Frequently Asked Questions

How do you install the anti-backdraft cap on the chimney pipe?

This chimney cap fits directly onto the top nozzle of a 150 mm flue. Its design ensures a firm and secure fit. It is recommended to secure it with specific metal clamps or self-tapping screws to guarantee it remains firmly in place even in strong gusts of wind.

Why is smoke coming into my house and how does this chimney cap help solve it?

Backdraft often occurs when the wind hits the chimney outlet at an unnatural angle, creating a downward draft that pushes smoke inwards. The backdraft cap breaks these drafts thanks to its deflector design, channeling the gases outwards and harnessing wind speed to improve chimney suction and draft.

Is this model compatible with any type of stove or fuel?

Yes, this 150 mm chimney cap is suitable for flue systems of wood stoves, pellet stoves, traditional wood-burning fireplaces, and gas or oil boilers. Its vitreous enamel finish perfectly withstands combustion residue and soot without suffering structural damage.

Does it require any special maintenance?

The vitreous enamel coating provides a smooth, non-porous surface that makes it difficult for soot and dirt to adhere. However, it is advisable to perform a visual inspection and annual cleaning of the flue and chimney cap at the start of the heating season to ensure optimal and safe draft.
