Frequently Asked Questions

What type of heating systems is this elbow compatible with?

This elbow is primarily designed for flue gas evacuation systems in pellet stoves, traditional fireplaces and boilers that require a stainless steel duct with a diameter of 200 mm.

Can it be installed on the exterior of the house?

As it is a single-walled duct, it is recommended for use inside buildings or as part of a pre-existing system that has adequate insulation, since single walls do not have a protective thermal layer against the cold outside.

How is this elbow cleaned and maintained?

Thanks to the smooth surface of the stainless steel, soot buildup is significantly reduced. Annual cleaning with compatible 200 mm diameter cleaning brushes is recommended to keep the duct clear and safe.

Is it resistant to condensation corrosion?

Yes, the stainless steel used in its manufacture offers excellent protection against moisture and acids generated during combustion, guaranteeing a long service life without structural deterioration.
