Brand: Baxi
Model Number: 7225716
Product Description:

Under the Multifit brand, the telescopic flue kit for Baxi boilers provides
a length of 350 – 500 mm, and flue lengths are available in 0.25 meter, 0.5 meter, and 1 meter.
This means that there is hardly ever a need to cut a length of flue,
reducing installation time and wastage, which is a particular consideration for new builds.
The flue sections are joined using a simple push seal mechanism with two positive screw connections giving reassurance that the joint will not come apart.
