Fuel(s)
Natural gas or liquid propane gas.

Boiler control

The Vitocrossal 200 boiler series is operated with
a Vitotronic control and microcomputer indoor/
outdoor control system for boiler operation without
low temperature limit. The control system must be
programmed for this type of operation by the installer.
Control instructions supplied with boiler control.

Condensate disposal

During the operation of the Vitocrossal 200 boiler,
the amount of condensate as per the diagram can be
expected.
The values given are approximate amounts occurring
under practical conditions. Not included in the chart is
the amount of condensate occurring in the vent pipe and
chimney system. The condensate from the chimney
system can be collected together with the condensate
from the heating boiler and be disposed of into a floor drain.
The condensate occurring will have a pH value between
3 and 4. If local building requirements demand neutralizing
the condensate before disposal, contact Viessmann
Manufacturing Company Inc. for a correctly sized
neutralization tank. The treated condensate will show pH
values of between 6.5 and 9 and can then be disposed of
into the waste water system.

Boiler location

The boiler must not be installed in rooms or areas where
halogenated hydrocarbons are present in the combustion
air, such as barber shops and beauty salons, printing
shops, chemical cleaners, laboratories etc.
CAUTION
The boiler room must be safe from frost and be
properly ventilated.

Venting connection

A large amount of water vapor contained in the flue gases
of condensing boilers condenses. The condensate pH
value is between 3 and 5.5. The flue gas temperatures
depending on the boiler water temperature may be
between 77° F (25° C) and 257° F (125° C).
The manufacturer of the chimney system or venting
system has to properly design the venting system as well
as select proper materials.
If there are any questions in regards to the neutralization
of the condensate and/or to the venting of this boiler
series, contact your local Viessmann Sales Representative.

Optimum operation

To ensure optimum operation of your heating system do
the following:
Keep the boiler and the boiler room clean and free

of dust and dirt.
Ensure proper and adequate system pressure by

occasionally checking the pressure gage.
Have a qualified heating contractor service and

maintain your heating system on a regular basis.
