This flue system is designed for use in combination with condensing heating appliances. The flue pipe is centred in the outer pipe by the CONNEXT® X7-connection. This system is available in concentric diameter sizes 60/100, 80/125, 100/150 and 110/160 mm. Colour of outer pipe is white (RAL 9016). CE marked to the European standard EN 14471.
Safe with concentric
That is Cox Geelen’s vision into which this new innovative system perfectly fits. Carbon monoxide (CO) is an underestimated and unrecognized danger. Carbon monoxide poisoning is often caused by modern heating appliances. To reduce the risk of such poisoning, it is advisable to install a concentric flue gas system. In the unlikely event of a leak in the flue gas pipe, the flue gases entering the combustion air supply pipe are routed to the combustion heater. An excessively high content of recirculated flue gas will cause the boiler to shut down.

Fire-resistant wall plates
Recently Cox Geelen introduced round fire-resistant wall plates with integrated fireproof plate and fire protection seal. These innovative CoxDENS® wall plates are available for connection to flexible as well as concentric flue gas systems. These revolutionary wall plates neatly cover an opening in the wall and also provide a fire and carbon monoxide safe situation in the home. Why round? Mounting can not go crooked and the slope of 3° is included in the design. read more
