Your home...

The type of chimney or flue you have usually dictates your choice of fire. To help you understand which fires are suitable for your home, please use the following information and pictures 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!

Once you have identified your chimney (or confirmed you do not have one), take note of the symbol that represents this, as this will be used throughout the brochure to represent the fire or fires that are suitable for installation in your home. You may also want to utilise the fold-out key at the back of this brochure to quick reference any symbols. Please check with your local Gazco retailer that your flue and fireplace opening are suitable for your fire choice.

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.

An Integral Powered Flue fire is an open fronted gas appliance with an electronically driven fan system mounted directly behind it on an external wall. When the fire is ignited the fan switches on automatically, expelling the products of combustion through a short, horizontal metal flue to the outdoors.

Brick/Stone Chimney

(Class 1) 1

Conventional chimneys are easily recognisable. The 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) 2

Balanced Flue

(No chimney required) BF

Balanced flues work in conjunction with 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. Air for combustion is drawn in through the outer pipe whilst the inner pipe removes the combustion gases to the exterior of the property. Depending on the fire selected, the twin-walled pipe may exit horizontally through an external wall or vertically through the roof. No electric supply is required; therefore there is no sound with this flue system.

Powered Flue

(No chimney required) PF

This works in a very similar manner to the Integral Powered Flue. However, the main benefit is that, instead of a short, straight-through-the-wall flue, you can have much longer flue runs and up to three bends in the flue. This means your fire does not have to be installed against an external wall so it can be located in more rooms around your home.

Electric Fires

(No chimney required)

Gazco produce an excellent selection of electric Riva fires and the electric Stilo inset fire which do not, of course, require a chimney or flue of any kind.

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.
