Product Information

2VITOROND 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:

HEfficient and environmentally friendly

operation due to modulated boiler water

temperatures.

Combustion efficiency:

- oil 88%.

.......................................................

- gas 85%......................................................

HEutectoplex 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.

HLow-emission combustion through

triple-pass design.

HProblem-free transport into

difficult-to-access boiler rooms due to

sectional construction and low weight of

individual sections.

HSimple, 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.

HEasy 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.

HEfficient and safe operation of the heating

system with Vitotronic or Dekamatik

digital boiler and heating system control.

Tailored to suit every requirement, these

controls cover all known control strategies

and applications.

HEconomical 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 applications requiring larger

quantities of hot water.

supplied burner dimensions.

Note

For mounting burners with blast tube

diameters of 150 mm / 6” to

(refractory material) can be cut to the

required size.

The blast tube must protrude from the

thermal insulation on the boiler door.

Low temperature protection packages from

Viessmann are required for Rondomat

boilers. A 30% Boiler Flow Package is

typically utilized in single-boiler installations.

100% Boiler Flow Packages are utilized in

single- and multiple-boiler installations.

Selection of the correct package depends on

the characteristics of the heating system,

and the degree of control necessary to

protect the boiler. Contact Viessmann for

assistance.

Technical Data

10 VITOROND 200, VD2

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 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.
