Frequently Asked Questions

For what type of installations is this double-walled elbow recommended?

It is designed primarily for flue installations that require sections exposed to the elements or that pass through areas where it is necessary to prevent heat loss and condensation, making it ideal for both pellet stoves and traditional fireplaces.

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

The double wall incorporates a layer of thermal insulation between the inner and outer flue. This keeps the temperature of the combustion gases high, improving chimney draft, and drastically reduces the external temperature of the pipe, increasing fire safety.

Is it compatible with tubes of any brand with a diameter of 150 mm?

Yes, this elbow is standardized for a 150 mm diameter, allowing it to be integrated with the vast majority of modular piping systems on the market. It is recommended to check the male-female connection system to ensure a perfect seal.

How is this stainless steel elbow maintained?

Thanks to the quality of the stainless steel, its interior surface is smooth, which makes it difficult for soot to accumulate excessively. Regular inspections and mechanical cleaning with appropriate brushes are recommended to keep the duct free of obstructions.
