From 1st of January 2013 all flues in voids will require inspection hatches to inspect all joins in the flue. There will be an automatic “At Risk” added to the report even if the appliance and flue pass all checks.
An “AT RISK” added to a gas safety report means we would ask your permission to turn the appliance off.
A flue in a void is where the flue (basically an exhaust pipe), instead of running straight out of the back of the boiler, through a wall and outside, it has to travel through other rooms first within a void (so via a wall, ceiling or floor).
This only applies to flues that have fans in them to push the exhaust fumes out, some do not have this and rely on natural ventilation and draughts.
Along the length of the flue there now needs to be a way of checking the inside to make sure all is well, 30cm square (12″) inspection hatches need to be fitted close to every join, not more than 1.5 m (60″)
That way subsequent Gas Safety engineer can make sure there are no Carbon Monoxide and other poisonous gases leaking around the joins.
There is some important advice for consumers who have flues which run in ceiling spaces:
Some properties, mainly flats and apartments, have been built with boiler flues which cannot be inspected because they are hidden behind walls or ceilings. The boiler flues that this information relates to are connected to room sealed fan assisted boilers. If you live in one of these homes then please read on for more information so you know what to do.
Gas Safe registered engineers need to be able to see the flue – which take fumes away from the boiler – as part of essential safety checks whenever the boiler is worked on. A flue in poor condition, combined with a boiler that is not working properly, could put you and your family in danger from carbon monoxide poisoning, which can cause death or serious injury.
If your boiler is situated on an outside wall, it is unlikely you have this type of flue. Alternatively, if your engineer can see all of the flue, you will not need to take any further action in relation to this matter.
If you do have a boiler where all, or part of, the flue cannot be seen, you, or your landlord, will need to arrange for inspection hatches to be fitted. This does not mean that your flue system is suddenly unsafe.
Carbon monoxide alarms are not an alternative to being able to see the flue and you will still need to have inspection hatches fitted. It is recommended that inspection hatches are fitted as soon as you are able to do so. From 1 January 2013, any Gas Safe registered engineer will turn the boiler off, with your permission and formally advise you not to use it until inspection hatches have been fitted in appropriate places.
Although most of the affected boiler and flue systems are relatively new (installed since 2000), the risk of faults leading to the release of carbon monoxide increases as the system gets older, especially if it is not serviced regularly. It is important that you have your gas appliances serviced annually.
If you are a tenant, it is the responsibility of your landlord to ensure that inspection hatches are installed and that the boiler and flue are checked every year.
IF IN DOUBT THE METAL FIRE RATED TYPE IS THE SAFEST OPTION
Unfortunately it will not be until we cut out the opening that we can truly identify whether the boxing/ceiling is either cosmetic or fire rated.
However from my experience of flat/ house conversions, new build houses and flats the boiler would be part of the second fix and the ceilings and walls would already be installed and therefore if the boiler flue doesn’t go straight out an external wall directly behind or above but goes out at another position then the boxing in of the flue would be done more for cosmetic reasons.
Legal Requirements: Initial installation and inspection annually for landlords.
Recommended: Initial installation and inspection annually for home-owners.
