depends on many factors, air brick size notwithstanding.

Q for the gas fitters - can BG *condemn* an installation that was
installed per the regs at the time (and is not actually that old), or
should they simply be saying its an "advisory" ?

Is it a ploy to "sell" another system ?

I would have thought an advisory. I was recently servicing a gas fire
which wasn't spilling but stank the room out, ventilation was ok and
as the fire was designed thus all we could do was issue an advisory
on the lack of adequate cross bonding, put a sticker on it and leave.

Is it a ploy to "sell" another system ?

probably. definately worth getting another opinion. I haven't got my regs
book with me at the moment and family gas engineer 1 is drunk and family
gas engineer 2 is incommunicado.

sure someone will be along to answer fully, soon.

BG insisted a neighbour install a vent at the top of the cupboard, above the
door, that her floor mounted boiler is in - despite the fact there is no top
to the cupboard and it's 12" clear of the ceiling. They also made her
change the plug and socket to a double pole switch because that gives 3mm
isolation - a plug easily gives 3 feet!!

There must be something going about.

A gas fitter called to change my sister's gas meter (we do it every 7 to
10 years you know!)

Whilst there he took the opportunity to threaten powers of isolation
because her gas flame effect fire had not been inspected since
installation. Surprisingly he is a contractor and available for
inspection of such units. No comments about the Rayburn gas cooker/room
heater as he is not qualified to inspect those.

Now I know that gas appliances need annual inspections where property is
rented but am unaware of any mandatory inspection requirement for owner
occupier premises.

What say you?

Having seen the replies in this thread I urge people to read the Gas
Fitting FAQ.

As for the OP's friend...

The situation depends on the actual requirements of the appliance and th
amount of ventilation available.

There are two levels of 'condemning' one is absolute it and ID
(Immediately Dangerous) notice and the other is the advisory AR (At Risk).

If the appliance is labelled as ID then the fitting must have had some
reason to believe that the installation was of immediate danger to life or
property.

It does not matter how much ventilation there is: if the flue gases are
not cleared for whatever reason then the installation is ID. Although
(non-BG) independent fitters would probably set about finding and
correcting the fault rather than labelling it.


By and large the standards have not risen (although there are exceptions
e.g. open flued appliances used to be allowed in bathrooms 20+ years ago).
What has happened is the advance of the CCC and more serious inspection
and monitoring of installers, leading to a lot more armour plating on the
hind quarters.

By law the fitter has no right to disconnect the appliance if it's only
"At Risk". There is a recommendation that AR installations are 'made
safe'. However it would a very exceptionally well informed customer who
insisted on the appliance remaining connected in the face of a fitter who
wants to cut it off.

The fitter is saying that due to less ventilation than it should have,
there is a risk of the appliance becoming 'dangerous'.

The correct amount of ventilation is as specified in BS 5440-2 see links
below.

what was the printed sheet, what did it contain as i have never used a
printer/device to measure and calculate ventilation requirements(other
than a tape and calculator). your ventilation requirements are
calculated by room size, appliance type and size amongst other factors,
none of which are contained on a flue gas anyliser that i am aware of if
that is what BG used for this purpose!

i am fairly new to the industry so experience is not my forte but the
current regs and methods are fresh in my head, BG tend to rely on
peoples ignorance too much.

as i say, it's hard to give a 'verdict' over a news group but, if he
says the air vent is too small then it could well be that the appliance
is not getting the air it requires to burn safely and/or efficiently.
his actions depend on the circumstances. he should at least advise you
that the vent is sub standard and requires upgrading although it may me
'legally' acceptable at present.

we always try to inform customers in plain english, after all most
customers like yourself, don't know the 'ins and outs' of gas
safety/requirements. (which is what keeps us in jobs)you would need to
supply the room volume, is there an openable window, is there an

(same place as type, that plate incidently is called a data badge)does
the room connect with any other rooms with fires/open flue boilers that
could effect the appliance. it is a mine field but if ya wanna know the

i have spent loads on training just to get to a stage where i can obtain

It caused me to make BS 5440 available online so we can all be better

This is my take:
If you were to apply all the rules as laid down in the standards to the
letter then _most_ homes would fail in some way.

By far and away gas pipes would be under sized to achieved the required
1mb max pressure drop.
Clearances to combustible surfaces would fail many a cooker (28mm side
clearance required -on each side!), unless otherwise stated.

Ventilation not just for combustion put also for cooling room sealed
appliances.

In practice small infringements are overlooked if all is working well.

With the advent of the CCC etc. Big organisations are going to have to
make sure they comply with the letter of the law.

The brief answer is yes. The following is the text of a reply that I
received from CORGI in May this year.

Ventilation - Setting the record straight

Following two articles in a national newspaper the industry and in
particular
the HSE are concerned that users of gas appliances may now be confused
about the latest ventilation requirements outlined in the fourth edition of
the
industry Unsafe Situations Procedure, and that installers would perhaps feel
reluctant to mention the changes to those customers who would not be
affected until 2008. To help explain the situation the we have published
the
article below and to reinforce the importance of correct ventilation the HSE
have a placed a similar article on their website which you as an Installer
can
refer customers to. http://www.hse.gov.uk/press/record/times170306.htm.

In August 2005 the fourth edition of the Gas Industry Unsafe Situations
Procedure came into being. This superseded the third edition released in
September 2001. As you will know, this procedure is referred to within the
HSC Approved Core of Practice and Guidance on the Gas Safety (Installation
and Use) Regulations 1998.

One of the major changes brought about by the Fourth edition is in the
classification of undersized ventilation for open-flued appliances and
therefore
how any resulting sub-standard ventilation should be dealt with by the CORGI
Registered Installer. The ventilation requirement itself has not changed.

It must be recognised that inadequate ventilation can be a contributory
factor
in unburned gas incidents and of the deaths caused from carbon monoxide
poisoning each year (around 30), 80% of these involve open-flue appliances.
It must also be accepted that gas users will generally treat advice that
their
ventilation provision is 'Not to Current Standards' as a low risk, with the
majority doing very little to improve the ventilation provision in their
homes.

An industry panel including CORGI and the HSE together with a number of
CORGI Registered Installers were involved in risk assessing installations
with
undersized air vents to determine how the air vents should be brought up to
the required level without creating unnecessary inconvenience or risk to gas
users. It was acknowledged that hundreds of thousands of installations could
be affected and whilst this was a small proportion of the total gas
installations
(some 24 million) the potential risks in relation to under-sized ventilation
are
such that this required proper action.

In recognition of the difficulties of immediately moving to full compliance
on
existing installations, a step change was introduced to manage the situation
over a period of time ensuring that after June 2008, all ventilation
provision
will comply with the required standard, tackling those with the greatest
deviance from the standard first. This change was published in the fourth
edition of the Gas Industry Unsafe Situations Procedure.

To achieve this step change, existing open-flued appliances installed in
rooms
where the ventilation is 39% or less, or in compartments where the
ventilation
is 90% or less of that recommended by the appliance manufacturer's
installation instructions or appropriate industry standard would be
classified as
'At Risk' (AR) and with the customers permission should be turned off .with
immediate effect (i.e.. from the fourth edition coming into effect in August
2005). Where the ventilation requirement is between 40% to 89% of the
requirement recommended by the appliance manufacturer's installation
instructions or the appropriate industry standard and the appliance is
operating safely, it can be classified as NCS and left operating. The gas
user
should be advised in writing that this is a temporary situation that must be
brought up to current industry standards before 1st June 2008.

Installations providing between 90 and 100% of the ventilation requirement
should be classified as satisfactory due to the difficulties in measuring
the
small apertures normally found on a ventilator grille.

Therefore, CORGI registered Installers who encounter undersized ventilation
should treat the installations in the following manner:

* Open-flued appliance with 39% or less of the ventilation requirement -
At Risk with immediate effect and the appliance should be turned off..

* Open-flued appliance installed in a compartment with less than 90% of
the ventilation requirement - At Risk with immediate effect and the
appliance should be turned off.

* Open-flued appliance with ventilation between 40% and 89 % of the
requirement - NCS until 1st June 2008. The gas user must be informed
that this situation will become At Risk on 1st June 2008. This affords
the gas user the maximum possible opportunity to improve the
ventilation before having the inconvenience of the appliance being
turned off.

Following 1st June 2008, all installations must comply with the current
standards for ventilation provision and if they do not then the CORGI
registered Installers MUST inform the gas user that the appliance should be
turned off until the ventilation provision can be upgraded.

Whilst there is a two-year timeframe, gas appliances do need air for good
combustion and gas users should be advised that any ventilation upgrades
that are suggested by their gas Installer should be completed sooner rather
than later.

As previously mentioned the fourth edition of the Gas Industry Unsafe
Situations Procedure was published following a thorough revision by an
industry group that included HSE and CORGI and included consultation with
the major stakeholders within the industry. It was particularly important
that
the group included the HSE and they together with the other members of the
group approved the procedure prior to publication and continue to support
the
procedure including the recommendations on improving undersized ventilation
provision. Any non-compliance with the provisions of the Gas Industry
Unsafe
Situations Procedure by any CORGI Registered Installer will be taken very
seriously by the HSE.

I can understand them hiding this away, in the hope that nobody will
find out about their retrospective changes until later.
