Below are some common concerns that people often have with regard to the fan flue being too close to an open-able window:
- Distance of fanned flue from openable window
How do you measure this distance in the first place? The outside of the fanned flue should be measured up to the open side of the window. Don’t get confused and mistakenly measure the centre of the flue to the window or the window itself when it is closed. Another important point to keep in mind is the direction of the flue. The flue should be pointing away from the window, not towards it.
- Why is the flue on the boiler recently tagged as “At Risk” for being too close to the window when there was no such problem for the last 10 years?
Regardless of when the flue was fitted, if done incorrectly, it will be tagged as “At Risk”, unless stated otherwise by the gas safe registered engineer. If the flue is simply not up to current standards, the gas engineer may still classify it as being “At Risk”. This is because if anyone is injured from this, then no one will have the rights to point hands at him since he has already classified the flue as “At Risk”.
- Why has my boiler flue been fitted so close to the window? Is this safe?
If the flue is too close to the window, this will be categorized as negligence to life safety. This often occurs when the engineer has taken an incorrect measurement of the flue to window distance or has not taken the window into consideration at all.
- When a flue is too close to an open-able window, what is the technical reference for this error?
If by default, the boiler flue is located too close to an open-able window, this is known as an AR situation. If the gas safety engineer agrees to undertake full responsibility for injury to occupants, the classification is NCS.
- Why is it dangerous if a boiler flue is placed too close to a window?
This is dangerous because if the fumes from the boiler come into the house, the life of the residents will be at high risk. The more the fumes that enter the home, the higher the health risk to the residents.
- Is it allowed to locate the boiler flue under my window?
You can have a flue located under your window as long as it is outside the 300mm regulation. One would say that the likelihood of getting fumes into the home is higher from a flue under the window than from above or sideways, but regulations are regulations and as long as the regulations are followed, a gas safe engineer should not worry about any other probabilities.
- Are there any possibilities to get away from the danger of the flue being too close to the window without having to move the flue itself?
You could either purchase an extendable kit for the flume if such parts are available in the market or you could replace the window with one that stays permanently closed.
- From where does the distance measurement begin for the flue in determining that it is too close to an open-able window?
The exterior of the flue, coming from the wall, and the point where the fumes enter the atmosphere is where the measurement begins for the flue.
- What do I do if my neighbour’s boiler flue is too close to my window?
If your neighbour’s flue is within two meters of your property, you should report this to the headquarters and they should stop using the flue as it is tagged as “At Risk”.
- How do I know if the gas engineer is genuinely tagging my flue as “At Risk” or he’s just saving himself in case of injury to any residents?
If your gas engineer demands you to take off your boiler due to the flue being too close to a window, he is not trying to make money, he is doing so because he knows his responsibilities. In fact when removing the boiler which has a flue too close to a window, the costs involved are more because the work is more.
