Construction

• Servicing and Maintenance: The GB402 is designed to minimise installation time and effort, and, in the long run, its efficient construction ensures minimised operating costs. The factory-fitted gas-fired burner is tested and set up for optimal and clean combustion. Servicing is also simple. Large inspection apertures make access to components particularly easy and all internal components can be easily cleaned or replaced if necessary.
• Performance and Design: The GB402 has been developed to achieve lower running costs, a reduced carbon footprint and low NOx emissions. This is achieved through the use of a powerful, lightweight and fully insulated cast aluminium heat exchanger. The clean burning, pre-mix burner and intelligent combustion controller enable the GB402 to operate in a wide modulation range of between 20% to 100%, with efficiency up to 110% (NCV).
