Fuel Conversion Label Kit (NG>LPG)
(included in boiler technical literature set)
The Vitodens 200-W, B2HA boiler comes factory set
for operation with natural gas. All B2HA models can be
field converted to operate with liquid propane gas (as
well as back to natural gas as required). The kit includes
instructions and labels for field conversion.
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.
