Regarding this, should a boiler flue be level?
Flues facing public spaces Flue regulations are not only in place to keep your home safe but the people passing by your property too. If your boiler flue has to face out onto a public space, the installer will have to ensure that it's fitted at least 2.1 metres above ground level, over head height.

Also to know is, how far can you run a boiler flue?
For example, a 60/100mm concentric flue fitted to a system or combi boiler can be a maximum of 10m long. If the installation needs the flue to run for a distance above this, the installer can increase the flue size to 80/125mm, allowing for a maximum length of 20m.
Is boiler flue gas dangerous?
Boiler flues are a crucial part of your heating system. If your boiler isn't burning the gas correctly, carbon monoxide could be produced too. Boilers are made to be safe, and these gases shouldn't harm you. However, a blocked flue can mean the gases become trapped in your home, causing you to breathe them in.
