a HeatingInstallation & commissioning
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.
