5.2 Use of the control panel 5.2.1 Using the control panel Important OpenTherm controller.Your installer will advise you when this type of control is connected to the boiler. If so, any change to the boiler settings (e.g. heating temperature) must be made using the OpenTherm controller not the boiler control panel. Please consult the user manual for the OpenTherm controller. To increase or decrease the boiler temperature: 1. Turn the control knob with the symbol over it clockwise to increase the boiler set temperature. The set temperature will be shown on the display screen. 2. Turn the control knob with the symbol over it anticlockwise to decrease the boiler temperature. The temperature will be shown on the display screen. To reset the boiler: 1. Press the Reset button for approximately 1 second, holding the button for more than 2 seconds the boiler will not reset. (see List of error codes, page 21.) 5.3 Shutdown Isolate the mains power supply at the fused spur unit. Isolate the gas supply at the boiler valve. Protect the boiler from frost. Important The boiler is not protected against frost once it has been shut down. Important If it is anticipated that the boiler will not be used for a long period or the property is to be unoccupied, it is advised to drain the system if the electricity and gas supplies are to be turned off. Your installer will be able to offer advice. 5.4 Frost protection Where possible, draining the system should be avoided. If the system is to be unused during winter months several precautions must be taken: Any parts of the system that are in unheated areas of the dwelling should be fitted with a device such as a pipe thermostat or frost thermostat. Power must remain supplied to the boiler and controls. Gas must remain supplied to the boiler. The boiler pump will operate if the system temperature drops below 7°C. If the temperature falls to 4°C the burner will ignite and remain lit until the temperature reaches 10°C. At this temperature the burner will extinguish but the pump will continue to operate for 15 minutes. This feature will protect the boiler and to some extent adjacent parts of the system but additional devices must be incorporated to guarantee frost protection.

6 Maintenance 6.1 General The boiler must be serviced annually in accordance with the Installation and Service Manual and the relevant section of the Benchmark Service Record completed in order to maintain the warranty. Important Taking out a maintenance contract is recommended. Caution Maintenance operations must be performed by a qualified competent person. Use only Potterton genuine spare parts. The painted panels should be wiped with a damp cloth and then dried completely. DO NOT USE ABRASIVE CLEANING AGENTS. 6.2 Maintenance instructions The central heating system should be checked regularly. Proceed as follows: 1. Check the water pressure in the central heating system. Important If the water pressure is lower than 0.7 bar, the system must be topped up. See Re-pressurising the system. Important If the water pressure drops below 0.5 bar the boiler will not work. 2. Check radiators for leaks and (especially in damp areas) for rust. 3. Open and close the radiator valves several times a year to ensure they can still be rotated. Caution Only a qualified installer may clean the inside of the boiler. 6.2.1 Re-pressurising the system If the water pressure is too low, the system must be re-pressurised. The normal operating water pressure is between 1 and 2 bar. If the pressure exceeds 3 bar the safety pressure valve will operate and a fault is indicated. Ensure that the filling loop is disconnected if it is of a temporary type. Contact your installer. 6 Maintenance 17

It may be necessary to repressurise the system occasionally (when the water pressure falls below 0.7). A filling device (the filling loop) will be fitted on the system. This may be on the boiler itself, or on pipework near to the boiler. Important If the water pressure requires regular re-pressurising a fault or leak is indicated. Seek advice from your installer. Depending on which filling loop is fitted, a temporary filling loop consists of two isolating taps and a separate filling pipe with connection fittings. Only when repressurising should the filling pipe be connected between the two taps. Ensure that the nuts on the pipe ends are tightened onto the taps. 1. Fully open one of the taps first, and then while watching the pressure gauge, carefully open the second tap. Important The system pressure is shown at all times on the pressure gauge and can be viewed on the display when there is power to the boiler. 2. When the figures on the display or needle on the pressure gauge indicate between 1 and 1.5 bar turn both taps off. 3. Disconnect the filling pipe from the taps (a small amount of water may be present) and remove it. Keep the pipe in a safe place for future use. 4. If blanking caps are available fit them to the taps. See Go to the "How to videos" section of the "Information & advice" page at www.baxi.co.uk for further details. 5. When the correct pressure is restored the boiler will reset automatically.

6.3 Venting the installation If any air is present in the appliance or system it must be removed in order to prevent nuisance noises that may occur during heating or when drawing off hot water. Proceed as follows: 1. Open the valves of all the radiators connected to the system. 2. Set the room thermostat to the highest possible temperature and any timers to ‘ON’. 3. Wait until the radiators are warm. 4. Switch off the boiler. 5. Vent the radiators. Work from the lowest radiator in the property. 6. Open the bleed vent with the key, keeping a cloth pressed against the vent. 7. Wait until water comes out of the bleed vent and then close. Warning The CH water in the radiators will still be hot. 8. Switch the boiler on. 9. After venting, check that the water pressure in the system is still adequate. Important If the water pressure is lower than 0.7 bar, the water must be topped up. If necessary repressurise the system (recommended pressure between 1 and 1.5 bar when cold). 10. Reset the room thermostat to the desired temperature. The purpose of the function is to remove as much air as possible from the heating system. 1. Turn off the power to the boiler and rotate the CH control knob fully anticlockwise. 2. Turn on the power to the boiler. The display shows "000" . 3. Turn the CH control knob ( ) 1/4 turn clockwise twice in quick succession (within 2 seconds). 4. Display shows "312" while de-aeration is taking place (approximately 7 minutes). 5. When de-aeration has completed, the display will show the primary flow temperature and the CH ( ) symbols.

Caution If the system is drained (even partly, when replacing a radiator for example) the de-aeration function must be repeated. Also the inhibitor concentration must be checked and replenished if necessary. 6.4 Draining the installation It may be necessary to drain the central heating system if radiators need to be replaced, if there is a major water leak or if there is a risk of freezing. Proceed as follows: 1. Open the valves of all the radiators connected to the system. 2. Switch off the boiler's electrical connection. 3. Wait approximately ten minutes, until the radiators feel cold. 4. Connect a drain hose to the lowest draining point. Place the end of the hose in a drain or at a place where drained pipe water will not cause any damage. 5. Open the central heating system fill/drain valve. Drain the installation. Warning The water may still be hot. 6. Close the drain valve when no more water comes from the draining point. Important After draining the system, the concentration of corrosion inhibitor and antifreeze agent may be extremely diluted - check with your installer.

10 Environmental 10.1 Energy saving Tips on saving energy: Do not cover radiators. Do not hang curtains in front of radiators. Install reflective panels behind the radiators to prevent heat loss. Insulate the pipes in rooms that are not heated (cellars and lofts). Install loft insulation & double glazing. Use draught excluders where necessary. Upgrade any older boiler external controls. Turn down room thermostats by 1°. Turn off radiators in rooms not in use. Do not run hot (or cold) water pointlessly. Fit a water-saving shower head to save up to 40 % energy. Take showers rather than baths. A bath consumes twice as much water and energy. 10.2 Room thermostats and settings Various models of room thermostat are available. The thermostat type and setting affect the total energy consumption. A few tips: A modulating thermostat in combination with thermostatic radiator valves saves energy and offers considerable comfort. This combination gives you flexibility with the temperatures. Do not fit thermostatic radiator valves in the room in which the room thermostat is installed. Completely closing and opening thermostatic valve radiators causes undesirable temperature fluctuations. Open and close thermostatic valves in small steps. Lower the thermostat to around 20°C. This reduces heating costs and energy consumption. Lower the room thermostat temperature temporarily if opening windows to air the rooms. If you are using an ON/OFF type thermostat, reduce the water temperature value in summer (e.g. 60°C in summer and 80°C in winter). When setting an hourly programmable thermostat, consider days when you are absent or on holiday. Electricity production and energy savings reach their optimum level with a programmed and activated timer programme. 10 Environmental 25
