Functional description 6 6 Functional description 6.1 D.H.W. Temperature Control The VANTAGE is supplied fitted with a user adjustable domestic hot water (DHW) thermostat and also a 3 port mid position diverter valve. 6.2 C.H. Control Central heating is controlled by the fitted 3 port mid position diverter valve in conjunction with suitable external controls, such as a programmer, room thermostat or thermostatic radiator valves.
6 Functional description 6.4 Secondary System The VANTAGE is provided with all necessary safety and control devices for unvented DHW operation. These are as follows: A A prefitted temperature and pressure relief valve (90 °C, 7 bar) (An additional overheat thermostat is contained within the Vaillant boiler). B Expansion relief valve (6.0 bar) incorporating a non return valve. C Pressure limiting valve (3.5 bar) incorporating a line strainer.
Installation requirements 7 7 Installation requirements 7.1 Siting Locate the VANTAGE in the building in the most convenient position ensuring that: – The discharge pipe from the tundish can be installed with a minimum fall of 1:200 and can be terminated in a safe and visible position (see section 7.5 Discharge pipework). – The base chosen for the unit is level and capable of supporting the weight of the cylinder when full (see section 2: Technical Data). – The installation site is frost-free.
7 Installation requirements 7.2 Mains Water Pressure The DHW performance of an unvented cylinder installation will correspond to the available mains water supply pressure and flow rate. To achieve optimum performance from the VANTAGE a suitable cold mains water supply must be available, i. e. the measured static pressure from the incoming mains water supply should be at least 2.0 bar. A corresponding flow rate at least 20-25 l/min should be available.
Installation requirements 7 7.3 Secondary System To achieve optimum distribution of the water supply it is important that the water system pipework and terminal fittings are correctly sized and balanced. The teed-off supply to the bath outlet should be in 15 mm pipework. The tee-offs to sinks and basins should be in 10 mm pipework. Terminal fittings should be suitable for mains pressure operation and taps should be of the aerated type to prevent splashing. Flow rates from VANTAGE, hot 60 °C.
7 Installation requirements 7.4 Pipework – Primary Circuit The primary circuit pipework between the Vaillant boiler and the VANTAGE should be installed using copper tube of minimum size 22 mm. If the distance between the boiler and the cylinder is excessive, a larger pipe diameter may be necessary. It is not necessary to install a circulating pump in this pipework because all Vaillant wall mounted boilers contain a built-in circulating pump.
Installation requirements 7 7.5 Discharge Pipework The outlet connections of both the temperature and pressure relief valve and expansion relief valve should be connected in 15 mm copper tube to the tundish supplied. The tundish should be installed vertically, as close to the VANTAGE as possible and within 500 mm of the temperature and pressure relief and expansion relief valve outlets. It must be positioned away from any electrical components and installed in the same space as the VANTAGE cylinder.
7 Installation requirements Typical discharge pipe arrangement metal discharge pipe from temperature relief valve to tundish safety device (e.g. temperature relief valve) 500 mm maximum tundish Discharge below fixed grating 300 mm minimum metal discharge pipe from tundish with continuous fall. See 7.5 Table 4 and worked example fixed grating VIH 365/1 trapped gully Under fault conditions, the discharge warning pipe can emit water at near boiling temperature.
Installation procedure 8 8 Installation procedure • Unpack the VANTAGE cylinder and check the contents (detailed in section 1: notes to installers). • Position the VANTAGE in accordance with section 7.1: Siting W M H ´A´ Port heating flow ´AB´ Port boiler flow Fig. 9 VIH 366/1 ´B´ Port to cylinder Note: For VANTAGE 150 and 200 cylinders, remove the blanking plug from the DHW thermostat pocket located centrally at the top of the cylinder.
8 Installation procedure 8.2 Secondary system Pipework • Connect the two cold water control valves together as shown in fig 11., ensuring that the orientation of the valves, when installed in the cold mains supply, allows the 15 mm outlet of the expansion relief valve to be connected to the tundish.
Installation procedure 8 • Connect the expansion vessel to the installed water controls by either: i. Screwing the vessel directly into the control assembly at the purpose provided connection (3, fig. 11) or, ii. Connecting the vessel to the control assembly via copper pipe or a suitable approved flexible connection hose, ensuring that the vessel is adequately supported. Note: An optional ”Remote Expansion Vessel Mounting Kit” (Art no. 2378083) is available for use with VANTAGE cylinders.

Installation procedure 8 8.4 Electrical connections and controls Immersion heater electrical connections 8.4.1 Immersion Heater Warning: The immersion heater must be earthed. Install a separate electrical supply to the immersion heater in accordance with the current IEE wiring regulations (BS 7671). The immersion heater must be wired in 2.5 mm2 heat-resisting cable from a double pole isolating switch. The circuit must be protected by a 13 amp fuse.

9 Commissioning 9 Commissioning 9.1 Filling Secondary D.H.W. Circuit Note: Do not manually open the temperature and pressure relief valve or expansion relief valve for venting purposes (any foreign matter in the pipework may cause damage to the valve seats). • Ensure that the cylinder drain valve (E, fig. 6) is clo• • • sed. Open all the hot and cold water taps or other terminal fittings.
Commissioning 9 9.2 Filling the Primary Circuit Note: Do not use boiler pressure relief valve for venting purposes. • The complete primary C.H. system must be flushed • • • • • out with both cold and hot water. Fill and vent the central heating system as detailed in the boiler installation instructions. To assist with this operation set the manual override lever on the 3 port diverter valve (fig. 9) to the MANUAL position, and lock in this position by pushing the lever into the valve head.
9 Commissioning 9.4 User’s Instructions Hand the instructions for use to the user for retention and instruct in the safe operation of the boiler and cylinder. Advise the user of the operation of the cylinder thermostat, and that normally a setting of 5-6, which gives a stored water temperature of approximately 60 °C is adequate. Note: In hard water areas the DHW temperature setting should not exceed this setting to avoid possible scale build-up.
Maintenance 10 10 Maintenance The following maintenance work has to be carried out annually by the competent installer or Vaillant Service Solutions. • Inspection of pressure/temperature relief valve and • • • • expansion relief valve. Manually operate each valve by twisting the operating cap, and check if water flows unobstructed via the tundish to the discharge point. Ensure that both valves re-seat satisfactorily. Check pressure of expansion vessel.
