No he's not. Removing the air from a kitchen does not mean it is removed from a living room. Common sense or not.
The replacement air has to come from somewhere. Where do you suggest it comes from if all external doors and windows are closed. ?Removing the air from a kitchen does not mean it is removed from a living room
The requirement is for a vent for any SF appliance with a NOMINAL output of 5Kw.
If it's a non new build and fundamentally not an air tight property then SF stoves under 5 KW don't need an air vent.

(The installation manual for the 5KW stove I had installed at my previous house)
the manufactures instructions will tell all regarding ventilation. have a look to check if you're unsure.
Will do. I mentioned the vent because I did ask the HETAS chap direct, but I'll check out the instruction manual too.
also in your first post you mentioned that you're in a modernish house, do you have a pre cast chimney? they can be bad for blocking easily, especially when fitted by a builder on a price

I am not sure the salesman is correct. They are designed and rated at maximum output for the recommended fuel. In actual fact, the useful heat is lower than the nominal, as, unless it is hopper fed, it cannot run at max all the time.
the fire is lit because it is a cold day, all windows and external doors are shut, only the flue is still open to the outside, so where does the equal amount [of air] enter the house, down the flue maybe ?
After a while the pressure difference between inside and outside would be greater than that which the fan could over come and thus there would be no more air moved out by the fan.what if you leave the extractor fan on for a while in a house with no chimney and have the doors and windows closed

Not physically possible unless the whole house was hermetically sealed.
On the first service of our inherited gas fire we were told that we needed to open the existing vent (which was already there, but which had been blocked off with a piece of hardboard by the previous owner). However, we used a different RGI for our second service and he told us that there was no such requirement because the output of the gas fire was less than 5kw. The reason why I asked was because this question of how much greater than 5kw the output might be did arise, but no, there was no discussion with the salesman of just how we might be able to achieve additional output for any length of time.
I don't suppose there would be any harm in having a closeable air vent, even if there's no legal requirement to have any vent at all?
