Vitocrossal 300, CT3 Series Operating
CAUTION
The boiler room must be safe from frost and be
properly ventilated.
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.
Vitocrossal 300 boiler efficiency dependent on system
heating water return temperatures and load conditions
During the operation of the Vitocrossal 300 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 between 3 and 4
on the pH scale. 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.
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.
