2 EcoBlue System 7219708 - 03 (03/17) You have just purchased one of our appliances and we thank you for the trust you have placed in our products. Please note that the product will provide good service for a longer period of time if it is regularly checked and maintained. Our customer support network is at your disposal at all times. The Benchmark Scheme Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers are provided with the correct equipment for their needs, that it is installed, commissioned and serviced in accordance with the manufacturer’s instructions by competent persons and that it meets the requirements of the appropriate Building Regulations. The Benchmark Checklist can be used to demonstrate compliance with Building Regulations and should be provided to the customer for future reference. Installers are required to carry out installation, commissioning and servicing work in accordance with the Benchmark Code of Practice which is available from the Heating and Hotwater Industry Council who manage and promote the Scheme. Visit www.centralheating.co.uk for more information. Building Regulations and the Benchmark Commissioning Checklist Building Regulations (England & Wales) require notification of the installation of a heating appliance to the relevant Local Authority Building Control Department. This can be achieved via a Competent Persons Self Certification Scheme as an option to notifying the Local Authority directly. The Health & Safety Executive operates the ‘Gas Safe Register’, a self- certification scheme for gas heating appliances. This company is a member of the Benchmark initiative and fully supports the aims of the programme. Its aim is to improve the standards of installation and commissioning of central heating systems in the UK and to encourage the regular servicing of all central heating systems to ensure safety and efficiency. Building Regulations require that installations should comply with manufacturer's instructions. It is therefore important that the commissioning checklist is completed by the installer. The relevant section of Building Regulations only relates to dwellings. Therefore the checklist only applies if the appliance is being installed in a dwelling or some related structure. The flowchart opposite gives guidance for installers on the process necessary to ensure compliance with Building Regulations.

7219708 - 03 (03/17) EcoBlue System 13 Safety 2 2.3 Specific Safety Instructions 2.3.1 Handling General • The following advice should be adhered to, from when first handling the boiler to the final stages of installation, and also during maintenance. • Most injuries as a result of inappropriate handling and lifting are to the back, but all other parts of the body are vulnerable, particularly shoulders, arms and hands. Health & Safety is the responsibility of EVERYONE. • There is no ‘safe’ limit for one man - each person has different capabilities. The boiler should be handled and lifted by TWO PEOPLE. • Do not handle or lift unless you feel physically able. • Wear appropriate Personal Protection Equipment e.g. protective gloves, safety footwear etc. Preparation • Co-ordinate movements - know where, and when, you are both going. • Minimise the number of times needed to move the boiler - plan ahead. • Always ensure when handling or lifting the route is clear and unobstructed. If possible avoid steps, wet or slippery surfaces, unlit areas etc. and take special care on ladders/into lofts. Technique • When handling or lifting always use safe techniques - keep your back straight, bend your knees. Don’t twist - move your feet, avoid bending forwards and sideways and keep the load as close to your body as possible. • Where possible transport the boiler using a sack truck or other suitable trolley. • Always grip the boiler firmly, and before lifting feel where the weight is concentrated to establish the centre of gravity, repositioning yourself as necessary. See the ‘Installation’ section of these instructions for recommended lift points. Remember • The circumstances of each installation are different. Always assess the risks associated with handling and lifting according to the individual conditions. • If at any time when installing the boiler you feel that you may have injured yourself STOP !! DO NOT ‘work through’ the pain - you may cause further injury. IF IN ANY DOUBT DO NOT HANDLE OR LIFT THE BOILER - OBTAIN ADVICE OR ASSISTANCE BEFORE PROCEEDING !

20 EcoBlue System 7219708 - 03 (03/17) 4 Description of the Product 4.2 Operating Principle 4.2.1 Central Heating Mode 1. With a demand for heating, the pump circulates water through the primary circuit. 2. Once the burner ignites the fan speed controls the gas rate to maintain the heating temperature measured by the temperature sensor. 3. When the flow temperature exceeds the setting temperature, a 3 minute delay occurs before the burner relights automatically (anti-cycling). The pump continues to run during this period. 4. When the demand is satisfied the burner is extinguished and the pump continues to run for a period of 3 minutes (pump overrun). 4.2.2 Boiler Frost Protection Mode 1. The frost protection mode is integral to the appliance and functions as long as there is power to the boiler, as indicated by the standby signal . 2. With the boiler in ‘On’ mode and when the boiler temperature falls below 5°C the boiler will fire until a temperature of 30°C is reached. 3. Further protection can be incorporated by using a system frost thermostat. 4.2.3 Pump Protection 1. This activates once a week if there has been no demand. The pump runs for 30 seconds to prevent sticking. Boiler Schematic Layout To operate the boiler must be set so that the symbol is displayed. Press the button to display the symbol. N.B.

All recirculatory water systems will be subject to corrosion unless they are flushed and an appropriate water treatment is applied. To prevent this, follow the guidelines given in BS 7593 “Treatment of Water in Domestic Hot Water Central Heating Systems” and the treatment manufacturers instructions. 2. Treatment must involve the use of a proprietary cleanser, such as Sentinel X300 or X400, or Fernox F3 and an inhibitor such as Sentinel X100 or Fernox MB-1. 3. Full instructions are supplied with the products. For further information contact Sentinel (0800 389 4670) or Fernox (0870 870 0362). Failure to flush and add inhibitor to the system will invalidate the appliance warranty. 4. It is important to check the inhibitor concentration after installation, system modification and at every service in accordance with the inhibitor manufacturer’s instructions. (Test kits are available from inhibitor stockists.) 5. Complete the label supplied with the inhibitor and attach to the inside of the boiler case. Detail of system treatment should be added for future reference. 6. For information or advice regarding any of the above contact Baxi Customer Support 0344 871 1525. 5.2.7 Expansion Vessel (CH only) 1. The appliance expansion vessel is pre-charged to 1.0 bar. Therefore, the minimum cold fill pressure is 1.0 bar. The vessel is suitable for correct operation for system capacities up to 100 litres (155 litres for 32 model). For greater system capacities an additional expansion vessel must be fitted. For GB refer to BS 7074 Pt 1. For IE, the current edition of I.S. 813 “Domestic Gas Installations”. 2. Checking the charge pressure of the vessel - to check the charge accurately ensure the system is cold. It is also necessary to relieve the pressure by draining the boiler. Using a suitable gauge check the pressure at the valve on the underside of the vessel. Adjust the pressure as required and repressurise the system.

7219708 - 03 (03/17) EcoBlue System 29 Before Installation 5 5.3.5 Condensate Drain FAILURE TO INSTALL THE CONDENSATE DISCHARGE PIPEWORK CORRECTLY WILL AFFECT THE RELIABLE OPERATION OF THE BOILER. CAREFUL CONSIDERATION MUST BE GIVEN TO THE POSSIBILITY OF THE PIPEWORK BEING SUBJECT TO FREEZING CONDITIONS AND APPROPRIATE MEASURES TAKEN TO PREVENT BLOCKAGE. CORRECT INSTALLATION IN ACCORDANCE WITH THIS SECTION WILL CONSIDERABLY MINIMISE THE LIKELIHOOD OF BLOCKAGE AND SUBSEQUENT BOILER LOCK-OUT. A CONDENSATE DISCHARGE PUMP AND PIPE ‘TRACE HEATING’ ARE AVAILABLE AS ACCESSORIES - see paragraphs 5.3.6.12 to 5.3.6.15 for further details. The condensate discharge pipe MUST NOT RISE at any point along its length. There MUST be a fall of AT LEAST 2.5° (50mm per metre) along the entire run EXCEPT when employing a suitable condensate pump in basement and cellar or similar applications. The boiler condensate trap incorporates a seal of 75mm, therefore it is unnecessary to install an air break and trap in the discharge pipework. 1. The condensate outlet will accept 21.5mm (3/4in) plastic overflow pipe. It is strongly recommended that this discharges internally into the household drainage system. Where this is not possible, discharge into an outside drain is permissible providing every possible precaution is taken to prevent freezing. 2. Ensure the discharge of condensate complies with any national or local regulations in force. BS 6798 & Part H1 of the Building Regulations give further detailed guidance. 3. The discharge pipe should be run in a proprietary drain pipe material e.g. PVC, PVC-U, ABS, PVC-C or PP. 4. Metal pipework is NOT suitable for use in condensate discharge systems. 5. The pipe should be a minimum of 21.5mm diameter and must be supported using suitably spaced clips of the correct design to prevent sagging. 6. It is advisable that the full length of condensate pipe is run internally and preferably be less than 3 metres. 7. Internal runs greater than 3 metres or runs in cold areas should use 32mm waste pipe. 8. External runs MUST be a MINIMUM of 32mm and fully insulated with material suitable for external use. Examples are shown of the following methods of termination:- i) to an internal soil & vent pipe ii) via an internal discharge branch (e.g. sink waste) downstream of the trap iii) to a drain or gully iv) to a purpose made soakaway v) pumped into an internal discharge branch (e.g. sink waste) downstream of the trap vi) pumped into an external soil & vent pipe vii) to a drain or gully with extended external run & trace heating It is strongly recommended to discharge internally into the household drainage system. If connecting to a rain water drain, that drain MUST discharge into a foul drain. 21.5mm 32mm Insulation 2.5° Minimum fall i) Termination to an internal soil and vent pipe 450mm min* 50mm per metre of pipe run *450mm is applicable to properties up to 3 storeys.

30 EcoBlue System 7219708 - 03 (03/17) 5 Before Installation 9. If the boiler is fitted in an unheated location the entire condensate discharge pipe should be treated as an external run and sized and insulated accordingly. 10. In all cases discharge pipe must be installed to aid disposal of the condensate. To reduce the risk of condensate being trapped, as few bends and fittings as possible should be used and any burrs on cut pipe removed. 11. When discharging condensate into a soil stack or waste pipe the effects of existing plumbing must be considered. If soil pipes or waste pipes are subjected to internal pressure fluctuations when WC's are flushed or sinks emptied then back- pressure may force water out of the boiler trap and cause appliance lockout. 12. A boiler discharge pump is available which will dispose of both condensate & high temperature water from the relief valve. It has a maximum head of 5 metres. Follow the instructions supplied with the pump. 13. Condensate Drain Pipe ‘Trace Heating’ Elements are available in various lengths, 1, 2, 3 & 5 metres. Where the drain is between 3 & 5 metres a 5 metre kit can be used and “doubled back” upon itself. 14. It is possible to fit the element externally on the condensate drain or internally as detailed in the instructions provided. 15. The fitting of a ‘Trace Heating’ Element is NOT a substitute for correct installation of the condensate drain. ALL requirements in this section must still be adhered to. Boiler 2.5° Minimum fall iii) Termination to a drain or gully Boiler 500mm min 2.5° Minimum fall iv) Termination to a purpose made soakaway Holes in the soak-away must face away from the building 50mm per metre of pipe run 50mm per metre of pipe run Further specific requirements for soakaway design are referred to in BS 6798.

When the component has been changed recommission the boiler as described in Section 7. Always examine any seals or gaskets, replacing where necessary. The Case Front Panel MUST seal effectively against the boiler side panels. 1. For reasons of safety and economy, it is recommended that the boiler is serviced annually. Servicing must be performed by a competent person in accordance with B.S. 7967-4. 2. After servicing, complete the relevant Service Interval Record section of the Benchmark Commissioning Checklist at the rear of this publication. During routine servicing, and after any maintenance or change of part of the combustion circuit, the following must be checked:- • The integrity of the complete flue system and the flue seals by checking air inlet sample to eliminate the possibility of recirculation. O2 20.6% & CO2 < 0.2% • The integrity of the boiler combustion circuit and relevant seals. • The operational gas inlet pressure and the gas rate as described in Section 7.5.1. • The combustion performance as described in ‘Check the Combustion Performance’ below. 3. Competence to carry out Checking Combustion Performance B.S. 6798 ‘Specification for Installation & Maintenance of Gas Fired Boilers not exceeding 70kWh’ advises that:- • The person carrying out a combustion measurement should have been assessed as competent in the use of a flue gas analyser and the interpretation of the results. • The flue gas analyser used should be one meeting the requirements of BS7927 or BS-EN50379-3 and be calibrated in accordance with the analyser manufacturers’ requirements. • Competence can be demonstrated by satisfactory completion of the CPA1 ACS assessment, which covers the use of electronic portable combustion gas analysers in accordance with BS 7967, Parts 1 to 4. 4. Check the Combustion Performance (CO/CO2 ratio) Set the boiler to operate at maximum rate as described in Section 7.4. 5. Remove the plug from the flue sampling point, insert the analyser probe and obtain the CO/CO2 ratio. This must be less than 0.004. If the combustion reading (CO/CO2 ratio) is greater than this, and the integrity of the complete flue system and combustion circuit seals has been verified, and the inlet gas pressure and gas rate are satisfactory either:- • Perform the ‘Standard Inspection and Maintenance’ (Section 10.2) & re-check. • Perform ‘Setting the Gas Valve’ (Section 10.3.20) & re-check. • Replace and set the gas valve (Sections 10.3.19 & 20) & re-check.
