1 Introduction These instructions describe the functioning, installation, use and primary maintenanceof Rinnaï central heating boilers for the United Kingdom and Ireland. Where necessary thedifferent regulations for each country are separately described. This appliance may only be installed by someone certified competent to do so.
Observe the following rules of safety: - All work on the boiler must take place in a dry environment. - Rinnai boilers must never be in operation without their housing, except in connection with maintenance or adjustments (see Chapter 13 and 14). - Never allow electrical or electronic components to come into contact with water. Carry out the following tasks in connection with maintenance, etc.
3 Scope of the supply The boiler is supplied ready for use. The supply kit is composed as follows: • • • • • • 4 Condensing Retrieves heat from the flue gases. Water condensates on the heat exchanger. Modulating Higher or lower burning according to the heat demand. Stainless Steel Super solid kind of steel which keeps its quality for life. It will not rust or erode in contrast to composition materials, like aluminium.
Mounting the boiler The room where the boiler will be placed must always be frost free. The boiler casing is splash water tight (IPX4D). It is NOT necessary to have a purpose provided air vent in the room or internal space in which the boiler is installed. Neither is it necessary to ventilate a cupboard or compartment in which the boiler is installed, due to the extremely low surface temperature of the boiler casing during operation.
5.
Connecting the boiler The boiler has the following connection pipes; - The central heating pipes. These can be connected to the installation by means of compression fittings / adapter fittings. Install the supplied service valves directly under the boiler; - The gas pipe. It is provided with a female thread into which the tail piece of the gas valve can be screwed; - The condensation drain pipe. It consists of a 22mm plastic pipe. The drain pipe can be connected to this by means of an open connection.
The maximum absorbed current consumption of the external circulation pump may be 230 W (1 Amp). The extra external pump must be selected according to the installation resistance and the required flow. As standard the boiler is provided with a water filter in the return pipe of the boiler. With this, possible contamination of the central heating water is prevented from ending up in the boiler. The boiler is also provided with an internal safety valve set at 3 bar.
6.2 Expansion vessel The central heating system must be provided with an expansion vessel. The expansion vessel which is used should be geared to the water content of the installation. The precharge pressure depends on the installation height above the mounted expansion vessel. See table 4. Fit the expansion vessel into the return pipe as close as possible to the boiler.
6.5 Condensation drain pipe Rinnai boilers produce condensate. This condensate must be drained otherwise the boiler will not function. The condensation drain pipe must be piped via a tundish because it is also the pressure relief valve drainage. If it is then piped into a drain or soil pipe it must be trapped after the tundish to prevent smells from entering the room. The drain connection should have a minimum diameter of 32mm. Connect the condensation drain pipe according to the actual regulations.
6.6 Flue gas exhaust system and air supply system The flue gas exhaust system and air supply system consists of: - Flue gas pipe; - Air supply pipe; - Roof or wall terminal. The flue gas exhaust system and air supply system must comply with: United Kingdom: The flue gas outlet and air supply installation must comply with the current regulation requirements. IGE UP 10 and BS 715. Ireland: - Irish standard is 813 section 9.10.
The appliance concentric connection diameter is 80/125mm, to which the flue gas outlet and air supply system can be fitted, with or without elbow pieces. The maximum permissible pipe length is set out in Table 5. We suggest you design a simple flue gas system and air supply system. For further information about the available components of the flue gas and air supply system we recommend you consult the Rinnai Flue system literature.
If the boiler is to be located under stairs, a smoke alarm meeting the requirements of I.S. 409 or equivalent must be fitted. The flue must be terminated in a place not likely to cause a nuisance. For horizontal sections, the outlet system should always be fitted on an incline (50 mm/ m) sloping down towards the appliance so that no condensation water is able to accumulate in the outlet system.
6.6.1 Dimensioning of the flue gas and air intake duct The flue diameter is determined by the total length of the run, including for the connection pipe, elbows fittings and terminal covers etc. Example: A 32kW with a concentric flue gas system ø80/125mm has according to the table a maximum flue straight length of 24m In the system that is going to be put in there are 2 x 87° bends, so the maximum flue gas length is 24 –(2 x -2.3) = 19.4 meters.
External hot water supply The separate Rinnai Infinity water heater has to be mounted according the instructions supplied with the mounting bracket together with the E boiler. Each appliance must be served via its own gas isolation valve and flue system.
8 Electrical connection The appliance complies with the CE Machinery Directive 89/392/EEC. The EC Low Voltage Directive 72/23/EEC and the EC EMC Directive 89/336/EEC. A 230V -50Hz mains electrical supply is required fused externally at 5A. The installation must continue to comply with: United Kingdom: - the national rules for electrical installations. Ireland: - the ECTI national rules for electrical installations The boiler electrical supply must be installed to the latest I.E.E. regulations.

8.1 Outside sensor The outside sensor is supplied seperately. Mounting Location The outside sensor should be mounted on the most exposed and coldest side of the building (north or north-east) at a height of min. 2 m above ground. When mounting the sensor mind external heat sources (heated chimneys, warm hot air from air shafts, installation on black surfaces, thermal bridges in the wall, etc.) which could falsify the measuring value.
9 Boiler controls The boiler is provided with a fully automatic microprocessor control, called CMS Control Management System. This system simplifies operation by undertaking all major control functions. Initially when power to the boiler is switched on it will remain on standby. There is no indication LED on, until one of the programme keys is pressed. The control panel display will show the relevant state. When the installation is empty the display will show FILL.
9.1 Explanation of the function keys When the pump is switched on continuously it can lead to undesired heating up of the central heating system during the summer. - Central Heating program key. Switching the Central Heating on or off (LED on/off); - DHW key: Not applicable. - PC program key. adjusts the pump to continuous water circulation in the central heating system (LED on), or according to the pump overrun times on the relevant programs (LED off); • Mode-key.
10 Filling and venting the boiler and installation The central heating installation needs to be filled with potable water. For filling or topping up the installation use the filling loop according to the following procedure: 1 Switch on the power supply; 2 The diplay will show FILL; 3 All functions off (heating, DHW and pump); 4 Push briefly the 'STEP'-button: P x.x = water pressure in bar; 5 Open the filling loop (Indication on display increases); 6 Fill up slowly to 1.5 to 1.
11 Commissioning the boiler Before the boiler is fired, ensure that the boiler and the system are well vented and free of air. Purge the gas line between the gas meter and the boiler and carry out a gas soundness test as specified in the current Gas Safety, Installation & Use Regulations. The boiler does not require adjustment of the burner pressure and air quantity because it is self adjusting and is factory set at the correct value. 11.
11.2 Adjustments When the boiler is installed it is in principal ready for use. All adjustments of the boiler control are already pre-programmed for a heating system with radiators/convectors with a flow temperature of 85°C. The adjustments are described in the Parameter chapter on page 26. In certain cases adjustment have to be altered in case of : - Lower flow temperature Read through the Parameter chapter to adjust the boiler to its installation. Contact Rinnai Heating in case of doubt.

12 Isolating the boiler In some situations it may be that the entire boiler must be switched off. By switching or ), off the three keys with the lamps for central heating and pump program ( the boiler is switched off. Leave the 230V mains supply switched on so as the circulation pump is activated once every 24 hours in order to prevent jamming. In the event of frost danger it is advisable to drain the boiler and/or the installation.
13.1 Checking for contamination In order to be able to check the boiler for contamination in the following running years it is advisable to measure the maximum air displacement in the boiler when putting the boiler into operation. This value can be different with each type of boiler. Check point contamination figure 9 - Press the Central Heating and DHW buttons once to ensure that the boiler is OFF and not firing. - Press the MODE-key for 5 seconds.
13.2 Checking the CO2 The CO2 percentage is factory-set. This has to be checked at commissioning, maintenance and faults. This can be checked by means of the following procedure: - Remove the black cover of the gas valve by unscrewing the sealed screw. checkpoint CO2 - Put the boiler into operation and take care that it can deliver its heat; - Press the MODE-key for 5 seconds.
14 Maintenance Maintenance or changes to the boiler may only be carried out by an authorised technician. 14.1 The frequency of maintenance We advise that an inspection is carried out every year with an overhaul every three years. When doing this the circumstances of the boiler’s location must be taken into account. From this one can determine whether to deviate from this advice. Please contact Rinnai for further guidance on the frequency and service requirements.
Ignition electrode The replacement of the electrode is only necessary when the electrode is worn off. This can be checked by measuring the ionisation current. The minimum ionisation current has to be higher then 4µA on full load. If the viewing glass is damaged the complete electrode must be replaced.
