlets, enabling a secure mechanical connection with standard single-wall components.

Suitable for

• Connecting conventional gas, oil or solid-fuel boilers to a single-wall flue system
• Horizontal or vertical flue sections where single-wall tubing is permitted
• Replacement or extension of existing single-wall stainless flue runs

Key specifications

• Material: stainless steel
• Nominal diameter: 150 mm
• Length: 1000 mm
• Construction: single-wall, straight
• Application: exhaust flue duct for heating appliances

How to use

Select the pipe to match the appliance outlet diameter and ensure that all fittings, supports and clearances comply with the appliance manufacturer’s installation instructions and local building codes. Cut or join sections as required using compatible connectors and secure mechanical joints. Maintain required clearances to combustible materials and provide appropriate support at recommended intervals to prevent sagging. Ensure the flue path provides proper draft and that condensate and soot access points are considered for maintenance.

Usage recommendations

Inspect mating components and gaskets before installation, follow the boiler or furnace manufacturer’s guidelines for single-wall venting, and schedule periodic inspections to check for corrosion, leaks or obstructions in the flue run.
