Product Information
VITOROND 200
The modular sectional cast iron design of
the Vitorond 200, VD2 allows for
problem-free transport into
difficult-to-access boiler rooms and permits
easy assembly.
The triple-pass design ensures clean,
low-emission combustion, while the
Eutectoplex heat exchanger surface
guarantees economical energy consumption,
high operational r eliability and a long service
life.
The benefits at a glance:
H Efficient and environmentally friendly
operation due to modulated boiler water
temperatures.
Combustion efficiency:
- oil 88%.
.......................................................
- gas 85%......................................................
H Eutectoplex heat exchanger surface for high
operational reliability and a long service life.
The homogeneous structure of the
Eutectoplex special gray cast iron ensures
uniform heat transfer, minimizing stress
fractures and counteracting the formation of
condensate.
Shape and geometry of the cast iron
sections, excellent water flow characteristics
and uniform temperature distribution further
increase the level of operational reliability.
H Low-emission combustion through
triple-pass design.
H Problem-free transport into
difficult-to-access boiler rooms due to
sectional construction and low we ight of
individual sections.
H Simple, quick assembly of the individual
cast iron sections is achieved with a
double-groove seal fit system for the flue
gas passageways. The gasket seal is
secured in place by the double groove,
and therefore not subject to mechanical
stresses.
H Easy cleaning access facilitated by a
hinged (le ft or right) swing-open
combustion chamber door, allowing easy
access to all three heat exchanger passes
from boile r front, reducing side cleara nce.
H Efficient and safe ope ration of the heating
system with Vitotronic or Dekamatik
digital boiler and heating system control.
Tailored to s uit every requirement, these
controls cover all know n control strategies
and applications.
H Economical and hygienic domestic hot
water production with indirect-fired
Vitocell 100 steel or Vitocell 300 stainless
steel tanks.
Tanks may be combined into multiple-tank
batteries for a pplications requiring larger
quantities of hot water.

Technical Data
Waterside Flow
The Vitorond 200 boiler is designed for closed loop, forced
circulation, hot water heating systems only.
The recommended water flow rate through the Vitorond 200
is based on a temperature difference of between 20°F and
40°F / 11°C and 22°C (see table below). When a balancing
valve is used for proper balancing and water flow through the
boiler, the valve should be installed 5 pipe dia meters from any
fittings and 10 pipe diameters from circulation pumps to allow
for laminar flow.
The consulting engineer or c ontractor should review the
system design if more balancing valves are required to
properly balance the system.
Viessmann can supply TA (Victaulic) balancing valves upon
request. The balancing should be carried out by a certified
balancing firm prior to boiler start-up. Please contact
Viessmann for your closest certified balancing firm.

Burner calibration
With 2-stage and fully modulating burners,
ensure that the chimney is compatible with
the lower flue gas temperatures associated
with partial load conditions set on the
burner.
2-Stage burne r
When used with the Dekamatik or Vitotronic
control, the following minimum heating
outputs ar e applicable to protect the boiler:
- 60% of outputs stated in the Technical
Data table on page 4.
Fully modulating burner
The minimum boiler water temperature is:
– 140°F / 60°C with oil,
– 149°F / 65°C with natural gas.
Set the return temperature elevation system
to maintain a minimum value of 127°F /
53°C.
Venting
The Vitorond 200, VD2 boiler is approved
as a Category I appliance and must be
vented accordingly.
CAUTION
The Vitorond 200, VD2 boiler is not
approved for side wall venting.
Chimney
For proper operation of the Vitorond 200,
VD2 boiler, all products of combustion must
be safely vented to the outdoors, while
ensuring that flue gases do not cool
prematurely.
It is critical that the chimney s ystem be
properly designed to handle the relatively
cool flue gas temperatures produced by the
Vitorond 200, VD2 boiler.
If the chimney system lacks sufficient
insulation and/or the chimney diameter is
too large, corrosive and damaging
condensation will result due to flue gases
cooling too quickly. If a calculated chimney
diameter lies between two values, the larger
diameter should be selected.

VITOROND 200, VD2 13
Chimney (continued)
The chimney connection length between the
boiler vent pipe collar and the chimney must
be installed w ith insulation.
Vent pipe collar diameter does not
automatically indicate vent/chimney size.
We recommend consulting a reputable
chimney installer for advice in
project-specific circumstances.
When installing the Vitorond 200, VD2
boiler, it is necessary to install a barometric
draft regulator in the chimney/vent for
proper operation of the boiler.
Install the barome tr ic dra ft regulator within
5 to 7 ft. / 1½ to 2 m from the breeching
outlet located at the rear of the boiler.
Barometric draft regulator type
For natura l gas or propane applications, use
a double -acting type.
For #2 fuel oil applications, use a
single-acting type.
Barometric draft r egulator diameter
The barometric draft regulator must be the
same diameter opening as the chimney for
which the vent is sized.
For example , a 14” chimney would require a
14” barometric draft regulator. Do not size
the barometric draft regulator to the
breeching outlet of the boiler, unless the
chimney is also intended to be of that
diameter.
IMPORTANT
The size of the flue gas outlet on the boiler
does not automatically determine the
horizontal breeching, or the actual chimney
diameter. The chimney size must be
designed for the actual boiler model and its
input.
Barometric draft regulator
Combustion air supply
The boiler must not be located in areas or
rooms where chemicals containing chlorine,
bromine, fluorine, or other corrosive
chemicals are stored. Examples include
refrigerants, bleach, paint, paint thinner, hair
spray, cleaning solvents, water softener
salt, etc. The combus tion air must not be
contaminated with any amount of the above
mentioned chemicals.
Boiler should never be installe d in areas
where excessive dust, high humidity, or risk
of frost exist. Ensure adequate ventilation
and supply of fresh combustion air.
Consult Viessmann with unc ertainties in
regard to a suitable boiler installation
location.
This boiler/burner unit needs clean fresh air
for safe operation. Provisions for
combustion and ventilation air must be
made at time of installation. For oil-fired
boilers, use the “Installation Code for Oil
Burning Equipment CAN/CSA-B139”
(Canada), or NFPA 31 (USA). For gas or
propane installations, use the “Natural Gas
Installation Code CAN/CSA-B149.1 or
B149.2” (Canada), or “National Fuel Gas
Code ANSI Z223.1” (USA), and/or
provisions of local codes.
The sizing methods outlined in the above
codes should be used w hen ins talling a
round duct to supply combustion air from
the outside.
Warranty
Our warranty does not cover damages
resulting from the following:
– Corrosion caused by flue gas condensation
due to low boiler water and/or return
water temperatures.
– Operation with contaminated fill and
supplementary feed water.
System layout
The boiler water temperature limit is factory
set to 167°F / 75°C.
The boiler water temperature limit can be
increased by altering the adjus table high
limit to increas e the supply water
temperature.
To minimize piping losses of the system,
however, Viessmann recommends that the
radiation and domestic hot water production
in the system be designed for a 158°F /
70°C boiler supply water temperature.

System Design Considerations (continued)/Burner Alternatives
Water quality
Treatment for boile r feed water should be
considered in areas of known problems,
such as where a high mineral content and
hardness exist. In areas where freezing
might occur, an antifreeze may be added to
the system water to protect the system.
Please adhere to the specifications given by
the antifreez e manufacturer. Do not use
automotive silicate-based antifreeze. Please
observe that an antifreeze/water mixture
may require a backflow preventer within the
automatic water feed and influence
components such as diaphragm expansion
tanks, radiation, etc. A 40% antifreeze
content will provide freeze-up protection to
-10°F / -23°C. Do not use antifreeze other
than specifically made for hot water heating
systems. System also may contain
components which might be negatively
affected by antifreeze. Check total s ystem
frequently when filled with antifreeze.
Follow the instructions of antifreeze
manufacturer.
Oxygen diffusion barrier
underfloor tubing
The boiler warranty does not cover leaks
resulting from corrosion caused by the use
of underfloor plastic tubing without an
oxygen diffusion barrier. Such systems must
have the tubing without oxygen diffusion
barrier separated from the boiler with a heat
exchanger. Viessmann recommends the use
of underfloor plastic tubing with an oxygen
diffusion bar rier.
Burner manufacturer
Weishaupt or Riello
Burner/Gas train approval
Standard approvals are CSA (for Canada)
and U L (for U.S.). IRI and FM approved
equipment is also a vailable - please inquire.
Electrical requirements
Weishaupt W Series bur ners are available in
120 VAC, single-phase, in a 60 Hz
configuration. L, G, and GL Series burners
listed below are available in 120 VAC single
phase, 208 VAC three-phase, 460 VAC
three-phase, or 575 VAC three-phase, all in
60 Hz configuration. It is generally
acceptable to use voltages within ten
percent of the supply voltage. Available
voltage inside boiler room must be provided
at time of order. Ensure appropriate
disconnect means and overcurrent
protection.
Natural gas pressure
Natural gas pressures and heating values as
provided by the gas utilities vary greatly
across North America. Select the
appropriate gas train accordingly. Low
pressure gas trains have a maximum input
of 14 ”w.c .; high pressure gas trains have a
maximum pressure of 5 psig. Minimum gas
pressures apply - please inquire. Gas
pressures and heating values at site must be
provided at time of order.
Factory prewired components
Custom factory prewiring by Viessmann
ensures optimal functionality, compliance
with regional r equirements, and ease of
installation in the field. Pricing provided by
Viessmann includes all necessary hardware
items such as junction pane l, burner power
supply, boiler door safety switch (where
necessary), and all essential pressure
switches, as well as interconnection with
conduit between control and burner.
Electrical drawings provided upon product
delivery.
