Frequently Asked Questions

What is the purpose of an 87° flue bend?

An 87° flue bend changes the direction of the flue run by close to a right angle. It is commonly used to avoid obstacles, create a vertical rise from the boiler, or form a raised horizontal flue route.

Which flue size does this Vaillant bend suit?

This bend is designed for a 60/100 mm concentric flue system. Always confirm compatibility with the exact boiler model and flue components before ordering.

Can it be used with Vaillant ecoTEC boilers?

Yes, it is intended for compatible Vaillant ecoTEC condensing boilers using the relevant 60/100 mm flue system. The boiler and flue installation instructions should always be followed.

Does using a bend affect the maximum flue length?

Yes. Bends add resistance to the flue run, so the boiler manufacturer’s instructions may require an allowance to be deducted from the maximum permitted flue length. Check the specific installation manual before finalising the route.

Who should install this flue bend?

A competent heating installer should install the flue bend in accordance with Vaillant’s instructions and relevant UK gas safety and building regulations.
