Frequently Asked Questions

What type of installations is this plug recommended for?

It is designed primarily for flue gas evacuation systems, chimneys and pellet stoves that require 80mm double-walled ducts to ensure thermal insulation and safety against condensation.

Why is it important that it be double-walled?

The double wall includes an insulation chamber that maintains the temperature of the gases inside the duct, improving draft, preventing sudden cooling and preventing excessive accumulation of condensate and soot.

How is maintenance performed on this type of plug?

Thanks to its accessible design, it allows for quick and easy inspection, purging, and cleaning tasks, helping to maintain the installation in optimal performance and safety conditions.

Is it compatible with any 80mm pellet stove?

Yes, with a standard nominal diameter of 80 mm, it integrates perfectly into most pellet flues and evacuation pipes on the market that use this same technical standard.
