TIPS ON ENERGY SAVING 7 TIPS ON ENERGY SAVING HEATING ECONOMICALLY DRAUGHTS The boiler is designed to provide a level of comfort while keeping gas consumption and the resulting environmental effect as low as possible. The gas supply to the burner is controlled according to the level of demand for heat. The boiler continues to operate with a low flame if the demand of heat reduces. The technical term for this is modulating control.
YOUR GUARANTEE 8 YOUR GUARANTEE This boiler has a guarantee against faulty materials or workmanship for a period of two years from the date of installation subject to the following terms and conditions: • During the period of this guarantee any components of the boiler which are proven to be faulty or defective in manufacture will be exchanged or repaired free of charge by Bosch Thermotechnology Ltd.
GLOSSARY 9 GLOSSARY Central heating systems All radiators must be heated at an even rate. If the top of a radiator is at a lower temperature than the bottom then it should be bled by releasing air through the bleed screw at the top of the radiator. Ask your installer to show you how this is done. This boiler is fitted to a sealed system. Should water leaks be found or if excessive bleeding is required, then a service engineer must be contacted to inspect the installation and rectify any fault.
