Vitodens 200-W
1.1 Product description
A Inox-Radial heat exchanger made from stainless steel - for high
operational reliability and a long service life. Large output in the
smallest of spaces
B Modulating MatriX cylinder burner for extremely clean combustion
and quiet operation
C Variable speed combustion fan for quiet and economical operation
D Gas and water connections
E Digital boiler control unit
Vitodens 200-W wall mounted condensing boilers up to 105 kW are
especially suitable for installation in apartment buildings and commercial or public buildings. For these, the Vitodens 200-W offers an affordable, space-saving solution – either as a single unit up to 105 kW or
as a cascade with up to four boilers and an output up to 420 kW.
The Inox-Radial heat exchanger made from stainless steel offers high
output in the tightest of spaces. This enables particularly efficient operation with standard efficiency up to 98 % (Hs)/109 % (Hi).
The Vitotronic 300-K cascade control unit regulates up to four Vitodens
200-W as a single heating centre. In this way, the boiler output is automatically matched to the heat demand. This means subject to the prevailing demand, either one boiler modulates or all four boilers operate
concurrently.
For the construction of cascade systems, we offer perfectly matching
system design, e.g. control units with up to four appliances, fully insulated hydraulic cascades or flue gas headers.
Recommended applications
High output from a compact, user-friendly wall mounted boiler, suitable
for the following applications:
■ Systems with few, large-demand consumers, e.g. fan heaters in
supermarkets/markets, workshops and industrial premises, nurseries, garages and DHW heating systems
■ Systems with several heating circuits for underfloor and/or static
radiators in multi-occupancy dwellings, central heating plants for terraced houses, office buildings and administration premises - particularly suitable for attic heating centres
■ Heating of public buildings, such as sports and multi-purpose halls,
schools, kindergartens
■ Suitable for installation in basement boiler rooms, on single floors or
in the attic.
Benefits at a glance
■ Wall mounted gas condensing boiler as central heating boiler, 17 to
105 kW
■ As multi-boiler system with cascade control and up to 4 Vitodens
200-W (up to 420 kW)
■ Standard seasonal efficiency [to DIN]: up to 98 % (Hs)/109 % (Hi)
■ Durable and efficient through the Inox-Radial heat exchanger

Heating circuit pumps regulated by differential pressure
According to the [German] Energy Savings Order (EnEV), circulation
pumps in central heating systems must be sized in accordance with
current technical rules. Circulation pumps in central heating systems
with rated output higher than 25 kW should be equipped and designed
in such a way that the power consumption will be automatically
matched to the operational (capacity) requirements in at least 3 stages,
if no safety concerns relating to the boiler make demands to the contrary.
In addition to the EnEV regulations, the use of regulated pumps is also
recommended for smaller capacities.
Design information
The use of differential pressure regulated heating circuit pumps
requires heating circuits with variable flow rate, e.g. single line and
twin-line systems with thermostatic valves, underfloor heating with
thermostatic or zone valves.

ÖVE und der landesrechtlichen Bestimmungen einzuhalten.
Vitodens 200-W from 60 kW and multi-boiler systems
Install boilers from 50 kW in accordance with the Combustion Order
(FeuVo) [Germany] [or local regulations] in a separate installation
room. Fit the main isolator outside the installation room.
Combustion air apertures
Gas equipment with a total rated output in excess of 50 kW must be
provided with combustion air apertures leading to the outside. The
cross-section should be at least 150 cm2 and should be 2 cm2 larger
for each kW above 50 kW rated output. This cross-section may not be
split over more than 2 apertures (observe FeuVo and TRGI 2008 point
5.5.4 [or local regulations]).
Example:
Vitodens 200-W, 3 × 60 kW
Total rated output 180 kW
150 cm2 + 130 × 2 cm2 = 410 cm2 or 2 × 205 cm2.
The combustion air apertures should be at least 410 cm2 or 2 ×
205 cm2.

< 7 m above ground level)
■ Bathrooms and toilets without outside windows with duct ventilation
■ Rooms where explosive or flammable materials are stored
■ Rooms ventilated mechanically or via individual duct systems to DIN
18117-1.
Observe all local fire regulations.
Connection on the flue gas side
(for further details, see the technical guide "Flue gas systems for the
Vitodens")
The connecting piece to the chimney should be as short as possible.
Therefore position the Vitodens as closely to the chimney as possible.
No special protective measures or clearances towards combustible
objects, e.g. furniture, cartons or similar, need to be taken/observed.
The surface temperatures of the Vitodens and the flue system never
exceeds 85 ºC anywhere.
Extractors
When installing devices with extraction to the outside (cooker hoods,
extractors, etc.), ensure that air extraction will not create negative
pressure inside the installation room. A return flow of flue gases could
result, if the ventilation system and the Vitodens were to operate simultaneously. In such cases, install an interlocking circuit.
For this, the internal extension H2 (accessories) can be used. This
switches the extractors OFF when the burner is started.
Installation conditions for balanced flue operation (appliance type C)
5822 432 GB
The Vitodens can be installed as appliance type C13x, C33x, C43x, C53x
or C63x to TRGl 2008, for balanced flue operation independent of the
size and ventilation of the installation room.
VITODENS 200-W
It may, for example, be installed in recreation rooms, in other living
space, in ancillary rooms without ventilation, in cupboards (open at the
top) and recesses without maintaining minimum clearances to combustible parts as well as in attic rooms (pitched attics and ancillary
rooms) where the balanced flue pipe can be directly routed through
the roof. Since the flue pipe connecting piece for balanced flue operation is surrounded by combustion air (coaxial pipe), no clearances
towards combustible parts need to be maintained (for further details,
see the technical guide "Flue gas systems for the Vitodens").
The installation location must be safe from the risk of frost.
Provide a condensate drain and a blow-off line for the safety valve in
the installation room.

Design information (cont.)
Electrical interlocks for extractors (extractor hoods, etc.) are not
required with balanced flue operation.
Vitodens 200-W from 60 kW
Install boilers from 50 kW in a separate room in accordance with the
Combustion Order (FeuVo) [Germany] [or local regulations]. Fit the
main isolator outside the installation room.
Appropriate ventilation air and extract air apertures are required in
accordance with TRGI (see the technical guide on flue gas systems
for the Vitodens).
Installation in a garage
Tests carried out by the Gaswärme-Institut e.V., Essen, have confirmed that the Vitodens is suitable for installation in garages.
When installing this boiler in garages, maintain a clearance between
the floor and the burner of at least 500 mm. Protect the boiler on site
with a bracket or deflector against mechanical damage.
Operation of the Vitodens in wet areas
The Vitodens is approved for installation in wet areas (protection
IP X4 D, splash-proof)
When installing the Vitodens in wet areas, observe the safety zones
and minimum wall clearances according to VDE 0100 [or local regulations]. The Vitodens 200-W may be installed in safety zone 1.

Protect the power cable with a fuse with a max. rating of 16 A.
We recommend installing an AC/DC-sensitive RCD (RCD class B) for
DC (fault) currents that can occur with energy-efficient equipment.
Make the power supply (230 V~, 50 Hz) via a permanent connection.
Connect the supply cables and accessories at the terminals inside the
boiler.
Allow cables/leads in the shaded area to protrude at least 800 mm from
the wall (see diagram):
Design information (cont.)
Additional requirements when installing boilers with LPG operation in rooms below ground level
According to TRF 1996 Vol. 2 – valid as of 1 September 1997 – an
external safety solenoid valve is no longer required when installing the
Vitodens below ground level.
However, the high safety standard derived from the use of an external
safety solenoid valve has proved to be valuable. We therefore recommend the installation of an external safety solenoid valve when installing the boiler in rooms below ground level. This requires the internal
extension H1.
Gas connection
Gas installations must only be carried out by an approved gas fitter
[CORGI] who has been authorised by the relevant gas supply utility.
Connect and size the mains gas according to TRGI 2008 or TRF 1996
[or local regulations].
a Connect the mains gas according to ÖVGW-TR Gas (G1) and
the regionally applicable Building Regulations.
Max. test pressure 150 mbar.
We recommend the installation of a gas filter compliant with DIN 3386
into the gas supply line.
Thermally activated safety shut-off valve
According to paragraph 4, sect. 5 of the FeuVo '96 [Germany], thermally activated shut-off equipment, that isolates the gas supply if
external temperatures exceed 100 ºC, must be installed in gas combustion equipment or in gas supply lines. These valves must isolate
the gas supply for at least 30 minutes up to a temperature of 650 ºC.
This should prevent the formation of explosive gas mixtures in the
event of a fire.
The gas taps supplied with the Vitodens are equipped with integral
thermally activated safety shut-off valves.

Condensate drain and neutralisation
5822 432 GB
Drain the condensate created during the heating operation in the condensing boiler and in the flue pipe in accordance with appropriate regulations. During gas combustion, the condensate will have a pH
between 4 and 5.
The Code of Practice ATV-DVWK-A 251 "Condensate from condensing boilers", that is generally based on the local waste water regulations [in Germany], determines conditions for draining condensate
from condensing boilers into the public sewer system.
The consistency of condensate drained from Vitodens condensing
boilers meets the requirements specified in the Code of Practice ATVDVWK-A 251.
The condensate drain to the sewer connection must be able to be
inspected.
It must be installed with a continuous gradient and must contain a
stench trap. Also provide a suitable facility for extracting samples.
Condensate drains must only be made from corrosion-resistant materials (e.g. reinforced hoses).
Never use any galvanised materials or those containing copper
for pipes, connectors, etc.
A siphon is installed in the condensate drain to prevent flue gases
escaping.
Local waste water regulations and/or specific technical circumstances
may specify designs that vary from those described in the above
Codes of Practice.
It is advisable to contact your local authority responsible for waste
water management prior to installation, to find out about local regulations.
Condensate from gas combustion equipment up to 200 kW combustion output
Up to a rated output of 200 kW, the condensate from a gas condensing
boiler can generally be introduced into the public sewer system without
prior neutralisation.
Also ensure that your domestic dewatering system is made from materials that are resistant to acidic condensate.
According to the Code of Practice ATV DVWK A 251, these materials
include:
■ Clay pipes
■ Hard PVC pipes
■ PVC pipes
■ PE HD pipes
■ PP pipes
■ ABS/ASA pipes
■ Stainless steel pipes
■ Borosilicate pipes

sewer side, and must provide a suitable facility for extracting samples.
Install a condensate lifting pump if the Vitodens has been installed
below the waste water antiflooding level.
Condensate lift pumps are available as accessories (see the Vitoset
pricelist).
Since the consumption of neutralisation granulate depends on the
operating mode of the system, determine the required top-up amount
during the first year of operation by regular checks. It is feasible that
one fill may last longer than 12 months.

4.3 Hydraulic connection
General
System design
Viessmann condensing boilers can generally be installed in any pumped hot water heating system (sealed system).
Connection sets with integral circulation pump are available as accessories.
Minimum system pressure 1.0 bar.
The boiler water temperature is limited to 82 ºC.
To minimise distribution losses, we recommend that you size the heat
distribution system to a max. flow temperature of 70 ºC.
Chemical anti-corrosion agents
Corrosion is generally avoided in correctly installed and operated
sealed heating systems.
Never use chemical anti-corrosion agents.
Some manufacturers of plastic pipes recommend the use of chemical
additives. In such cases, only use anti-corrosion agents offered by the
heating trade that have been approved for boilers with DHW heating
via single-walled heat exchangers (instantaneous water heater or
DHW cylinder).
For this, observe the VDI guideline 2035 [or local regulations].
Heating circuits
For heating systems with plastic pipes, we recommend the use of
impermeable pipes to prevent the diffusion of oxygen through the pipe
walls.
Provide system separation in heating systems with plastic pipes to DIN
4726 that are permeable to oxygen. We supply a separate heat
exchanger for this.
Install a sludge separator in underfloor heating systems and systems
with a large water content; see the Viessmann Vitoset pricelist.
Connect underfloor heating systems with very large water content
(>15 l/kW), even with condensing boilers, to heating circuits via a 3way mixer; see technical guide "Control of underfloor heating systems" or the relevant sample applications.
Install a temperature limiter into the flow of the underfloor heating circuit to limit the maximum temperature. Observe the requirements of
DIN 18560-2 [or local regulations].
Plastic pipework for radiators
We also recommend the installation of a temperature limiter to restrict
the maximum temperature of plastic pipes in heating circuits with radiators.
Safety valve
A safety valve in accordance with TRD 721 is part of the heating circuit
connection set (accessory) (opening pressure 4 bar).
Route the blow-off line in accordance with EN 12828 into a drain outlet
(drain outlet kit available as an accessory). The drain outlet incorporates a siphon as a stench trap.
Low water indicator
According to EN 12828, a low water level indicator can be omitted for
boilers up to 300 kW, as long as heating can be reliably prevented
when the water level is too low.
Viessmann Vitodens boilers are equipped with a low water indicator
(boil-dry protection). Tests have verified that the burner will be automatically switched OFF in the event of water shortage due to a leak in
the heating system and simultaneous burner operation, before the
boiler or the flue system reach unacceptably high temperatures.
Attic heating centre
The installation of a low water indicator specified as compulsory by
DVGW is not required when installing the Vitodens in an attic.
The Vitodens condensing boilers are protected against low water levels in accordance with EN 12828.
Water quality/Frost protection
Unsuitable fill and top-up water increases the level of deposits and
corrosion and may lead to boiler damage.
Regarding the quality and volume of heating water, incl. fill and top-up
water, observe VDI 2035.
■ Thoroughly flush the entire heating system prior to filling it with water.
■ Only use fill water of potable quality.
■ Fill water with a water hardness in excess of the following values
must be softened, e.g. with the small softening system for heating
water (see the Viessmann Vitoset pricelist):
– Vitodens up to 45 kW: 16.8 °dH (3.0 mol/m3)
– Vitodens from 60 kW and multi-boiler systems up to 200 kW:
11.2 °dH (2.0 mol/m3)
– Multi-boiler systems above 200 kW: 8.4 °dH (1.5 mol/m3)
■ An antifreeze additive suitable for heating systems can be added to
the fill water. The antifreeze manufacturer must verify its suitability,
since otherwise damage to gaskets and diaphragms can occur as
well as noise during heating operation. Viessmann accepts no liability for damage or consequential damage as a result.
■ For commissioning or systems with a volume that is in excess of
20 litres/kW, observe VDI 2035.
Installation examples
For installation examples for the Vitodens 200-W, see "System examples".
Expansion vessels
In accordance with EN 12828, water heating systems must be equipped with an expansion vessel.
The size of the expansion vessel is subject to the heating system
specification and should be checked in each case.

Design information (cont.)
■ Generally install a low loss header with the Vitodens 200-W in multiboiler systems.
■ When balancing the low loss header, adjust the flow rate on the
equipment side approx. 10 to 30 % lower than the flow rate on the
system side (reducing the return temperature).
■ The low loss header should be sized for the max. volume flow that
may occur in the overall system.
The low loss header separates the heat source (boiler circuit) from the
downstream heating circuits.
Install a low loss header if the maximum flow rate of an individual
design is greater than the values shown in the table below.

Boiler circuit
The circulation pump in the Vitodens must be able to supply the
required water volume against the (mostly low) pressure drop of the
boiler circuit; the pressure drop of the low loss header is negligible.
Subject to the water volume circulating in the generator circuit, the
respective residual head may be determined for sizing the internal pipe
diameters using the pump diagram; alternatively the variable speed
pump can be adjusted accordingly.

Adjusting the heating curves (slope and level)
The Vitotronic 200 controls the boiler water temperature (= flow temperature of the heating circuit without mixer) and the flow temperature
of the heating circuits with mixer (in conjunction with the extension kit
for one heating circuit with mixer) in weather-compensated mode. The
boiler water temperature is automatically boosted by between 0 and
40 K higher than the currently required set flow temperature (delivered
condition 8 K).
The flow temperature required to reach a specific room temperature
depends on the heating system and the thermal insulation of the building to be heated.
Adjusting the heating curves matches the boiler water temperature and
the flow temperature to these operating conditions.
Heating curves:
The upper boiler water temperature is limited by the temperature limiter
and the temperature set at the electronic maximum thermostat.
The flow temperature cannot exceed the boiler water temperature.
Heating systems with low loss header
When using a hydraulic separation (low loss header), connect a temperature sensor for use in the low loss header.

Regulations and Directives
The design and operational characteristics of the Vitodens gas condensing boilers from Viessmann meet the requirements of EN 297.
They are CE-designated.
They may be installed in sealed heating systems with permissible flow
temperatures (= safety temperatures) up to 100 ºC compliant with
EN 12828. The maximum flow temperature is approx. 15 K below the
safety temperature.
Observe all standards and guidelines applicable to the installation and
operation of this system in your country.
Only qualified contractors must carry out the installation, the mains gas
and flue gas connections, the commissioning, the electrical connection
as well as general maintenance and repair work.
The installation of a condensing boiler may need to be notified to and
approved by your local gas supply utility.

In some regions, permits may be required for the flue system and condensate drain into the public sewer.
In some countries, the relevant flue gas inspector and water authorities
must be informed prior to commencing the installation.
We recommend that you carry out maintenance and cleaning procedures annually. As part of the maintenance procedure, check the correct function of the entire system. Remedy any faults.
Condensing boilers must only be operated with specially designed,
tested and approved flue pipes.
Only recognised contractors may convert this boiler for use in countries
other than those stated on the type plate. That contractor must also
arrange the acceptance in accordance with the statutes of that country.
