*6 Based on maximum input rate.
*7 Requires 1 inch (25 mm) tubing. See the Installation Instructions of the Vitodens 200-W, B2HA for details.
*8 For side wall vent installations (coaxial system):
Do not exceed max. equivalent length specified in the Installation Instructions of the Vitodens 200-W, B2HA
Venting System.
Do not attempt to common-vent Vitodens 200-W with any other appliance.
Side wall co-axial vent installation must include Viessmann protective screen!
For details refer to the Installation Instructions for the Vitodens 200-W, B2HA Venting System.
For information regarding other Viessmann System Technology componentry, please reference documentation
of respective product.
Note: For high altitude installation at 10,000 ft. the input for model B2HA 19-80 will have an altitude
de-ration of 21%.

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.

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 32 and 33
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 t across the
system through the sensory communication between the
low-loss header and the boiler.

Pump Information
Heating Circuit / Boiler Pumps
Viessmann offers a variety of Grundfos heating circuit/
boiler pumps which meet typical Vitodens system
installation requirements (see “Heating circuit pump
(field supplied)” or “Boiler pump (field supplied)” in the
Installation Examples starting on page 35). See tables
below for recommended pumps. Refer to the graphs on
page 10 and 11 for the proper waterside boiler friction
loss calculations. The following pumps have been selected
based on boiler heat exchanger head loss and boiler piping
to a low-loss header.
IMPORTANT
Pump selection must be based on accurate system flow
and pressure drop calculations (includes DHW sizing).

IMPORTANT
Vitodens 200-W boilers can be used in conjunction
with the stand-alone DHW storage tanks offered by
Viessmann.
All Viessmann DHW storage tanks sold in North America
are available in “Vitosilver” finish only.
Size and select the DHW storage tank based on the
forecasted DHW consumption of the building in question.
For further technical information on DHW storage tanks,
see the Vitocell-V Technical Data Manuals.
For the connection of a stand-alone DHW tank, installation
fittings (field supplied), an external circulating pump for
DHW production (field supplied) and a DHW temperature
sensor (optional equipment, see Viessmann Price List for
order information) are required.

DHW Recirculation
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.

Wall Mounting
Mounting Bracket
1. Remove the external accessories connection box
cover.
2. Loosen the screws at the bottom of the boiler
(do not remove completely).
3. Remove the front encloser panel (lift up and pull
away from the boiler).
4. Mount boiler onto the mounting bracket and connect
boiler to the installation fittings.
5. Ensure the boiler is securely mounted.
CAUTION
Whichever mounting method is used, ensure that the
bracket is tightly and securely fastened to wall. Failure
to secure boiler properly could cause boiler to loosen,
posing a severe safety hazard.
Fitting the wall mounting bracket
See the installation instructions applicable to the
mounting bracket on each type of material.
Models B2HA 19, 28, 35
CAUTION
The boiler must be level both vertically and horizontally
to ensure proper draining of the condensate.
