Connection to the Condensate Drain
AKY boilers are condensing systems and, therefore, they are
equipped with a connection for pipe Ø18 for condensate drain.
Precautions
Condensation water outflow takes place at temperatures lower
than or equal to 50°C. For condensate drain, use pipes made
of PVC and/or all the materials suitable for use with hot pipes:
stainless steel, silicone pipes, etc.
Do not use galvanised iron or copper pipes.
Neutralising the condensation
The condensation produced by the combustion of natural gas
has an acid pH of 3.5-3.8.
On request, Apen Group can supply the kit (G14303) required
to neutralise the condensation; the kit consists of:
•
Plastic tank for the collection of condensation;
•
Calcium carbonate.
For more information, contact Apen Group Service centre.
Protection from frost
In case of outdoor installations in very cold places, with the
risk of condensation freezing, we recommend to protect the
condensation drain system.
We recommend that the condensation collection system is
located inside heated rooms.
If the system is located outdoors, the pipe must have an open
type connection to make sure that any ice formed inside the
external system does not prevent the condensation from being
drained away.
In any case, it is recommend that the longest pipe should be
laid inside the heated room, for example by collecting the
condensation flush to the floor with the down pipe located
inside the room.
Exhaust with Sealed fume trap
The trap, code C09385, prevents the flue gases from coming
out also when there is no water.
The trap is equipped with a detection electrode.
•
To connect the trap to the condensation drain system, use
PVC or silicone pipes.
•
The pipe must never exceed the height of the lowest trap.
•
Condensation collection pipe water tightness must be
guaranteed.
5.8. Hydraulic circuit filling
Boiler models differ from each other in that AKY032/034 models have
already been refilled with water-glycol mix and are equipped with
two cut-off taps on the hydraulic circuit, whereas AKY050/070/100
models have not been refilled (check the expansion reservoir
capacity according to the water quantity in the system).
The type of glycol required is the same for all models.
Upon delivery, AKY032/034 boilers have already been refilled
with a suitable amount of 30% water-glycol mix, sufficient for
proper hydraulic circuit filling of the following components:
boiler, AB018/032/034 internal unit and flexible hoses up to 1
metre supplied with the equipment.
Filling or water replenishment operations are the same for
all models.
