[. . . ] Worcester Bosch has led the field in innovative appliance design and performance for more than 40 years. This heritage means all products are of exceptional quality and proven reliability. The Greenstar range in particular is extremely energy efficient, converting up to 97% of gas consumed into heat, offering you economical running costs and value for money. It sits in SEDBUK Band A, and is therefore amongst the top energy rated appliances available. [. . . ] If the appliance is fitted into a cupboard or a compartment is built around the appliance after installation, then the compartment must be separated from the boiler space by a perforated non-combustible partition as described in BS 6798. Notwithstanding the requirements of BS 6798 and BS 5440 there is no need for ventilation openings to be provided in the compartment because of the low heat loss from the appliance casing, if the clearances shown are maintained. Do not operate the appliance if the flue terminal fitted on the outside wall or roof is obstructed or damaged. PUMP ANTI-SEIZURE If there has been no heating demand for 24 hours the boiler will run the system pump for a few seconds to reduce the possibility of pump seizure during long periods of inactivity, which is usually more frequent during the summer months.

The indicator light shows blue · The boiler runs for 15 minutes at minimum heating output to fill the condensate trap, the display (K) alternates between "-II-" and the central heating flow temperature. This occurs every time the mains supply has been interrupted. Switching off B Switch off the appliance by pressing the master switch. SETTING THE CENTRAL HEATING TEMPERATURE B Turn the central heating temperature control to the desired level, between 40 °C and 90 °C. 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 for heat reduces. The technical term for this process is modulating control. Modulating control reduces temperature fluctuations and provides even distribution of heat throughout the home. This means that the boiler may stay on for relatively long periods but will use less gas than an appliance that continually switches on and off. Central heating systems with room thermostats/thermostatic radiator valves The central heating control on the boiler should be set to the maximum rated temperature of the central heating system. The temperature of each room can be set individually (except primary room with the room thermostat) using the thermostatic radiator valves. Roof insulation Around 30% of the heat loss from a property is through the roof. Replace any old insulation with new insulation, preferably of around 200 mm thickness or more. Window frames Single glazed windows, particularly those with steel frames, can lose a great deal of heat. Consideration should be given to replacement with PVCu or wooden framed double glazed units. Curtains Lined curtains, or heavier full length curtains can provide excellent insulation. However, always ensure that the curtains do not drape over radiators.
