Installation must comply with the current Building Regulations. As with all oil-fired appliances, Grant Condensing Boilers require commissioning at the time of Installation. This simple process ensures that the boiler is working at peak efficiency which, in turn, will result in lower running costs and long term reliability. Annual maintenance is also made easy by Grant’s cleverly designed front service access to both burner and all the internal serviceable parts. This feature enables Grant Condensing Boilers to be fitted neatly and unobtrusively within either the kitchen, boiler house, or utility room environment. Comprehensive technical information can be found in the installation manual.
All burners are supplied factory set at the stated output for use on standard grade Kerosene — Class C2. Grant Condensing Boilers are not suitable for use with Class D gas oil.

EZ-Fit Flue System
All Grant outdoor combi boilers are supplied for connection to one of Grant’s EZ-Fit Flue options (modules come supplied with flue terminals). EZ-Fit Flue Kits feature self-sealing ducts which reduce installation time and ensure a perfect seal without the need for mastic or tape. 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 enable condensing boilers to utilise an existing chimney.
Condensing boilers operate at extremely high efficiency levels, producing cool flue gas temperatures, resulting in a ‘plume’ of vapour being visible at the flue terminal. This plume (stream) is a normal condition of condensing boiler operation and indicates that the appliance is working efficiently. As an alternative to a low level balanced flue kit, high level, or vertical kits are available, which moves the plume to a higher level.
The terminal should be positioned so as to avoid products of combustion accumulating in stagnant pockets around the building or entering into buildings. Care should also be taken that plume from the gases does not cause a nuisance.
The unique heat exchanger on the Grant Condensing Boiler is covered by a 5-year guarantee. All other component parts of the boiler are guaranteed for 2 years from the date of purchase (excluding consumable items), subject to being installed in accordance with the manufacturers instructions.
On completion of the installation all Grant Condensing Boilers must be commissioned and the boiler passport returned to Grant Engineering for registration.
After sales service
For peace of mind, all Grant Condensing Boilers are backed by a national network of service engineers.
