Gas Work Question

What is the difference between flue and flueless gas fires?

I have just removed a really old stone fireplace from my living room, and now there is a big gap between my old gas fire and the wall. I want to get a new more modern gas fire to put against the wall but I dont know what to get, what is the difference between flue and flueless fires??

The fire i have at the moment is free-standing, but there was a hole in the fireplace backing onto the fire leading up to the chimney pipe, is this anything to do with it?

Hope someone can help shed some light on this for me!!!

Need a Gas Engineer?

Hi there,the chimney is your flue.
It will need to be tested to make sure it is sound before fitting a replacement.
So you should not need a flueless fire.

A flued gas Fire needs a Chimney which has been inspected and tested by a registered gassafe gas fire engineer.

A flueless gas fire does not need a chimney but still has to be installed by a gassafe gas fire enginner to ensure adequacy of ventilation according to room size and test the combustion once installed.

Only A gassafe engineer can warranty the safety of such items and not the manufacturer.

You should go on the gassafe register website and choose an engineer that has gasfire on their list of qualifications.

A flueless gas fire does not need to have a flue directly to outside.It may however need some other source of ventilation this is dependant on the room and the size.In your case the chimney is the flue.
