The Yellow system has been developed to make the installation of Grant boilers both quick and simple, whilst ensuring trouble free operation – even in the most exposed site conditions. The round low level kits feature self-sealing ducts requiring no silicone or tape for joints, and the unique quick-fit clamp arrangement ensures a perfect seal every time. In fact, the new telescopic flue system requires only two simple operations to complete the installation. The kits are compatible with all Grant boilers, (except Outdoor Modules) including condensing models. The flue terminal has a compact design, making it ideal for installations where the visual appearance is important. The new cone design reduces the possibility of condensate, produced in the combustion process, staining external wall surfaces or patio slabs

The Grant Vortex Pro outdoor combination oil boiler features internal frost protection, a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap, together with the conveniently factory-fitted, multi-directional flue - and all of this has been designed to make installation and servicing easier. With larger than normal heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode on central heating and instant hot water production can be maintained.
