EES : no more restriction ! BG have a world-wide patent on their exclusive extraction system; it sets the installation of your fireplace free from all the traditional rules for installing exhaust ducts. It enables duct lengths to be up to 50m long, going down or in any direction! The EES reduces the diameter of pipes to 130mm. The installation will be much easier! The EES comes as standard for all the models in the gas range, compact and quiet, it is easy to install, to maintain and to connect! Gas-burning fireplaces with EES are easy to use and come with a fully programmed remote control. Argos and Argos Plus models are supplied with a 750 m 3 /hr turbine. The EES ‘bi-flow’ The EES Bi-Flow system allows the installer to separate the route of combustion air ducting, from the route of waste products ducting. Key advantages of this system are ; - This means that combustion air can be provided directly with plastic ducting, which reduces cost. - The ducting for waste products is reduced to 80mm, which is less expensive and much easier to install. Overall, the ‘Bi-flow’ increases installation possibilities and reduces installation costs. The collective EES Once again, BG is revolutionising the normal principles that govern the installation of gas fires with the collective EES, which allows you to switch on up to 15 appliances through a single outlet pipe, which is ideal for example for new buildings. This exclusive system enables you to have a single central pipe rather than 15 separate pipes! Needless to say, the cost has been brought down substantially, while installation turns out to be much faster and simpler.
