Product Information
2 VITOROND 200, VD2
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 reliability and a long service
life.
The benefits at a glance:
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 Problem-free transport into
difficult-to-access boiler rooms due to
sectional construction and low weight of
individual sections.
H Efficient and environmentally friendly
operation due to modulated boiler water
temperatures.
Combustion efficiency up to:
- oil 88.1%

H Low-emission combustion through
triple-pass design.
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 Problem-free cleaning access facilitated by
a hinged (left or right) swing-open
combustion chamber door, allowing easy
access to all three heat exchanger passes
from boiler front, reducing side clearance.
H Economical and safe operation of the
heating system with Vitotronic or
Dekamatik digital boiler and heating
system control. Tailored to every
requirement, this control covers all known
control strategies and applications.
H Economical and hygienic DHW production
with indirect-fired Vitocell 100 steel or
Vitocell 300 stainless steel tanks.
Tanks may be combined into multiple-tank
batteries for applications requiring larger
quantities of hot water.

Waterside Flow
The Vitorond 200 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. When a balancing valve is used for
proper balancing and water flow through the boiler, the valve
should be installed 5 pipe diameters from any fittings and 10
pipe diameters from circulation pumps to allow for laminar
flow.
The consulting engineer or contractor 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.

System Design Considerations
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 burner
When used with the Dekamatik or Vitotronic
control, the following minimum heating
outputs are 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
a
s a Category I and III appliance and must
be vented accordingly.
Chimney
For proper operation of the Vitorond 200,
V
D2 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 system 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. The chimney
connection length between the boiler vent
pipe collar and the chimney must be
installed with 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.
Chimney (continued)
W
hen 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 barometric draft 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 natural gas or propane applications, use
a double-acting type.
For #2 fuel oil applications, use a
single-acting type.
Barometric draft regulator 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.
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.
Venting option #2 (Category III)
The Vitorond 200 boiler is a C
ategory III
positive pressure non-condensing boiler.
Each boiler must be vented individually.
The vent system must be properly designed
and suitable materials must be selected. The
chimney must be gas tight.
Combustion air supply
The boiler must not be located in areas or
r
ooms 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 combustion air must not be
contaminated with any amount of the above
mentioned chemicals.
Boiler should never be installed in areas
where excessive dust, high humidity, or risk
of frost exist. Ensure adequate ventilation
and supply of fresh combustion air.
Consult Viessmann with uncertainties 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 when installing a
round duct to supply combustion air from
the outside.
Warranty
Our warranty does not cover damages
r
esulting 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 adjustable high
limit to increase 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 boiler 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 antifreeze 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 exceed 50%
antifreeze mix ratio and 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 system 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 non-oxygen diffusion barrier tubing
separated from the boiler with a heat
exchanger. Viessmann recommends the use
of underfloor plastic tubing with an oxygen
diffusion barrier.
Burner manufacturer
Weishaupt or Riello.
Burner/Gas train approval
Standard approvals are CSA (for Canada)
and UL (for U.S.). IRI and FM approved
equipment is also available - please inquire.
Electrical requirements
Weishaupt WG, WL, L, RL, G, GL and
WM-G(L) RGL Series burners listed on page
15 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. Size 7 burners are not
available in 120 VAC single-phase
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.
