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 heating 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 eight boilers and a heating output up to 840
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 seasonal efficiency [to DIN] up to 98 % (Hs) [gross
cv]/109 % (Hi) [net cv].
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 that, subject to the
prevailing heat demand, either one boiler modulates or all four boilers
operate concurrently.
For creating cascade systems, we offer perfectly matching system
components, e.g. control units with up to four appliances, fully insulated hydraulic cascades and flue gas headers.
Recommended applications
High heating 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 apartment buildings, central heating plants for terraced
houses, office buildings and administration premises – particularly
suitable for attic heating centres
■ Heating of public buildings, such as sports centres and multi purpose
halls, schools, kindergartens
■ Suitable for installation in basement boiler rooms, on single floors or
in the attic
■ Durable and efficient through the Inox-Radial heat exchanger
■ Modulating MatriX cylinder burner with a long service life thanks to
stainless steel MatriX mesh – resistant to high temperature loads
■ Easy-to-operate Vitotronic control unit with plain text and graphic
display
■ The programming unit part of the control unit can also be fitted on a
wall mounting base (accessory)
■ Lambda Pro Control combustion controller for all gas types – saving
costs by extending the inspection intervals up to 3 years [in Germany]
■ Quiet operation through low fan speed
Delivered condition
Wall mounted gas condensing boiler with Inox-Radial heat exchanger,
modulating MatriX cylinder burner for natural gas and LPG to DVGW
Code of Practice G260 [Germany], plus wall mounting bracket.
Fully plumbed and wired. White epoxy-coated casing.
Packed separately:
Vitotronic 100 for constant temperature mode
or
Vitotronic 200 for weather-compensated operation.
Preset for operation with natural gas. A conversion within gas groups
E/LL is not required. The conversion to LPG is made at the gas valve
(a conversion kit is not required).

Calculation values for sizing the flue system to EN 13384.
Flue gas temperatures measured as gross values at 20 °C combustion air temperature.
The flue gas temperature at a return temperature of 30 °C is significant for the sizing of the flue system.
The flue gas temperature at a return temperature of 60 °C is used to determine the application range of flue pipes with maximum permissible
operating temperatures.

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.

For details regarding DHW cylinders, see the technical guide to the
Vitodens up to 35 kW, or separate datasheets.
Design information
4.1 Siting, installation
Siting conditions for open flue operation (appliance type B)
(Type B23 and B33)
In rooms where air contamination through halogenated hydrocarbons can occur, such as hairdressing salons, printing shops, chemical
cleaners, laboratories, etc., install the Vitodens only as a balanced flue
system.
If in doubt, please contact us.
Wall mounted boilers should not be installed in areas subject to very
dusty conditions.
A ventilation air filter is available as an accessory for operation during
the building phase. This protects the appliance against excessive dust
loads.
The installation location must be kept free from frost and must be adequately ventilated.
Provide a condensate drain and a discharge pipe for the safety valve
in the installation room.
The maximum ambient temperature of the system should not exceed
35 ºC.
If these instructions are not observed, any consequential loss directly
related to any of these causes is excluded from our warranty.
For further details, see the technical guide on flue systems for the
Vitodens.
Installation room (up to 50 kW)
Permissible:
■ Boiler installation on the same floor
■ Adjacent rooms with interconnected room air supply (larders, basements, utility rooms, etc.)
■ Attic rooms, but only with adequate minimum chimney height to DIN
18160 – 4 m above inlet (negative pressure operation).
Not permissible:
■ Stairwells and common hallways; exception: Detached and twofamily homes of low height (top edge of floor in the top storey <
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.
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 mains isolator outside the installation room.
Combustion air apertures
Gas equipment with a total rated heating 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 heating 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 heating output 180 kW
150 cm2 + 130 × 2 cm2 = 410 cm2 or 2 × 205 cm2.
The combustion air vents should be at least 410 cm2 or 2 × 205 cm2.
Connection on the flue gas side
(for further details, see the technical guide "Flue systems for the
Vitodens")
The connection piece to the chimney should be as short as possible.
Therefore position the Vitodens as close 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 do not
exceed 85 ºC at any point.
Extractors
When installing appliances with extraction to the outside (cooker
hoods, extractor fans etc.), ensure that air extraction will not create
negative pressure inside the installation room. A return flow of flue gas
could result if the ventilation system and the Vitodens were operated
simultaneously. In such cases, install an interlock circuit.
For this, internal extension H2 (accessory) can be used. This switches
the extractors off when the burner is started.
Multi boiler systems with pressurised flue systems
The Vitodens 200-W multi boiler systems with common pressurised
flue systems are designed for open flue operation (type B).
Siting conditions for balanced flue operation (appliance type C)
5822 432 GB
The Vitodens can be installed as appliance type C13x, C33x, C43x, C53x,
C63x or C83x 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 sited in recreation rooms, in other living spaces,
in ancillary rooms without ventilation, in cupboards (open at the top)
or recesses, without maintaining minimum clearances to combustible
parts, or in attic rooms (pitched attics and the long pane of the roof)
where the balanced flue pipe can be directly routed through the roof.
Since the flue pipe connection 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 systems for the Vitodens").
The installation room must be free from the risk of frost.
Provide a condensate drain and a discharge pipe 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
mains isolator outside the installation room.
Appropriate ventilation air and extract air apertures are required in
accordance with TRGI (see the technical guide on flue 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 (IP rating:
IP X4 D, splashproof)
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.

Power supply for accessories
The power supply for accessories can be connected directly to the
control unit.
This connection is switched by the system ON/OFF switch.
If the total system current exceeds 6 A, connect one or more extensions via an ON/OFF switch directly to the mains supply.
Where the boiler is installed in a wet area, the power supply connection
of accessories must not be made at the control unit.
VITODENS 200-W

The power supply must comply with the requirements of your local
power supply utility and current VDE [or local] regulations.
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 proven 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 a registered gas fitter.
Connect and size the mains gas according to TRGI 2008 or TRF 1996
[or local regulations].
Max. test pressure 150 mbar.
We recommend the installation of a gas filter compliant with DIN 3386
in the gas line.
Thermally activated safety shut-off valve
According to paragraph 4, section 5 of the FeuVo 2008 [or local regulations], thermally activated shut-off equipment must be installed in
gas combustion equipment or in gas lines immediately upstream of the
gas combustion equipment, which will shut off the gas supply if the
external temperature exceeds 100 ºC. 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.
Sizing recommendation, gas flow limiter
In supply areas with HIB below 8.6 kWh/m3 and gas appliances compliant with category I2N, determine a fictitious rated heat input. This
fictitious rated heat input results from the rated heat input (QNB) of the
appliance, multiplied by a factor of 1.23 (ratio HIB 8.6/7.0). Select the
gas flow limiter and size the pipework in accordance with the TRGI
2008 [or local regulations] using this fictitious rated heat input.

Condensate drain and neutralisation
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.
Code of Practice ATV-DVWK-A 251 "Condensate from condensing
boilers", which is generally based on the local waste water regulations
[in Germany], defines the conditions for draining condensate from
condensing boilers into the public sewage system.
The composition of condensate drained from Vitodens condensing
boilers meets the requirements specified in Code of Practice ATVDVWK-A 251.
The condensate drain pipe to the sewer connection must be able to
be inspected.
It must be installed with a continuous fall and must contain a stench
trap. Also provide a suitable facility for sampling.
Condensate drain pipes must only be made from corrosion-resistant
materials (e.g. reinforced hose).
Never use any galvanised materials or those containing copper
for pipes, connection pieces 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 heating output of 200 kW, the condensate from a gas
condensing boiler can generally be introduced into the public sewage
system without prior neutralisation.
Also ensure that your domestic drainage systems are made from
materials that are resistant to acidic condensate.
According to 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

VITODENS 200-W
Design information (cont.)
The Vitodens can (if required) be supplied with a separate neutralising
system (accessory). Any condensate is piped to and treated in the
neutralising system.
The condensate drain pipe to the sewer connection must be able to
be inspected. It must be installed with a fall and stench trap on the
sewer side, and must provide a suitable facility for sampling.
Install a condensate lifting pump if the Vitodens has been installed
below the waste water anti-flooding level.
Condensate lifting pumps are available as accessories (see the Vitoset
pricelist).
Since the consumption of neutralising 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.

Chemical anti-corrosion agents
Corrosion is generally avoided in correctly installed and operated
sealed unvented 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 Directive 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.
Even with condensing boilers, connect underfloor heating systems and
heating circuits with a very large water content (>15 l/kW) to the boiler
via a 3-way mixer; see technical guide "Control of underfloor heating
systems" or the relevant sample applications.
Install a temperature limiter in 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 discharge pipe 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 indicator can be omitted for boilers
up to 300 kW, as long as heating can be reliably prevented in the case
of water shortage.
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.
36
VIESMANN
Attic heating centre
The installation of a low water indicator specified as compulsory to EN
12828 is not required when installing the Vitodens in an attic heating
centre.
The Vitodens condensing boilers are protected against water shortage
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 water quality.
■ Fill and top-up 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):

■ For systems with a specific system volume in excess of 20 litres/kW
heating output, use the output of the smallest boiler in multi boiler
systems.
■ 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 resulting from these causes.
When engineering the system, observe the following:
■ Install shut-off valves in different sections. This prevents the need
for draining all the heating water in the case of repairs or system
expansion.
■ In systems > 50 kW, install a water meter to record the volume of
the fill and top-up water. Record the amount of water filled into the
system and the water hardness.
Operating information:
■ Commission the system step by step, starting with the lowest boiler
output and a high heating water flow rate. This prevents a localised
concentration of limescale deposits on the boiler heating surfaces.
■ In multi boiler systems, start all boilers simultaneously to prevent the
entire limescale deposit settling in the heat transfer area of just one
boiler.
■ During expansion or repair work, only drain the necessary pipework
sections.
VITODENS 200-W
5822 432 GB
System design
Viessmann condensing boilers can generally be installed in any fully
pumped hot water heating system (sealed unvented system).
Connection sets with an integral circulation pump are available as
accessories.
Minimum system pressure 1.0 bar.
The boiler water temperature is limited to 82 ºC.
To keep distribution losses as low as possible, we recommend sizing
the heat distribution system for a maximum flow temperature of
70 ºC.
Design information (cont.)
■ Where water treatment is required, treat even the first fill of the heating system prior to commissioning. This also applies to any subsequent filling, e.g. when adding top-up water, after a repair or after
system expansion.
■ Filters, dirt traps and other discharge or separating facilities in the
heating water circuit must be checked, cleaned and activated more
frequently after commissioning or recommissioning, and later on as
required, subject to the water treatment applied (e.g. water softening).
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.
Multi boiler systems
We recommend the installation of a low loss header in multi boiler
systems. For this, order the low loss header that is available as an
accessory. See page 28 and the Viessmann pricelist.
Losses resulting from the use of third party low loss headers are excluded from our liability.
On-site safety equipment should comply with EN 12828.
Information on sizing the plate heat exchanger:
■ The pressure drop in the plate heat exchanger must be lower than
the lowest pressure drop of connected heating circuits.
■ Fit a dirt trap on the secondary side of the plate heat exchanger.
■ When sizing, take the temperature differential of the plate heat
exchanger into account (max. flow temperature in a multi boiler system with Vitodens 200-W: 80 °C)
As an alternative to the low loss header, a suitably sized plate heat
exchanger may be used to provide system separation. In that case,
the flow temperature sensor should be arranged on the secondary side
of the plate heat exchanger. See the following system example.

Low loss header
Application

Design rules for system hydraulics:
■ When balancing the low loss header, adjust the flow rate on the
equipment side to 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. flow rate that may
occur in the system as a whole.
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 in an individual case
is greater than the values shown in the table below.
Vitodens 200-W, 17 - 45 kW
Vitodens 200-W, 17 - 60 kW

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 boiler 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.

set flow temperature
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 system flow temperature
and the heating circuit flow temperature to these conditions.

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 unvented heating systems with permissible flow temperatures (= safety temperatures) up to 100 ºC to
EN 12828. The maximum achievable 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.
VITODENS 200-W
In some regions, permits may be required for the flue system and condensate drain into the public sewage system.
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 approval in accordance with the statutes of that country.
