Length of exit flue from boiler

[Lenc2014]

I am inthe very early stages of deciding the layout of my new kitchen.
Cansomeone please tell me if (in principle) it is possible to install a combiboiler on a wall where the “chimney” flue needs to exit the top of the boilerand turn at right angles, then travel almost 1.5 metres to the outside of theexterior wall.
Is thisdistance of travel excessive ?
I willemploy a professional to do the installation work when ready but would like toknow (in principal if the above is possible
Manythanks in advance for any advice offered

Most boiler can flue this distance. It can't be boxed in without access to joints. Any local gas safe registered installer would be happy to advise you. But would need to see the job.

It won’t be right angle but it’s possible. Get a Gas Safe engineer in to tell you more.
