Gas Work

Wall ventilation.

I have read the question and answer relating to the gas fire and venting in a flat. My question is this:
We have a coal effect gas fire which is just under 7kw. When an engineer came round to assess for cavity wall insulation, he insisted that we need a wall vent. (We have carbon monoxide alertors installed). The insulation was due to be fitted yesterday - 19th - but delays in the arrival of the installers has meant we are now having this work done next week.However, one of the installers insists that a wall vent is NOT needed and although he showed me the British Gas "bible" which states, if I remember correctly, anything up to 7kw does not need a vent installed in the wall (as previously mentioned in the reply to the letter I read), I am very confused. So.... do we need a wall air vent or not??? (I am not sure what a basket effect fire is. Would this be the same as a coal effect one?)
Advice would be appreciated. Thank you.

All D.F.E (basket fires) require at least 100cm2 of permanant ventilation UNLESS manufacturers state otherwise.
