INTRODUCTION GENERAL NOTES To get the best from your appliance please read these instructions carefully SEALED HEATING SYSTEMS The appliance is fitted to a sealed heating system which is pressurised. Your installer will tell you of the minimum and maximum pressure which must be indicated on the pressure gauge. Check regularly that the pressure is maintained and contact your installer or maintenance engineer if there is a permanent significant drop in pressure.
HOT AND COLD FLOW PUMP The flow of water demanded from both hot and cold service outlets is dependent on the mains supply, it may not be possible in some installations to operate all outlets simultaneously. The pump is set by the manufacturer and must not be adjusted. WATER MAINS FAILURE If there is a failure of the mains water supply then no water will be available at a tap or shower until the mains supply is restored. The appliance will still operate in the central heating mode.
INTRODUCTION GENERAL NOTES Fig. a. BOILER LOCATION AND CLEARANCES This boiler is only suitable for installing internally within a property at a suitable location onto a fixed, rigid non-combustable surface at least the same size of the boiler and capable of supporting the boiler weight. Compartments: Follow the requirements of BS6798 and BS5440 Part 2 and note: Minimum clearances must be maintained. Fig. b. An access door is required for servicing and maintenance of the boiler.

OPERATING THE APPLIANCE SWITCHING THE APPLIANCE ON/OFF Switching on Switch on the appliance at the master switch (I). USING YOUR APPLIANCE The indicator lamp shows green and the display will show the central heating flow temperature, when the appliance is operating in the central heating mode. Note: If the display alternates between -II- & the central heating flow temperature, the condensate trap filling programme is active. If the display shows “t” the tank heat up programme is running.
OPERATING THE APPLIANCE SETTING THE HOT WATER TEMPERATURE The hot water temperature can be set to between approx. 45°C and 65°C using the temperature control The domestic hot water temperature is not shown on the display. Control Setting Water Temperature Anti-clockwise limit approx. 45°C ● approx. 58°C Clockwise limit approx.
OPERATING THE APPLIANCE SUMMER MODE, HOT WATER ONLY With room temperature controller fitted USING YOUR APPLIANCE Turn temperature control on the appliance anti-clockwise as far as the stop. The central heating is now turned off. The hot water function and the power supply for the programmer and thermostat remain switched on. FROST PROTECTION Leave master switch switched on. If the temperature falls to 5°C the boiler will fire to avoid the possibility of freezing.
TIPS ON ENERGY SAVING The boiler is designed to provide a high 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 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.
TIPS ON ENERGY SAVING 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 200mm 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. ENERGY SAVING Curtains Lined curtains, or heavier full length curtains can provide excellent insulation.
TIPS ON ENERGY SAVING Radiators It is advisable to manually adjust all radiator valves every 2-3 months to prevent them from sticking. It is also important that the plastic tops of all valves are always in position and not cracked or damaged so as to prevent accidents. Care should be taken when vacuum cleaning carpets so as to avoid damage to valves and pipework.
MAINTAINING YOUR APPLIANCE Your new Greenstar Highflow 440 gas-fired appliance represents a long term investment in a reliable, high quality product. In order to realise its maximum working life, and to ensure it continues to operate at peak efficiency and performance, it is essential that your boiler receives regular, servicing and maintenance checks from a competent person beyond the initial 2 year guarantee period.
Problem Cause Remedy Desired room temperature is not reached Thermostatic radiator valve(s) set too low Increase thermostatic radiator valve setting(s) Temperature control for CH flow on boiler set too low Increase CH flow temperature control setting Air trapped in heating system Bleed radiators and recharge heating system Desired room temperature exceeded by large amount Radiators are too hot Turn down thermostatic radiator valves / room stat Temperature rises instead of falling Clock is inco
