Installation requirements 7
Vaillant Vantage 120/150/200 15
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. If necessary provide
a frost protection thermostat.
– Access is available for user operation of the DHW tem-
perature control on the cylinder.
– Suitable clearances exist to allow installation, checking
and repressurising of the expansion vessel.
– The installation site chosen does not result in excessi-
ve ”dead leg” distances, particularly to the point of
most frequent use.
Note:
For larger systems incorporating long pipe runs
a secondary return connection is provided on
the top of the cylinder. A recirculation system
incorporating a suitable non ferrous pump may
be connected into this point.
– A suitable cold mains water supply pipe can be provi-
ded to the VANTAGE direct from the main water stop
valve of the building.
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.
Note:
Mains water pressures will reduce during periods
of peak demand. Ensure that measurements are
taken during these periods.
Once the available mains supply pressure and flowrate is
known the respective flowrate from the VANTAGE can
be obtained from fig. 7.
Example:
If the measured cold mains supply pressure is 2 bar
static and the cold mains flow rate available is 30 l/min,
the available flow rate of mixed water at 40 °C will be
25 l/min (from 15 l/min hot water from the VANTAGE
k 60 °C together with 10 l/min cold water @ 10°C).
The VANTAGE will operate satisfactorily with water supply pressures below 2 bar although flow rates will be
reduced. If the supply pressure is below 1 bar the
VANTAGE unvented storage cylinder should not be
installed. Contact Vaillant Ltd for details on alternative
hot water supply systems.
In order to minimise frictional losses minimum 3/4 inch
bore is recommended for new cold mains supply pipework into the dwelling although satisfactory performance can be achieved with 1/2 inch bore pipework.

Installation requirements 7
Vaillant Vantage 120/150/200 17
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.
Some designs of terminal fittings may allow excessive
flow rates resulting in user inconvenience and starvation
of other outlets. In these circumstances provide a valve
in the supply to that terminal fitting in order that the
flow rate can be regulated.
If the VANTAGE is being installed to existing pipework
with a 22 mm run to the bath terminal fittings and/or 15
mm to sinks/basins, an adjustable valve should be fitted
in the supply to each outlet: By adjustment of these valves, flow rates to fittings can be regulated to achieve
correct system balancing.
If the water capacity of the additional secondary pipework exceeds
20 litres (VANTAGE 120 or 200) or
10 litres (VANTAGE 150) an
additional expansion vessel may be required.
Pipe capacities for copper tube are:
15 mm 0.13 l/m
22 mm 0.38 l/m
28 mm 0.55 l/m
The cylinder may be drained completely for maintenance works via the drain valve (E, fig. 6) after first turning
off the water supply to the cylinder and opening the hot
draw off taps. Adequate access to the drain valve must
therefore be available.

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.
With the VANTAGE connected to a Vaillant boiler the
remaining pump head available, at a flow rate
corresponding to 20 °C temperature difference, is given
in table 3.
System Pipework should be sized such that the resistance of the heating circuit offering the greatest resistance to flow (the index circuit) does not exceed this
figure.
Vaillant Vantage 120/150/20018
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.
The discharge pipework must be installed using minimum 22 mm copper pipework from the 1" inch BSP
female connection on the tundish to a safe and visible
discharge point. There must be a vertical section of pipe
at least 300 mm long, below the tundish before any
bends or elbows in the pipework. Increase the diameter
of the pipework if the total resistance of the discharge
pipework exceeds the figures shown in table 4.
Example
22 mm discharge pipe having 4 elbows and a length of
7 m from the tundish to the discharge point:
Resistance for 4 elbows
at 0.8 m each = 3.2 m
Resistance of discharge pipe = 7.0 m
Total Resistance = 10.2 m
The total resistance of the discharge pipework is
greater than the maximum allowed for 22 mm
pipework (9 m). Therefore calculate the next largest
size.
28 mm discharge pipe with 4 elbows and 7 m length
from tundish to discharge point.
Resistance for 4 elbows
at 1.0 m each = 4.0 m
Resistance of discharge pipe = 7.0 m
Total Resistance = 11.0 m
The total resistance of the dischargepipework is less
than the maximumallowed for 28 mm pipework (18 m)
therefore the discharge pipework size is acceptable.
Minimum size Maximum total resistance Resistance created
of discharge allowed expressed as a by each elbow
pipework length of straight pipe or bend
from Tundish (i. e. no elbows or bends)
22 mm up to 9 m 0.8 m
28 mm up to 18 mm 1.0 m

Under fault conditions, the discharge warning pipe can
emit water at near boiling temperature. Ensure the
discharge pipe terminates at a safe position where there
is no risk of contact with hot water by persons in or
about the building.
A suitable position for the discharge point is ideally
below a fixed grating and above the water seal in a
trapped gully. Downward discharges at low level, i. e. up
to 100 mm above external surfaces such as car parks,
hard standings, grassed areas, etc. are acceptable providing that where children may play or otherwise come
into contact with discharges a wire cage or similar guard
is positioned to prevent contact, whilst maintaining visibility.
Do not fit any valves or taps to the discharge pipework.
Ensure the pipework has at least 1:200 fall
continuously from the tundish to the discharge point.
The discharge pipe from the pressure relief valve of the
Vaillant boiler may be teed-into the discharge pipework
from the VANTAGE downstream of the tundish.
7.5.1 High Level Termination
Providing that the point of termination is such that persons in or around the building will not be endangered
should discharge take place, the method of termination
shown in fig. 8a is satisfactory. Examples of points to
consider when deciding whether a location for the high
level discharge is suitable are:
– The possibility, taking into account wind effect, that
someone may be in the path of the water being
discharged and if so, whether the temperature of the
discharge water will have been sufficiently reduced to
not be dangerous. Thermal conductivity of the structure’s surface, climatic conditions and location and orientation of the discharge pipe may or may not have
an effect on reducing the temperature of the dischar-
ge water.
– The location of windows and similar openings.
– The likelihood of a pram being left beneath the point
of discharge.
– The ability of the structures surface to withstand near
boiling water.
– The possibility of ice formation if water is discharged
onto pedestrian walkways.

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
Note:
For VANTAGE 150 and 200 cylinders, remove
the blanking plug from the DHW thermostat
pocket located centrally at the top of the cylinder. Uncoil the sensing probe of the operating
thermostat and insert it FULLY into the pocket.
Secure the probe in position by fitting the retaining clip supplied (the VANTAGE 120 thermostat
probe is factory fitted).
8.1 Primary pipework
The 3 port valve is supplied prefitted to the VANTAGE
cylinder. The three ports of the valve are marked ”A”,
”B” and ”AB” (see fig. 9).
•
Connect the flow pipe from the Vaillant boiler to the
”AB” port of the three port valve.
•
Connect the radiator system flow pipe to the ”A” port
of the three port valve.
(The ”B” port of the 3 port valve is already connected to
the VANTAGE cylinder primary flow connection).
•
Install a return pipe from the cylinder return connec-
tion to the boiler return connection.
Note:
The primary return connection of the VANTAGE
cylinder must be joined into the return pipe from
the radiator circuit, and should be the last
connection before the boiler.
A balancing valve should be fitted between the
cylinder return connection and the return pipe
from the radiator circuit (see fig. 10). This valve
should be set to ensure correct primary flow

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.
Note:
The Expansion relief / non return valve has a
R 3/4 connection, and is supplied fitted with a
PTFE ring to ensure a watertight seal when
screwed into the pressure limiting valve (separate instructions are supplied with the control valves).
•
Provide a cold water mains supply to the VANTAGE.
To ensure optimum performance from the VANTAGE,
and particularly in installations where the balanced
pressure cold water outlet (2, fig. 11) is to be used, the
pipework provided from the building mains stop valve
to the VANTAGE cylinder should be minimum 22 mm
copper tube.
•
Install the assembled cold water control valves (fig. 11)
in the cold mains supply at a convenient position adjacent to the VANTAGE cylinder, ensuring adequate
space exists for service access.
Important
No valve shall be installed between the assembled cold water control valves and the cylinder.

•
Connect the expansion vessel to the installed water
controls by either:
i. Screwing the vessel directly into the control assem-
bly 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. The kit contains a wall
mounting bracket and a 1 metre flexible connection.
•
Connect the balanced pressure cold water supply (if
required) to the pressure limiting valve.
Note:
In areas where the mains water pressure is high
(4 bar or above) the cold water supply to a bath
or shower mixer valve can be taken from the
balanced pressure cold water outlet (2, fig. 11) of
the cold water controls. This will ensure that
both hot and cold supplies to the mixer valve
are at approximately the same pressure. The
cold water supply for all other terminal fittings
should be teed into the cold water supply pipework to the VANTAGE upstream of the cold
water controls.
•
Connect the DHW outlet pipework to the 22 mm
domestic hot water outlet on the VANTAGE (E, fig. 4).
Continue with 22 mm size pipe to the first tee fitting
after which 15 mm pipework should be adequate.
If the pipe runs are of excessive length or there are
several terminal fittings supplied, extend the length of
pipework in 22 mm. (See 7.3: Secondary System.)
8.3 Safety valve discharge pipework
•
Connect the temperature/pressure relief and expansi-
on relief valves to the tundish and install the discharge
pipework from the tundish in accordance with section
7.5: Discharge Pipework.

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.
Advise the user of the precautions necessary to prevent
damage to the system and to the building if the system
does not remain operative during frost conditions.
Advise the user that the immersion heater is provided
as a back up means of water heating and is not intended
for use at the same time that the Vaillant boiler is heating the cylinder.
Finally, advise the user that for continued efficient and
safe operation, the Vaillant boiler and VANTAGE cylinder
should be serviced at least once a year by a qualified
servicing company. It is important and strongly recommended that arrangements are made for a maintenance
agreement with a qualified servicing company to ensure
regular servicing of the Vaillant boiler and VANTAGE
cylinder.

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.
•
Turn off mains water supply and open nearest hot
water tap to depressurise the secondary water system.
Check the expansion vessel charge with a pressure
gauge at the test point. If the pressure is below
3.5 bar, top up with suitable air pressure pump.
•
Every 2 years check corrosion protection anode for
wear.
•
The anode has a life expectancy of approximately 6
years. It should be replaced if the diameter is less than
12 mm.
Servicing procedures for the Vaillant boiler are contained in the boiler installation and servicing instructions.
