Frequently Asked Questions

What type of installations is this 80mm elbow recommended for?

This elbow is especially suitable for flue gas evacuation systems in pellet stoves, fireplaces and chimneys that require an 80 mm diameter duct and need to overcome a 45 degree detour in their layout.

Why choose a double-wall system over a single-wall system?

The double wall provides excellent thermal insulation that keeps hot gases inside, improving chimney draft, drastically reducing condensation, and allowing for a shorter safety distance from flammable materials.

Is it compatible with tubes from any manufacturer?

It is designed to market standards for 80mm diameter double-walled pipes, although it is always recommended to check the dimensions and specific joining system of your previous installation to ensure a complete seal.

How is this stainless steel elbow maintained?

Thanks to its smooth stainless steel interior surface, this elbow prevents excessive soot buildup. Annual inspection and cleaning are recommended, coinciding with the regular maintenance of your pellet stove or fireplace.
