3.4 Connection condensate pipe
The gas-fired condensing air heater must be fitted with a siphon to drain the condensate water. The
supplied siphon must be fitted during installation. Note that the discharge of the condensate must be
carried out with material which is resistant to acid water with a pH of 3. Never use copper or galvanized
iron pipes. For the disposal of condensed water you must use PVC pipes with a diameter that is equal to
this of the unit (PVC
Ø
32). Make sure the piping is placed on sufficient slope. Check the tightness of the
plumbing of the condensate. Before using the unit, fill the siphon with water through the filler cap. This
avoids that combustion gas will get into the sewer during the start-up.
Anti-freeze protection
The condensate drain, including the siphon, must be protected against frost. It is preferred to keep the
drains frost-free as best as possible. In case they fall outside the building, the pipe part behind the siphon
should be open to avoid the formation of ice which will block the discharge. Take the necessary precautions
to avoid such an incident, as this may cause irreversible damage to the heater.
Neutralization of the condensate
The acidity of the condensate from the combustion of natural gas is 3,5-3,8 pH. In certain regions it is
required that the condensate must be treated before it can be discharged. In these cases you should take
on a neutralization kit in the condensate circuit.
