*4 Measured flue gas temperature with a combustion air temperature of 68° F (20° C).
*5 Based on maximum input rate.
*6 Requires 1 inch (25 mm) tubing. See the Installation Instructions of the Vitodens 200-W, B2HA for details.
*7 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.
*8 Add approximately 2b inches (65 mm) for coaxial vent pipe transition adaptor.

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.

Waterside Flow (primary circuit)
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 t across the
system through the sensory communication between the
low-loss header and the boiler.

Before using the following pumps for a DHW tank
application, find out the proper pressure drop through the
tank, the required temperature difference through the coil
and system piping head loss of the domestic hot water.
Pump selection must be based on accurate system flow
and pressure drop calculations (incl. DHW sizing).

DHW Production
Domestic Hot Water Production
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.

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.

6. Connect the boiler to the installation fittings.
Vitodens 200-W B2HA 100 to 150 Technical Data
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.
CAUTION
The boiler must be level both vertically and horizontally
to ensure proper draining of the condensate.
