Part 6 - Condensate Drain
This appliance produces liquid condensate in the heat exchanger and venting system as a product of combustion.
Provisions must be taken to ensure that condensate does not collect in the venting system; therefore, all exhaust
piping must slope back to the appliance a minimum of 5 cm per mtr (0.60 inch / feet). Condensate must be
drained from the appliance into a household drain.
Notice
Check with your municipality, or local gas company to determine if the disposal of combustion condensate
is permitted in your area.
The following are important notes that must be taken into consideration when constructing the condensate
drain system (See figure 6.1 for further details):
DO NOT
install condensate lines outside. A frozen or blocked drain will cause the condensate to fill
the
combustion chamber.
NEVER
use copper, steel, or galvanized piping in the construction of the condensate system
(condensate
is very corrosive and will corrode most metals). Use synthetic material only.
Warning
If the combustion chamber has been flooded due to the condensate drain backing up, or for any other reason,
the combustion chamber door must be removed and the inside of the appliance must be inspected for
component damage by a certified technician, e.g. the internal insulation at the front and back of the chamber.
Failure to follow these instructions may result in fire, property damage, serious injury or death
.
The condensate collector is situated at the left lower side of the boiler. The collector has been equipped with
a single condensate hose. The supplied dirt filter / water lock must be assembled to the condensate hose.
The collector is mounted into the boiler by a turning movement.

Figure 6.1 Condensate collector and hose location
Connect the condensate collector with a flexible hose to the sewer. Use an open connection. Make sure that the
condensate collector will be accessible for maintenance. Take care of a minimum space below of minimal 270
mm (11”). All piping must be below the level where the condensate leaves the boiler.
Warning
Blocking the condensate drain can cause damage to the boiler. The boiler has been constructed in such a way
that in the situation of a blocked siphon / air trap the boiler will shut down.
Notice
Check with your local authorities regarding disposal of condensate (regulations may require the use of
a neutralizer).
