a Safety 2 The current ETCI Regulations for installing electrical equipment must also be observed. Installation and settings In the following cases, the boiler must be operated only with the front casing fitted and closed and with a completely mounted air/flue gas duct: – starting up – test purposes – continuous operation, Otherwise, under unfavourable operating conditions, injury, death or material damage may occur.
a a 2 Safety Attention shall be paid to (but not restricted to) the following: – Gas Safety (Installation and Use) regulations. – All Building Regulations 2000 for England and Wales, (as amended). – (Includes Approved Codes of Practice and Approved Documents for building regulations e.g. L1, L1A, L1B, L8.) – The Building Standards, Scotland, and any requirements determined by the local authorities within. – The current Version of I.S.
a Safety 2 > Please ensure that the boiler is room sealed or in a separate installation room if – the combustion air supply contains the aforementioned substances, – you install the boiler in hairdresser salons, painter's or joiner's workshops, cleaning businesses or similar. > Do not route the combustion air through an old oil furnace chimney, as this can also cause corrosion. means of completely isolating the boiler and its ancillary controllers.
a a 2 Safety Risk of damage if the heating water is treated with unsuitable frost or corrosion protection agents. Frost and corrosion protection agents can cause changes to seals, noise during heating mode and may lead to other consequential damage. > Do not use any unsuitable frost or corrosion protection agents. Mixing additives with the heating water can result in material damage.

Hydraulic installation 6 6.2 Connecting the hot and cold water 6.4 Low loss header A low loss header disconnects the boiler from the heating system. The system is no longer dependent on the remaining feed head of the boiler. In conjunction with the heating pump, the low loss header ensures that a sufficiently high minimum quantity of water is always circulating through the boiler. No electrical accessories are required in order to use a low loss header. 7 6 6.
6 Hydraulic installation > Connect the condensate discharge (1) of the boiler to a condensate discharge pipework (3) which has a minimum internal diameter of 19 mm (22 mm outside diameter for all external pipes) and is made from an acid-resistant material (e.g. plastic overflow pipe).
Flue gas installation 7 542 Air/flue gas duct 48 a Danger! Risk of death and risk of damage from use of non-approved air/flue gas ducts! Vaillant boilers are certified only with genuine Vaillant air/flue gas ducts. The use of other accessories can cause personal injury and material damage as well as operating faults. > Only use genuine Vaillant air/flue gas ducts. 901 7.1 Flue gas installation 1456 7 7.
7 Flue gas installation 7.2 Flue termination The following details refer to all flue systems. a.

You can use the DIA to display the current status of your boiler (Live monitor) and fault codes, to view and change parameters and to start test programs. Calling up the installer level b Caution. Risk of damage caused by incorrect handling. Incorrect settings at installer level can cause damage to the heating installation.
Commissioning 10 10 Commissioning At the time of commissioning, complete all relevant sections of the benchmark checklist found within the back pages of this document. Ensure that the filling and purging programs P.06 and P.00 have been allowed to run fully before the boiler is ignited for the first time.
10 Commissioning i 10.3 If the boiler is in error condition, you cannot start any test programs. You can detect an error condition by the fault symbol shown in the left bottom corner of the display (¬ fig. 10.1). You must first reset. If the heating installation extends over several storeys, higher filling pressures may be required to avoid air entering the heating installation. > Remove the front casing from the boiler (¬ section 4.7).
Commissioning 10 i If the water pressure in the heating system is too low, the display switches between fault message F.22 and the display of the current pressure when the boiler is switched on. > Purge the lowest radiator until water flows out of the purging valve without bubbles. > Purge all other radiators until the entire heating system has been filled with water. Close all purging valves. > Use the display to monitor the rising filling pressure in the heating installation.
10 Commissioning If the boiler version does not correspond to the local gas family: > Call Vaillant Service Solutions (0870 6060 777); Gas conversions must only be carried out by Vaillant Service Solutions. > You must not start up the boiler yourself. i 1 10.3 Filling the condensate trap > Remove the lower part (1) of the condensate trap by turning the bayonet fitting anti-clockwise. > Fill the lower section with water until about 10 mm below the upper edge.
Commissioning 10 – terminating test program P.01 as described in ¬ section 10.2. 1 – Allow the boiler to cool down by turning off water taps and allow pump overrun to operate for a minimum of two minutes. > Record the boiler maximum gas flow rate onto the Benchmark gas boiler commissioning checklist. 2 10.
10 Commissioning > Undo the sealing screw of the measuring nipple (1) (lefthand screw) at the gas valve using a screwdriver. > Connect a digital pressure gauge or U-tube manometer (2) to the measuring nipple (1). > Open the gas isolation valve of the boiler. > Start the boiler by activating the test program P.01 as described in ¬ section 13.3. > In addition, ensure that maximum heat can be dissipated into the heating system by turning up the room thermostat.
Commissioning 10 You can display the current operating condition of the boiler in the "Live monitor" on the boiler display (¬ section 13.2.1). 10.10.1 Checking the heating mode > Switch on the boiler. > Make sure that there is a heat requirement. > Activate the Live monitor (¬ section 13.2.1).

11 Adapting the boiler to the heating installation 11.1.1 Setting the heating partial load The heating partial load of the Vaillant ecoTEC pro boiler is factory-set to "auto". This means that the boiler independently determines the optimum heating output depending on the current heat demand of the system. A setting is normally no longer required. If you still want to set a fixed maximum heating partial load, you can set a value under diagnostic code "D.000", which equates to the boiler output in kW. 11.

Glossary 18 18 Glossary Air/flue gas duct Digital information and Analysis system (DIA) An air/flue gas duct is a line system with two separate flow channels. The flue gas is routed into separate chambers at the same time as the required combustion air is pumped to the boiler. The air/flue gas duct can be designed as a concentric or adjacent double flue gas pipe (the flue gas channel is sealed from the air channel).
