Your chimney type
The type of chimney or flue you have usually dictates your choice of fire. To help you establish which
fires are suitable for your home, please use the information and pictures below to identify your chimney.
Don’t worry if you don’t have a chimney though, you can still find the perfect fire for your home!
Throughout this brochure, all fires shown with
this symbol have the advantage of not normally
requiring an air vent* where the air permeability is
greater than 5.0m

Balanced Flue
(No chimney required)
Air for combustion is drawn in through the outer pipe whilst the
inner pipe removes the combustion gases to the exterior of the
property. The twin-walled pipe will exit horizontally through an
external wall. No electric supply is required therefore there is no
sound with this flue system.
Balanced Flue
Brick or Stone Chimney
(Class 1)
The chimney stack rises well above the roofline and is
topped by a traditional chimney pot or gas terminal. This
type of chimney relies on the natural circulation of heated
air to expel the products of combustion up your chimney.
Pre-Fabricated Flues
(Class 1 & 2)
You will see a metal flue cowl on your roof. Some are all
metal whilst others may terminate through a short rectangular
pot (but without a chimney stack). These flues create the
same circulation of heated air as a brick or stone chimney.
Pre-Cast flues
(Class 2)
Many modern homes
have been built with
such flues. You can
readily identify them by either a metal flue cowl or a raised
ridge terminal on your roof. Again, the natural circulation of
heated air expels the products of combustion. Incidentally,
these flues tend to be very shallow in depth so a slimmer
fire is often required. Deep appliances, however, may be
able to be installed with the use of either a spacer kit or
deeper rebate on the fireplace. Please consult your Gazco
retailer for further information.
Conventional Flue
Conventional flue systems are easily recognisable as either
a conventional brick or stone chimney, pre-fabricated or
pre-cast chimney system. Should your home have none of
these at present, it is usually possible to have a
pre-fabricated system installed in your home if required.
Balanced flues work in conjunction with Gazco’s Glass Fronted
gas fires. The appliance is completely sealed from the room into
which it is installed (so there are no draughts and heating
efficiency is increased) and a twin-wall pipe vents directly to an
outside wall.
