BS5871 Part 1

[Alice]

Please can anyone give me some advice on BS5871 Part 1?

I have a 5.5kw gas fire installed approx 18 months ago in a 100 year old, property....do I need to have a vent/air brick to be compliant?

 

[Dotty]

What make and model is the fire Alice?

 

[lame plumber]

your installation manual should give you the answer if the installer left it behind as they should

 

[Dotty]

Which is why I asked....

Let's be a little more helpfull where we can shall we?

Thank you for the quick responses.

It's a Firefox 5. The installer did leave the manual, but in the ventilation section, it just says to refer to BS5871 Part 1

 

[lame plumber]

oi, I was trying to help the lass, normally around page 2 or 3 it tells you no additional ventilation required, blinkin commercial techies

I don't normally deal with domestic fires Alice, as Mr Grumpy just alluded, but there is a threshold at which additional ventilation is required. Your fire is below that threshold.

Don't forget it'll need servicing just like any other heat producing appliance.

Thanks so much for your help

Ventilation.
Normal adventitious ventilation is usually sufficient to satisfy the ventilation
requirements of this appliance. In GB reference should be made to BS5871 Part 1
and in IE reference should be made to the current edition of IS 813 “ Domestic gas
installations” which make clear the conditions that must be met to demonstrate that
sufficient ventilation is available.
An extractor fan may only be used in the same room as this appliance, or in any
area from which ventilation for the appliance is taken, if it does not affect the safe
performance of the appliance. Note the spillage test requirements detailed further on
in this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.


oops page 13, clear as a bell, adventitious ventilation will apply if you have a nice big room, just begs the question, why are you asking at this stage down the line?

From a point of safety a Carbon Monoxide alarm is advised if you do not have one already.

The manual states ''advantageous air'' is all that is needed,so you not need an air brick or vent for this appliance in normal installations,any reference to BS5871 Part 1 would have been taken into account automatically by the installer,as long as the installer was gas safe.if you have any quires about the installation,just contact the installer and am sure they can put your mind at rest
I would add the appliance should be serviced every year an as in has been in now for 18 months,you should get it checked and would also advise that you think of investing the small amount required to purchase a co2 alarm as previously advised

The room is only 11ft square ( approximately), would this still be ok, as quite a small room?

 

[Chalked]

If the flue does not draw very well. It will need one fitted.

why are you asking after 18 months.? Has an engineer advised?

 

[lame plumber]

knew that one was coming, as above, if it fails a smoke test vent the room

 

[Alice]

It's all working fine, but we're moving, and it's come up on a report

Due to the size of the room, it would therefore be best to get someone to check it?

 

[newcastle phill]

And also make sure you have a suitable carbon monoxide alarm fitted appropriately

When the fire was installed your room size and the output only 5.5 kw then no ventilation needed but now it's been in for couple years nearly an engineer may advise additional ventilation to adhere to safety aspects and best to comply.

BS 5871 is a british standard and covers the selection of a suitable appliance, the ventilation and flueing requirements, and other measures necessary to ensure a safe installation.
