Page 4: Introduction
The current, Electricity at Work Regulation must be complied with and also be in accordance with the relevant and current editions of the British Standards. The Rinnai E boiler is a certified appliance and must not be modified or installed in any way contrary to this Installation Manual. - Page 5 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).

Page 6: Scope Of The Supply
Outside sensor (separate delivery) Description of the boiler Room sealed boiler The Rinnai E boiler is a room sealed, condensing, modulating central heating boiler. The boiler retrieves its combustion air from the The boiler is provided with a compact stainless steel heat exchanger with smooth outside then discharges tubes. -
Page 7: Mounting The Boiler
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. -

T 20°C installation type resistance l/min mbar E32S UP 20-60 20.7 1244 Installation resistance table 3 If the installation resistance is higher than the stated value the load will be adjusted until an acceptable temperature difference between flow and return water has been obtained. - Page 10 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.

Make sure that the gas pipe work does not contain dirt, particularly with new pipes. When the boiler has to be converted from natural gas to LPG, Rinnai provides special kits for this purpose. Special instructions are supplied with the kit. -
Page 12: Condensation Drain Pipe
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. -
Page 13: Flue Gas Exhaust System And Air Supply System
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. - Page 14 Rinnai Flue system literature. The Rinnai flue gas system is meant and designed solely for the use on Rinnai central heating boilers adjusted to Nat gas or LPG. The maximum flue gas temperatures are below 70°C (full load 80/60°C)
- Page 15 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.

Page 17: External Hot Water Supply
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. -

Domestic Hot Water flow switch. This switch, when installed in the cold water flow to the Rinnai water heater and wired to break the DHW flow switch electrical connection, will prevent the boiler from operating when the water heater is operating. -
Page 20: Outside Sensor
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. -
Page 21: Boiler Controls
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. -

Page 24: Commissioning The Boiler
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. -
Page 25: Adjustments
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. Please follow next procedure to alter adjustments: Altering adjustments Press the Mode-key for 5 secondss. - Page 26 Parameter chapter PARA Factory Description Range 85°C maximum flow temperature CH 20 - 90°C type of CH installation: radiators; air heating; convectors: T max. flow 85°C; K factor heating line 2.3; gradient 5°C/min; gear differential 6°C radiators with large surface areas or underfloor heating as additional heating: T max.

Isolating the boiler In some situations it may be that the entire boiler must be switched off. By switching 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. -
Page 29: Checking For Contamination
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. In order to be able to measure this value follow the next procedure: Press the Central Heating and DHW buttons once to ensure that the boiler is OFF and not firing. -
Page 30: Checking The Co 2
13.2 Checking the CO The CO 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. Put the boiler into operation and take care that it can deliver its heat;... -
Page 31: 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. 14.2... -

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. Replacement goes as follows: remove the electrical connections of the electrode;... -
