2 ABOUT THE ATLANTIC R-SERIES BOILER The ATLANTIC R-Series year-round maximum condensing boiler has two distinct heat exchangers, the first of developed quality steel design and the second of high grade plastic design. The flue gases leave the first heat exchanger at temperatures below 90 C, and are then extracted from the second condensing heat exchanger at temperatures always below 50 C. The introduction of combustion air through the condensing exchanger lowers the flue gas temperature below dew-point, hence there is no need for return water temperature to be low. BURNER MAIN HEAT EXCHANGER HEATING FLOW & RETURN FRESH AIR The boiler will condense to it's maximum efficiency even at 82 C flow & 71 C return. For combustion air, at inlet temperatures below 30 C, efficiencies always exceed 92%. These conditions apply throughout the year in the UK. CONDENSING EXCHANGER FLUE GASES TREATED CONDENSATE The lower part of the condensing exchanger has a condensate neutralising section built in, eliminating the need for separate equipment in the future. The ATLANTIC R Series boiler pipework requirements are as straight forward as a conventional boiler or a high efficiency boiler. No special circuits are required to create condensing. Cross section of main heat exchanger Front view of main heat exchanger (purple) and of condensing exchanger frame (yellow) IN-BUILT FEATURES Constant temperature requirements are achieved with boiler controller, shunt pump, 4-port valve and flow sensor. Minimum flow and minimum temperature requirements are achieved with boiler controller, pump, 4-port valve and sensor. Variable temperature requirements are achieved with boiler controller, shunt pump, 4-port valve, outside sensor and flow sensor. All the above systems can be provided by the boiler system. Alternatively, the ATLANTIC R Series boiler(s) can be enabled by a BMS system and also can provide alarm signals to a BMS system. The boiler(s) will continue their own in-house operational control ensuring correct combustion and hydraulic function. As a modulating burner option, the boiler controller system can be modified on a 0-5 volt and 0-10 volt band to give variable heat output.

The burner fires horizontally through the combustion chamber and makes a series of passes through a horizontal heat exchanger. The steel boiler is externally covered with an 80mm layer of rock wool thermal insulation. Access to the heat exchanger is through a panel at the front of the boiler secured by four bolts. The condensing exchanger is made of polypropylene and contains a series of smooth polypropylene heat exchanger tubes. The bottom of the condensing exchanger has a section containing limestone granules to neutralise the condensate. The boiler has a pre-wired control panel incorporating an isolator switch with indicator lamps, modulating, high/low or on/off burner control, water flow sensor with indicator lamps, a safety limit thermostat, hours run indicator, flue gas thermometer and a weather-controlled programme. The boiler assembly includes a 4 way valve, a shunt pump, both pre-wired and operated by the control panel, and a shunt pipe arrangement with connections for a restricted constant temperature circuit. The pressurised B100 or gas burner has; aluminium body, motorised fan air supply, oil or gas valve with controlled rate of opening, ignition transformer, air/b100 or air/gas mixing, combustion head, differential pressure switch, control box with ionisation flame protection, balanced flue pressure switch controls. Burners are available with pre-mix, modulating, high/low and on/off operation depending on fuel type and model size. The flue gas fan(s) in each boiler assembly contain - aerodynamic polypropylene housing, vibration free mountings, minimum pressure loss inlet & outlet, totally enclosed synchronous motor, maintenance free, dust & water proof bearings, infinitely adjustable fan motor speed regulator. The number of fans depends on the boiler model. From the model R22-15 to the model R22-90 the fan is mounted within the boiler casing. From model R upwards, the multi-fan assembly is mounted to the rear of the boiler.

6 PIPEWORK ARRANGEMENTS Each boiler has its own header with in-built 4-port valve and shunt pump. This guarantees minimum water flow and temperature control. Single and group boilers can use a balancing & sedimentation vessel or a low velocity header as a neutral heat outlet. Any number of circuits, in order of priority, can then be served adequately from the boiler(s) TYPICAL ONE BOILER ARRANGEMENT One R22 boiler serves domestic hot water (priority) and weather compensated radiators. The fast-response indirect cylinder always needs to receive primary hot water within 1 or 2 minutes of demand so it receives priority from the balancing vessel or header. The radiators have a response time of about 20 minutes so they take primary heat as a second function. Consequently the indirect cylinder is served first from the balancing vessel. BALANCING VESSEL Domestic Hot Water Priority Weather compensated space heating ACFE Auto top up unit and fast fill bypass kit DHW MULTIPLE BOILER ARRANGEMENT This might be a typical medical centre situation where duty and standby boiler plant serves sanitary hot water, air conditioning and underfloor space heating. The ultra-fast response plate heat exchangers need primary heating within a few seconds, the air conditioning (in mid-winter) needs primary heating within a few minutes, whereas the underfloor space heating has a much longer response time. The plate heat exchangers are served first from the balancing vessel, the air conditioning second and the under-floor heating last.

7 CONDENSING FLUE ARRANGEMENT The ATLANTIC R Series boilers can have either conventional or balanced flues for diesel oil, kerosene, natural gas or LPG. The boiler flue requirements are economic often cutting the costs of material and labour when compared to other boilers. As the flue gas exit temperature is always low, the volume of gases is always greatly reduced throughout the year.

The flues are graded to the boiler(s) to allow the condensate to drain to the tank in the base of each boiler. The condensate is then treated using limestone marbles before flowing out to a normal drain. TECHNAFLON condensing flues are precision-made from polyvinylidene fluoride (PVDF) which is extremely corrosion-resistant, hard wearing and not effected by ultra-violet radiation. The flues are installed without insulation. The flue gases cool rapidly, releasing the heat to the building and increasing the plant efficiency.

8 BALANCING AND SEDIMENTATION VESSEL The balancing vessel is located close to the boilers, with its feet placed on a base to allow the boiler flows and returns to normally vent to the vessel. One full size cold feed pipe should be taken to the connection P on the vessel and fitted with a normally open ball valve, allowing unrestricted heating system expansion and contraction to take place along the pipe. The different flow pipes of separate heating circuits should be connected progressively down the header from the top flow 'A'. The returns should be connected similarly upwards from the bottom return 'I'. DHW priority flow and return circuits should be taken from and to the high level W tappings. When connections are complete and the system is ready for filling. Firstly everything should be isolated from the vessel. This includes the boilers (with their shunt pumps) connected to L (flow) and M (return) and the heating circuits - 'A' and 'I'. - which should be isolated from the vessel. The vessel air vent V and drain/sludge valve D should be closed. The different heating circuits should then be filled separately. As the circuits are progressively filled, they should be regularly sludged through the bottom of the vessel by opening the circuit valves and the drain and sludge valve until the BSV AND SV STANDARD DIMENSIONS Capacity Diameter 116kW 100mm 348 kw 150mm 696 kw 200mm 1740 kw 300mm 2900 kw 500mm water clears. This should be repeated for all the circuits. After filling all the circuits, the circuit pumps should be set running to check for further sedimentation arriving in the vessel. When this is clear, the boiler valves may be slowly opened and then the shunt pumps set running.
