Installing a stainless steel chimney: The complete guide in 5 steps
Are you planning to install your own stainless steel chimney and wondering exactly what the process involves? This guide shows you step by step how to install your OSKAR stainless steel chimney safely, quickly and easily – even with no previous experience.
Why a stainless steel chimney is the right choice
A twin-wall stainless steel chimney offers excellent insulation, high weather resistance and a modern design. Unlike a masonry chimney, it can be configured to suit your individual needs – and its clever connection system also allows installation without a specialist company.
Before starting the installation itself, it is worth taking a quick look at what you will need.
What you need for installation
- Your individually configured stainless steel chimney kit
- Locking bands (included in the kit)
- Wall brackets or rafter supports (depending on the installation type)
- Optional: ladder or scaffolding for roof installation
- Gloves for handling the stainless steel components safely
Step 1: Fit the components together
Assembling an OSKAR chimney is very easy. First, simply fit the components together – with no tools or previous experience required. Make sure that each pipe section fits precisely into the previous one before moving on to the next step.
Step 2: Secure with an anticlockwise turn (SAS-TEC principle)
A gentle anticlockwise turn joins the components firmly and securely – using the tried-and-tested jam-jar principle. No tools, no force, no effort – simply turn and you are done. It is as simple as it is effective!
This connection technology is called SAS-TEC (Secure Adjust System) and is at the heart of every OSKAR chimney: a thread guides the pipe sections securely together, creating a firm and stable connection.
Step 3: Secure the connection with a locking band
To ensure the connection remains completely firm and sealed, it is finally secured with a locking band – for maximum safety that lasts. The locking band is placed around the joint and fastened tightly so that the pipe sections can no longer come loose or twist.
Step 4: Fit the wall or roof support
Depending on the installation type – standard installation, offset installation or roof penetration – the chimney is now secured with wall brackets or rafter supports. Make sure the clearance from the wall or roof meets the manufacturer's specifications so that the thermal insulation works optimally.
Step 5: Final checks and visual inspection
Finally, check all connections again to ensure they are secure. Is every locking-band connection fitted correctly? Is the chimney vertical? Are all supports firmly screwed in place? Installation is complete only once you have checked off every point.
The result: Maximum leak-tightness and durability
The result: maximum leak-tightness and durability you can rely on year after year. And because we believe in our quality, it comes with a warranty of up to 30 years.
All OSKAR stainless steel chimneys are also tested and certified by TÜV SÜD for constancy of performance (DIN EN 1856-1) – for safety you can rely on.
Avoid common installation mistakes
- Incorrect wall clearance: Insufficient clearance can impair the insulation.
- Locking bands not fastened tightly enough: This results in leaking joints.
- Chimney not aligned vertically: This impairs the draught and appearance.
- No visual inspection after installation: Minor faults remain undetected.
Conclusion
Thanks to the Secure Adjust System, even beginners can install a stainless steel chimney with ease. With the right steps – fitting the sections together, turning anticlockwise, securing them with locking bands and fitting the correct supports – nothing stands in the way of your new chimney.
