Further more, in accordance with BS 6644: 2011 system with an input greater than 70kW (nett), an automatic water replenishment unit shall be installed to automatically replenish any lost or evaporated water. Please refer to BS 6644: 2011 for allowable water replenishment methods for use with sealed/pressurized heating systems. For information on a comprehensive range of pressurization units that comply with current British Standards and WRAS Regulations, please contact MHG Heating Ltd Sales. 18 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 8.1 Expansion Vessel In accordance with BS 6644: 2011, WRAS Regulations, and Local Authority Water Regulations, as applicable, the installer shall install a suitably sized, and approved, Expansion Vessel to ensure that the water capacity of the system has ample expansion capacity. The location of the expansion vessel shall only be isolatable from the system via a Lockable Type Service Valve, which shall be locked in the OPEN position, to prevent accidental isolation. Furthermore, a drain facility should be provided adjacent to the expansion vessel to aide the routine maintenance, overhaul, of the vessels Air Pressure setting. For information on a comprehensive range of expansion vessels that comply with current British Standards and WRAS Regulations, please contact MHG Heating Ltd Sales. 9.0 System Water Quality Water Treatment, System Cleaning (BS 7592: 2006) The entire primary system MUST be thoroughly cleaned and flushed to remove debris, flux residues, etc. before opening the boiler isolation valves & flooding the boiler. Particular care must be taken where the Ultrabox boiler is being retro-fitted into an old/existing system, as system silt or magnetite can be very damaging to the new boiler. Following cleaning and flushing the system MUST be dosed with a good quality water treatment to prevent corrosion and the formation of scale. FAILURE TO OBSERVE THESE REQUIREMENTS WILL RENDER THE WARRANTEE ON THE APPLIANCE VOID. Cleaning, flushing and water treatment must be carried out in accordance with the requirements of BS 7593:1992, prior to commissioning the boiler. Repeated draining and refilling of the system, without replenishment of water treatment, must be avoided, as this is very damaging to the boiler. The boiler must not operate without the system water being correctly and adequately treated, and maintained, with an appropriate level of corrosion inhibitor. For specific guidance on water treatment, direct contact is advisable with:- Fernox 2 Genesis Business Park Albert Drive Sheerwater Woking Surrey GU21 5RW P:0330 100 7750 F: 0330 100 7751 E: [email protected] W: www.fernox.com 9.1 Care With The Use of Solder Flux The Ultrabox range has heat exchangers fabricated from Stainless Steel. It is most important that the compatibility of any flux is checked with the supplier before use, and that any flux manufactures recommendations are strictly followed with regards to use in conjunction with Stainless Steel. If you are applying any of the Ultrabox Range to a system where the water quality cannot be cleansed or treated please consider installing a system separation plate heat exchanger to ensure absolute separation of the system water and the boiler water. Please refer to our website for further details on our matched brazed and gasketed plate heat exchanger range. 19 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 10.0 Boiler Controller Label 1 2 3 4 5 6 7 8 9 10 Symbol Description Heating Mode Select Button Show Information Manual (Hand) Emission Test Mode Accept Setting (Select) Navigation and Setting (Rotary) Escape Button Reset Button Service Connector for BSB data BUS Hot Water Mode Select Description Automatic Mode Continuous Operation (Day Mode) Reduced Operation (Night Mode) Frost Protection Mode Ongoing Process - Wait Battery Requires Changing Holiday Mode Active Heating Circuit 1/2/3 Active Maintenance / Special Operation Error Alarm Activated Burner in Operation (Burner Stage) INFO Level Activated PROG Level Activated ECO Function Activated (Heating Temporarily Switched Off) 20 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 10.1 Accessing Controller Parameters To access the controller parameter menu, from the standard home screen, press the OK button once then press and hold the INFO button for 5 seconds until the lower section of the screen changes.

commissioning of the unit please ensure that the system water has been cleansed and treated with a suitable inhibitor as detailed in Filling the system and system water quality. A tightness test must be carried out from the appliance to the first isolation valve (or further if connected to untested pipe work). 11.2 Combustion System Commissioning The combustion of the appliance must be commissioned by a suitably qualified engineer using a flue gas analyser. The following steps must be followed to ensure the correct and complete commissioning of the combustion system has taken place. 1: On completion of a tightness test the boiler must first be fired and tested in Maximum output. 2: To operate the boiler in maximum output the MODE selection butting is to be pressed and held for at least 3 seconds. 'Control functio stop' will appear on the display. 3: Press the INFORMATION button once, the screen will now display the modulation rate of the boiler as %. 4: Adjust the setting to 100% using the NAVIGATION button, then press OK to set. 5: Set the CO2 value by turning the throttle screw shown in the image below. Anticlockwise adjustment increases the CO2 reading Clockwise adjustment decreases the CO2 reading 6: Adjustments are to be done in small increments and the combustion allowed to stabalise before readjusting. 7: Once the correct CO2 valve has been set at Maximum output press the OK button, the 100% will flash. Use the NAVIGATION button to alter the value to read 0%. Press the OK button to set the boiler into Minimum output. 8: Set the CO2 value by adjusting the zero point screw shown below. Anticlockwise adjustment decreases the CO2 reading Clockwise adjustment increases the CO2 reading 9: Adjustments are to be done in small increments and the combustion allowed to stabalise before readjusting. 10: Once the correct CO2 valve has been set at Minimum output the controller is returned to normal operation by pressing and holding the MODE selection button for at least 3 seconds. 53 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd A flue gas analyser must be used to ensure that the correct combustion setting are achieved. This is undertaken by inserting the analyser’s probe in to plugged hole within the flue collector of the appliance or in the tapping in the flue immediately after the boiler outlet. The combustion setting required for all Ultrabox appliances are as detailed in the following tables. Model 1000 Min. Max. CO2 Emissions (G20) % 9.1 9.4 CO Emissions (G20) ppm 6 22 1125 Min. 9.2 7 Max. 9.4 28 54 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 12.0 Routine Inspection and Servicing Maintenance should be carried out in the appliance on at least an annual basis dependent on usage. during the servicing of the appliance any faults should be identified and remedied immediately to avoid further damage to the system. The boiler should be inspected only by a qualified service engineer. in addition, the maintenance and care of the boiler designated and explained on the following pages must be performed to ensure maximum boiler efficiency and reliability. Failure to service and maintain the boiler as detailed could lead to equipment premature failure. 13.0 Maintenance Procedure During maintenance the following points should be checked and/or part must be inspected and maintained. Before undertaking any work on the appliance notes and comments from the customer should be taken and investigated if any faults are reported. Servicing of heat exchanger; 1: Ensure electrical supply to boiler is isolated and made safe. Ensure that gas supply to boiler is isolated. 2: Allow time for the boiler to cool to a safe temperature to handle if it has been firing. 3: Remove the case from the boiler to allow access to the internal components. 4: Disconnect the internal gas pipe from the inlet pipe. 5: Disconnect the earth lead, HT cap and Lead from the ignition electrodes. Also removing rectification lead from probe 6: Disassemble the burner by removing the nuts around the burner door. Pull the burner forward and remove from the heat exchanger. Gently put to one side. 7: Once access has been gained to the combustion chamber and front section of the heat exchanger, inspect heat exchanger for any signs of overheating. 8: Using a NATURAL BRISTLE brush, and some MHG Heating boiler cleaning granules diluted in water, gently clean the heat exchanger ensuring all debris is removed and flushed through to the condensate drain. 9: Remove and clean out condensate syphon. Inspect condensate drain for any signs of leaks. If satisfied re assemble condensate syphon to boiler. 10: Inspect burner and burner door seals. If any signs of damage replace item. 11: Inspect ignition electrode and rectification probes. Replace on an annual basis or as required. Ensure gaskets are replaced along with probes to ensure a tight seal against burner door. 12: Inspect the fan and venturi assembly for any signs of damage or build-up of debris. Use compressed air or a brush to clean the venturi. Ensure the silicone tube between venturi and gas valve is clear and in good condition. If the fan blades have a build-up of debris a brush can be used to clean each blade in turn. Care must be taken to ensure the balance of the fan is not altered by the use of too much force. 13: Reinstall the burner, and burner door to heat exchanger ensuring all seals are intact. 14: Once the boiler is re assembled a gas tightness test must be carried out. 15: A Flue gas analysis must be completed on the completion of the tightness test. 55 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 14.0 Troubleshooting 56 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 57 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 15.0 Internal Wiring *Wiring loom and parameter adjustments required 58 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd 16.0 Spares Diagram Label Number 1 2 3 4 5 6 7 8 9 10 11 Item Description Combustion Fan Gas Valve Control Panel Heat Exchanger Ionization Electrode Ignition Electrode Ignition Transformer Limit Thermostat Pressure Sensor Flow Temperature Sensor Return Temperature Sensor Label Number 12 13 14 15 16 17 18 19 20 21 22 Item Description Automatic Air Vent Flue Gas Sensor Flue Gas Outlet Condensate Syphon Boiler Flow Connection Boiler Return Connection Gas Inlet Air Intake Venturi Condensate Syphon Level Switch Pressure Relief Valve 59 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417 © MHG Heating Ltd Notes 60 MHG Heating Ltd Unit 4 Epsom Downs Metro Centre, Waterfield, Tadworth, Surrey KT20 5LR Telephone 01737 358000 Fax 08456 448803 Email [email protected] Web www.mhgheating.co.uk 010417
