GuaranteesThe unique heat exchanger on the Grant Condensing Boiler iscovered by a 5-year guarantee. All other component parts ofthe boiler are guaranteed for 2 years from the date of purchase(excluding consumable items, labour, handling or shipping),subject to being installed in accordance with the manufacturer’sinstructions. On completion of the installation all GrantCondensing Boilers must be commissioned and the boilerpassport returned to Grant Engineering for registration.

After sales serviceFor peace of mind, all Grant Condensing Boilers are backed bya national network of service engineers.

In the unlikely event of a problem occurring, your installershould telephone our customer service department on: (057) 9120089. All images for illustration purposes only.

Grant Vortex Mag-One Magnetic FilterThe Mag-One (Part code: VM01) providesinnovative protection for your Grant Vortex oil-fired boiler and central heating system up to 36kW. Using a simple to install, triple actionfiltration design, the Mag-One filters magnetiteand non-ferrous debris from central heatingsystems with a 12000 gauss neodymiummagnet.

Flue SystemsAll Grant Vortex oil-fired boilers are supplied for connection toeither a ‘stainless steel’ conventional flue, or one of Grant’sEZ-Fit flue options. The flue systems are available as low level,high level or vertical kits, for internal and external applications,and even as unique EZ-Flexi packs designed to enablecondensing boilers to utilise an existing chimney. All our EZ-Fitflues carry the CE mark of approval, are adaptable to anyinstallation, and deliver excellent value for money.

Typical Hot Water Performance26kW Combi** 17 litres per minute at an average temperature of 50°C.Recovery time 4 minutes approx. Based upon 100 litre draw off.

36kW Combi** 20 litres per minute at an average temperature of50°C. Recovery time 3 minutes approx. Based upon 100 litre draw off.

Mains Water PressureMinimum: 2.5bar (36psi). Maximum: 8bar (115psi).** Hot water flow rate is dependent on mains pressure available.Figures based upon an incoming mains water temperature of 10°C.

FuelAll burners are supplied factory set a the stated output for useon standard grade Kerosene – Class C2. Grant CondensingBoilers are not suitable for use with Class D gas oil.

InstallationInstallation must comply with the current Building Regulations.Comprehensive technical information can be found in theinstallation manual, suppllied with every boiler.
