CONDENSATE DRAIN
The boiler produces a significant amount of
condensate during operation. This condensation
has an acidic pH of 3-5. Follow all local codes and
regulations when disposing of condensate from
the boiler.
The project engineer should consider the
possibility of installing systems to eliminate the
acidic condensation, according to system power
and buildings’ use.
The system should be designed to avoid
the condensate freezing. Before the boiler
commissioning, check the correct condensate
flow.
WARNING
Check before connecting the condensate
trap to the drain pipe, for the proper
gradient of boiler as described in paragraph “1.1.8
POSITIONING AND MINIMAL TECHNICAL SPACES”.
WARNING
Properly connect the siphon condensate
from the boiler to a drain system having adequate
slope. Where possible, you should make this
connection using transparent tubing to check for
proper condensate drainage and avoid stagnation that
could cause hazardous backflow of the condensate
into the boiler.
To connect the condensate drain use only
corrosion-resistant material for the drain line.
CONDENSATE NEUTRALIZER KIT
The condensate neutralization system neutralizes
the condensate created by the products of
combustion.
Acid condensate, introduced into the neutralization
box, follows a two-step set course. First phase:
nitrates and sulphates filtration through active
carbons contained in the first part of the carbon
site pipe. In the second phase the pH rises.
The acidity of the condensate can be controlled
through the use of appropriate tools for the
determination of Ph, such as the litmus paper.
Neutralized condensate can then be routed to the
drainage system.
MAINTENANCE
The pH value of the condensate after the neutralizer
must be in between
<5,5 – 9,5>
.
Every six months, you need to determine the pH of
the condensate treated in the neutralizer. Litmus
paper or a digital instrument can be used to
measure the pH level.
Neutral point is on the 6,8-7 value; in case of lower
value the condensate is acid, in case of a higher
value it is basic.
If necesssary, replace the active carbon and the
reagent granulate.
