Note: The Vitodens boiler has passed the zero inches vent

clearance to combustibles testing requirements

dictated by the Harmonized Standard ANSI Z21.13.

CSA 4.9.2000 and therefore is listed for zero

clearance to combustibles when vented with a

single wall special venting system (AL-29-4C

material). The zero inches vent clearance to

combustibles for the Vitodens boiler supercedes

the clearance to combustibles listing that appears

on the special venting system label.

Supply head pressure (water)

Flow rate

The Vitodens 200-W, B2HA is designed for closed loop,

forced circulation hot water heating systems only. Use

standard friction loss method for pipe sizing. Observe

boiler maximum and minimum flow rate limitations. If

system flow rate exceeds boiler maximum flow rate

(as stated above), falls below the minimum flow rate

or if system flow rate is unknown, Viessmann strongly

recommends the installation of a low-loss header.

An alternative method may be used, such as primary

secondary piping using closely spaced tees.

A low-loss header offers additional benefits not provided

by a pair of closely spaced tees. Viessmann therefore

strongly recommends and prefers the use of a low-loss

header over closely spaced tees. See pages 28 and 29

for low-loss header information. Once the low-loss header

is connected, the built-in low-loss header logic of the

Vitodens 200-W boiler ensures the required rt across the

system through the sensory communication between the

low-loss header and the boiler.

DHW Recirculation/ Boiler Mounting

Domestic Hot Water Recirculation

DHW recirculation lines increase the level of comfort and

convenience of the domestic hot water supply and reduce

water consumption.

These advantages directly derive from the immediate

availability of domestic hot water at all draw points.

Poor insulation of the DHW recirculation line, however,

can result in considerable heat loss. Viessmann therefore

recommends that effective insulation be provided and

used for DHW recirculation lines of 23 ft. (7 m) in length

or longer.

Condensate Connection/Neutralization Unit

Condensate Connection

Install the condensate drain pipe with a suitable gradient.

Discharge condensate from the boiler into the drainage

system, either directly or (if required) via a neutralization

unit (accessory).

Pipe ventilation must take place between the siphon trap

and the neutralization unit (if applicable).

Condensate Connection for Vitodens

200-W, models B2HA 112, 150

IMPORTANT

Condensate Drainage and Neutralization

The condensate formed both in the condensing boiler and

in the flue gas pipe must be discharged into the public

sewage system in accordance with all applicable local

regulations. The condensate produced by a gas-fired

heating system has a pH value between 3 and 4.

Some local codes may require the use of a separate

neutralization unit to treat the aggressive and corrosive

nature of the condensate. With a neutralization unit

installed, all condensate from the boiler and the flue gas

pipe enters into the neutralization unit where it is treated

and released into the public sewage system with a safe

pH value of above 6.5.

The use of neutralization granulate (performing the

neutralizing process) is dependent on the operation of the

heating system. To determine the required refill amount,

check granulate level several times during the first year

of operation. In some cases one granulate fill may last an

entire year.

Contact Viessmann to order a neutralization unit for the

Vitodens 200-W boiler.

See Viessmann Price List for order information.

The condensate discharge outlet to the drainage system

connection must be clearly visible. It must be installed

with a suitable gradient and provided with a stench trap.

If the condensate outlet of the Vitodens 200-W boiler is

lower than the drain, a condensate pump must be used.

Only corrosion-resistant materials must be used for

condensate drainage purposes (e.g. braided hose). Do not

use galvanized materials or materials containing copper for

piping, couplings etc.

The condensate drain must have a trap to prevent flue gas

leakage.

Please note that other requirements might apply

depending on local regulations and/or project-specific

details.

It is advisable to contact your local waterworks office

(authority responsible for waste water regulations)

well before commencing with the installation of the

neutralization unit in order to establish details of local

regulations that apply.

The following table shows the concentration of (effluent)

substances (e.g. heavy metals) contained in the waste

Boiler Control

Design and Function (continued)

Heating Curve Adjustment (slope and shift)

The control unit regulates the boiler water temperature

(= supply temperature of heating circuit without mixing

valve) and the supply temperature of the heating circuit

with mixing valve (in conjunction with the accessory kit

for a heating circuit with mixing valve) according to the

outdoor temperature. The boiler water temperature is

automatically raised by 0 to 72 F / 0 to 40 K higher

than the currently required set supply temperature

(in the factory default setting the differential temperature

is 14.4 F / 8 K). See Start-up/Service Instructions for

coding address “9F” in coding level 2.

The supply temperature that is required to achieve a

given room temperature depends on the heating system

and the thermal insulation of the building that is being

heated.

The adjustment of the two heating curves is used to

match the boiler water temperature and the supply

temperature to these conditions. The boiler water

temperature is limited upwards by the fixed high limit

and the temperature set for the electronic high limit.

The supply temperature cannot rise above the boiler

water temperature.

Low-Loss Header

When used in conjunction with the Vitodens 200-W

boiler, the low-loss header acts as hydraulic break,

decoupling boiler and system circuits from each other.

It is recommended to use the low-loss header in

applications in which the total system flow rate exceeds

the maximum (or minimum) boiler flow rate.

For maximum boiler flow rates, see page 9 of this manual.

Viessmann strongly recommends the use of a low-loss

header in cases where the system head and flow rates

are unknown.

The temperature sensor connection [TS] typically located

at the top of the low-loss header ensures low return

temperatures to the Vitodens 200-W boiler at all times,

increasing operational efficiency.

In addition, the low-loss header helps eliminate air and

debris [D] from the heating system.

See illustrations for design and principle of operation.

The low-loss header is available in the following sizes.

Select the size based on the maximum system flow rate

of your application.

The combustion management system utilizes the physical

correlation between the level of the ionization current

and the air factor λ. For all gas qualities, the maximum

ionization current results with air factor λ.

The ionization signal is evaluated by the combustion

management system, and the air factor is adjusted to

between λ=1.24 and 1.44. This range provides for an

optimum combustion quality. Thereafter, the electronic

gas valve regulates the required gas volume based on the

prevailing gas quality.

To check the combustion quality, the CO2 content or the

O2 content of the flue gas is measured. The actual values

enable the prevailing air factor to be determined.

The relationship between the CO2 or O2 content and

air factor λ is illustrated in the table below.

To achieve an optimum combustion control, the system

regularly performs an automatic self-calibration; also after

a power failure (shutdown). For this, the combustion is

briefly regulated to max. ionization current (equals air factor

λ=1). The automatic calibration is performed shortly after

the burner starts and lasts approximately 5 seconds.

During the calibration, higher than normal CO emissions

may occur briefly.

The combustion management system can also be

calibrated manually, e.g. after maintenance or service

work (coding address “85”, see Service Instructions).

The Vitodens 200-W, B2HA boilers come equipped with Lambda Pro, the industry’s first intelligent combustion

management system.

Installation Examples

Please note that in the following piping layout examples, all pumps are field supplied.

IMPORTANT IMPORTANT

The examples on the following pages depict possible

piping layouts of the Vitodens 200-W boiler equipped with

Viessmann System Technology.

For boiler and tank combinations, please install only

feasible combinations listed in the Viessmann Price List.

Please note that the following examples are simplified

conceptual drawings only!

Piping and necessary componentry must be field verified.

A low water cut-off (LWCO) must be installed where

required by local codes.

Proper installation and functionality in the field is the

responsibility of the heating contractor.

DHW supply and return piping between boiler DHW

connections and the Viessmann DHW tank connections,

shall be a minimum of 1¼” (for models B2HA 45 to 100)

and 2 in. (for models B2HA 112 to 150) DHW connection

outlet sizes provided on the boiler and the DHW tank).

This will ensure the residual head of the field supplied

pump is fully utilized to overcome the resistance of the

DHW heat exchanger coil and to provide sufficient water

flow to the boiler heat exchanger.

In non-Viessmann DHW tank applications, perform, in

addition to the above, accurate calculations for DHW

tank coil pressure drop versus boiler pump (field supplied)

residual head to ensure sufficient water flow to the boiler

heat exchanger. Failure to heed the above instructions

may cause boiler short-cycling and inadequate DHW

supply.

WARNING

If a DHW storage tank other than a Viessmann

Vitocell 100 or 300 tank is used, the installer must

verify proper operation of the Viessmann DHW tank

temperature sensor with the original manufacturer

of the tank. Viessmann strongly recommends the

installation of a temperature tempering valve in the

DHW supply line.

Hydraulic Connection

System design

Viessmann condensing boilers can generally be installed

in any pumped hot water heating system (closed system).

The circulation pump is an integral part of the appliance.

Minimum system pressure 15 psi (1.0 bar).

The boiler water temperature is limited to 180º F (82º C).

To minimise distribution losses, we recommend that

you size the heat distribution system to a max. flow

temperature of 158º F (70º C).

For apartments with less than 860 ft2 (80 m2) living

space or for low energy houses with low heat demand

we recommend, due to the immediate capturing of the

room-influencing factors, the utilisation of the Vitodens

with a constant temperature control unit in conjunction

with the Vitotrol 100.

To reduce burner cycling in low energy houses with a

correspondingly low heat demand, we recommend the

use of a low loss header.

System separation is required of underfloor heating

systems employing non-oxygen diffusion barrier tubing.

All components on the secondary side of the heat

exchanger must be made of corrosion-resistant materials.

Sizing of field-supplied pump P is critical for proper boiler

operation in this system layout. See page 9 for the supply

head pressure drop of the boiler. An undersized pump

may cause short-cycling and/or improper operation of the

boiler. Viessmann STRONGLY recommends using a low-

loss header and a boiler pump in this system layout.

System Design Considerations

IN THE COMMONWEALTH OF MASSACHUSETTS...

- this product shall be installed by a licensed plumber or

gas fitter.

- the flexible connector (if used) cannot exceed 36”.

- any level type shutoff used must be of tee handle

type.

Boiler location

As a direct vent appliance, the Vitodens 200-W can

be installed for room air independent operation (sealed

combustion) regardless of size and ventilation method

of the room in which it is located.

The Vitodens 200-W can be installed, for example, in

the main living area of a house, in non-ventilated utility

rooms, cupboards, closets and alcoves with no clearance

required from combustible materials, as well as in attics

with a direct outlet for the flue gas/fresh air system.

Follow all local and national codes.

Flue gas system

Viessmann PPS (Polypropylene) concentric flue gas/

fresh air systems for room air independent operation

(sealed combustion) and side wall venting are tested

to ANSI Z21.13 - CSA 4.9 - 2000 standards and are

certified together with the Vitodens 200-W boiler as a

constructional unit.

The Vitodens 200-W boiler may also be vented vertically,

using an AL29-4C® special stainless steel, single-wall, room

air dependent venting system (UL listed for category IV).

For a more detailed description of the direct vent and

single-wall vent system, please refer to the Vitodens 200-W

Venting System Installation Instructions.

Flue gas temperature protection

Flue pipes used for the Vitodens 200-W are suitable for

max. flue gas temperatures of up to 230° F (110° C).

No flue gas temperature protection is required as the

maximum permissible flue gas temperature is not

exceeded in any operating condition or in the event of

malfunctioning.

Low water cut-off

A low water cut-off may be required by local codes.

If the boiler is installed above the radiation level, a low

water cut-off device of approved type must be installed

in all instances. An approved type low water cut-off

device must be provided by the heating contractor.

Do not install an isolation valve between the boiler and

the low water cut-off.

Water connections

Vitodens 200-W boilers can be used in any fully pumped

hot water heating system.

Minimum system pressure is 0.8 bar (12 psig).

Chemical corrosion protection products

Corrosion does not typically occur in sealed heating

systems which have been correctly installed and are

correctly operated.

Many manufacturers of plastic pipes recommend the

use of chemical additives. In this case, only those

commercially available corrosion protection products

approved for boilers with domestic hot water heating

via single-wall heat exchangers (instantaneous plate

heat exchangers or DHW tanks) must be used.

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. Maximum antifreeze

content is 50% for the Vitodens 200-W boiler. 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.

Advise system operator/ultimate owner that system is

filled with a glycol mix. The heating contractor must

provide a MSDS (Material Safety Data Sheet) for the

antifreeze used to the system operator/ultimate owner.

Vitodens 200-W B2HA 100 to 150 Technical Data System Design

System Design Considerations (continued)

System layout

■ The max. boiler water temperature for space heating

and DHW production is for model B2HA 100.

To minimize distribution losses, Viessmann

recommends that the heating and domestic hot water

systems be based on a maximum boiler supply

temperature of 158° F (70° C).

■ Due to the low return temperatures required for gas

condensing, no mixing valves should be used in the

heating circuit whenever possible. If mixing valves

are required, e.g. for multi-circuit systems or

underfloor heating systems, only 3-way mixing valves

must be used.

Do not use 4-way mixing valves with condensing

boilers.

Underfloor heating systems

For underfloor heating systems Viessmann recommends

the use of plastic tubing with an oxygen diffusion barrier

in order to prevent the diffusion of oxygen through

tubing. If plastic tubing without an oxygen diffusion

barrier is used in underfloor heating systems, Viessmann

recommends that such systems be separated from the

boiler with a heat exchanger.

Underfloor heating systems and heating circuits

containing a very large volume of water must be

connected to the boiler via a 3-way mixing valve; please

refer to the applicable installation example in this manual.

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.

Warranty

Our warranty does not cover damages resulting from

the following:

- installation or service by unqualified and unlicensed
