I Want A Flueless Gas Fire, What Do I Need?

Regardless of who the manufacturer is Flueless Gas Fires require the following

AIR VENT:
Flueless gas fires require an air vent in the wall to provide a natural source of fresh air. The myth is that this will cause drafts. Modern air vents are designed not to cause drafts and have a shield on the outside. When choosing a vent for your home to go with your flueless gas fire always select a high quality vent. Vents such as the 'Black Hole' Vent consist of a series of baffles that reduces direct drafts and also reduces any noise that could travel through the vent.

The size of the vent depends on the kW rating of the fire. The minimum is 100cm2 of "free air". The larger the kW rating of the flue-less gas fire the larger the vent.  

WINDOW:

The room in which the Flueless gas fire is to be installed must also contain a window which can be opened if required (The window does not need to be open when the flue-less fire is on)

ROOM VOLUME: 
Every flueless gas fire has a "minimum" room space that it can be allowed to be installed in, e.g. 30m3 in the case of the Acquisitions X-Fire 1000 Flueless Gas Fire. This is quoted by the manufacturer as the minimum volume based on width x height x depth in cubic metres.

As long as the room is the same or larger than the minimum, the fire can be installed. This is based on the heat output of the fire, the larger the Kilowatt rating of the appliance the larger the room needs to be.

OTHER REQUIREMENTS:

Flueless gas fires cannot be installed in bedrooms, bathrooms or basements (unless the basement is open on one side)

While a flue-less gas fire could look stunning in the kitchen, it is not normally recommended by manufacturers. This is due to the high content of moist air in this type of room that will be drawn into the appliance.
Flueless Gas Fires are designed to provide a secondary heat source only and cannot be used as the only form of heating in the room.

There are strict rules regarding recessing of a flueless gas fire into the wall and placing objects above them. Check the technical specification or discuss with your local retailer.
