*5 Measured flue gas temperature with a combustion air temperature of 68° F (20° C).
*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.

Waterside Flow
Waterside Flow (primary circuit)
Vitodens 200-W, B2HA 19 to 80 Technical Data
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.
Supply head pressure (water)
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 rt across the
system through the sensory communication between the
low-loss header and the boiler.

Vitodens 200-W, B2HA 19 to 80 Technical Data
Heating Circuit / Boiler Pumps
Pump Information
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.

Boiler pressure drop
ft. (m)
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.
IMPORTANT
Pump selection must be based on accurate system flow
and pressure drop calculations (includes DHW sizing).
