I have recently bought a flueless gas fire for my house that was a bit of an impulse purchase as it was in the sale. It is a new property and has no fireplace at all. It is a modern looking wall mounted fire. We have a gas pipe and a socket in place ready but I have since noticed we might require extra ventilation?! Could this go behind a radiator so help hide it?

No, it has to be unresticted & your room will freeze once this silly vent is fitted.

You'll need a 5" dia wall vent to give the correct surface area for ventalation with out it a gas fitter wont install the fire - I put one in my last house and cost about 25 quid from the local builders merchants. Took a while to drill the hole for it though. Hid it behind some curtains for the patio door

yes

We opted for this as an extra on our new build home, really wish we hadn't.

It'll depend on how sheltered the side of the house is that the vent is to exit on, but if like mine it's exposed, the draught in the lounge is really noticeable and the fire only ever gets turned on to combat the draught, rather than becuase we want it on.

Instead of the vent can you just get a decent Carbon Dioxide detector.
My understanding (although extremely limited smile ) was that the vent is only needed in case of a failure of the cat.

Make a cardboard cover that seals it off wink We never use the fire(no need)it was 100% decorative. We had a much nicer fire before this one that had a fan flue, trouble was the draught from that one was even worse!! Someone should invent a fan flue that closes off when not in use, can't be that hard, & with a carbon monoxide detector that switches the gas off if the flap failed would be safe as anything....

Im assuming then, that the vents accross the tops of my windows/french doors will not suffice.......

Afraid not as they can be closed.

It must have ventilation, cat or no cat, you are burning oxygen and this needs to be replaced. If not you get incomplete combustion which in turn leads to carbon monoxide being produced.

A carbon monoxide detector is not a substitute for ventilation, I've met too many people who have experienced the first symptoms of CO poisoning, its quite sobering.

Personally I'd sell the fire, I dislike flue-less appliances, except cookers.

Last I heard the register of gas installers were advising their members not to fit, service or repair flueless fires. They're also banned in America afaik. I chatted to a plumber a couple of weeks ago who'd been to one with a failed cat - without a carbon monoxide detector he carried noone would have been any the wiser.
Take that whichever way you want.

If on an outside wall you could sell it and get a balanced flue fire ( just vents straight out the back)??

Im starting tot hink maybe I should just return it and look for something else. On paper it sounds like a great idea but the more I read about it them more I am less convinced. It is on an outside wall so I guess a balanced flue fire could be an option. Would this do away with the 100cm air brick requirement?

Gas fires rated at under 7kW don't require a vent. Flueless fires similarly WOULDN'T, but they require a vent to dilute the products of combustion which is different to the combustion air requirement hence the big vent specified.

Like many gas engineers I don't like them and would always try to steer people away. Yes, they are safe, but when people's wellbeing relies on your decisions, I find I'm happier saying no.

Reminded me of this case................

This was a brand new fire sent out faulty by the manufacturer.

That's very interesting. These fora have long been populated by people decrying the need for Gas fitters 'Gas Safe' status. How many 'have-a-go' gas men would have checked that pressure, I wonder? Best get someone qualified in...

Flueless fires are not banned in America, the catalytic techology used in the Focal Point UK units is used under licence from Lennox Insustries in the States.

Faulty or not, it should have been checked. I was told this story when doing my gas training, I'm pretty sure the vent was in the wrong place aswell.

People who don't know about gas would be scared stless if they had to do the training, I was a nervous wreck for the first few weeks after passing. I was known as "The condemner" by my workmates because I shut down so many boilers in my paranoid state!

I've had a google, and I stand corrected - they aren't banned in the US.
But on the other hand...
And that googling also found this. How relevant and/or accurate it is, I don't know. But I'll be sticking with a woodstove and dirty great 6" flue.

Yup, I have a balanced flue fire, matchless HErs I think? Very good, vents straight out the back so no air brick and 80% efficiency iirc.
