Install the condensate drain pipe with a suitable gradient.
Discharge condensate from the boiler into the drainage
system, either directly or (if required) via a neutralization
unit (accessory).
IMPORTANT
Pipe ventilation must take place between the siphon trap
and the neutralization unit (if applicable).
Condensate Connection/Neutralization Unit
Condensate Drainage and Neutralization
The condensate formed both in the condensing boiler and
in the flue gas pipe must be discharged into the public
sewage system in accordance with all applicable local
regulations. The condensate produced by a gas-fired
heating system has a pH value between 3 and 4.
Some local codes may require the use of a separate
neutralization unit to treat the aggressive and corrosive
nature of the condensate. With a neutralization unit
installed, all condensate from the boiler and the flue gas
pipe enters into the neutralization unit where it is treated
and released into the public sewage system with a safe
pH value of above 6.5.
The use of neutralization granulate (performing the
neutralizing process) is dependent on the operation of the
heating system. To determine the required refill amount,
check granulate level several times during the first year
of operation. In some cases one granulate fill may last an
entire year.
Contact Viessmann to order a neutralization unit for the
Vitodens 200-W boiler.
See Viessmann Price List for order information.
The condensate discharge outlet to the drainage system
connection must be clearly visible. It must be installed
with a suitable gradient and provided with a stench trap.
If the condensate outlet of the Vitodens 200-W boiler is
lower than the drain, a condensate pump must be used.
Only corrosion-resistant materials must be used for
condensate drainage purposes (e.g. braided hose). Do not
use galvanized materials or materials containing copper for
piping, couplings etc.
The condensate drain must have a trap to prevent flue gas
leakage.
Please note that other requirements might apply
depending on local regulations and/or project-specific
details.
It is advisable to contact your local waterworks office
(authority responsible for waste water regulations)
well before commencing with the installation of the
neutralization unit in order to establish details of local
regulations that apply.
