This occurs every time the mains supply has been interrupted. Switching off ▶ Switch off the boiler by pressing the ON/OFF button.
Operating the boiler 3.3 SETTING THE CENTRAL HEATING TEMPERATURE ▶ Turn the central heating temperature control to the desired level, between approximately 35 °C and 90 °C. When the burner is lit, the burner indicator light [1] underneath the ON/OFF button shows green. 1 min 6 720 812 178-03.1O Fig. 3 Position Central heating temperature 1 approx. 35 °C 2 approx. 43 °C 3 approx. 50 °C 4 approx. 60 °C 5 approx. 67 °C 6 approx. 75 °C max Table 2 approx.

Maintenance 4 MAINTENANCE Your new Greenstar CDi Classic System ErP gas-fired appliance represents a long term investment in a reliable, high quality product. If you would like to know more about a Worcester Bosch service contract, please tick the appropriate box on your warranty registration card.
Maintenance 4.2 ERROR CODES When calling Worcester, Bosch Group, you may be asked for the error code. This Table is for you to help identify the possible cause of the fault. ▶ Do not try to rectify any of the faults listed below by yourself. ▶ Contact British Gas or a competent, qualified engineer (Gas Safe registered personnel). Error code Description b1 Code plug not detected. C6 Fan speed too low. E9 Safety temp. limiter in CH flow has tripped. EA Flame not detected.
General notes 4.3 EXTREME COLD WEATHER In some instances where the condensate pipe work is run externally or in an unheated area, such as a garage, the condensate pipe work can be at risk of freezing, even if well insulated. The Greenstar CDi Classic System ErPcontains a larger internal condensate siphonic trap, but care should be taken in the location of a condensate pipe. A frozen/blocked condensate pipe will cause the boiler to shut down.
Fault or Breakdown ▶ Do not restrict this space with the addition of cupboards, shelves etc. around or next to the boiler. VENTILATION This is a room sealed boiler and does not require any air for combustion from inside the property. If a compartment is built around the boiler after installation, then this must be carried out as described in the Installation Manual. CAUTION: Risk of damage to the boiler. ▶ Do not operate the boiler if the flue terminal is obstructed or damaged in any way.
Tips on energy saving 7 TIPS ON ENERGY SAVING HEATING ECONOMICALLY 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.
Environment / disposal 8 ENVIRONMENT / DISPOSAL Environmental protection is a fundamental corporate strategy of the Bosch Group. The quality of our products, their economy and environmental safety are all of equal importance to us and all environmental protection legislation and regulations are strictly observed. We use the best possible technology and materials for protecting the environment taking account of economic considerations.
Glossary 10 GLOSSARY PLUMING AND CONDENSATE DRAIN This is a condensing boiler and the flue terminal will, at times give out a plume of water vapour. This is quite normal. The boiler produces condensate which is discharged regularly by a syphon within the boiler via a plastic pipe to a drain. This pipe must not be blocked or altered in any way.
