Caution!
Solid-fuel boilers must be
designed in accordance with
EN 12828 and feature a sa
-
fety heat exchanger with a
thermal safety valve.
Its response temperature is
95°C.
The heat exchanger must ne
-
ver be used to generate hot
water.
Note:
Before putting the system
into operation, check the safe
functioning of the thermal sa-
fety valve!
6.1 Connection of the supply and return
pipe
Connect the supply and return pipe to the hea-
ting system in accordance with the planned
system diagram. Carry out pipe dimensioning
according to the system calculation! All con-
nections are labelled, but are also visible from
the dimensions drawing.
6.2 Bleeding the system
Due to the large amount of water involved, the
fully installed system cannot be bled in a single
step.
The amount of water within the system con-
tains a large proportion of air bubbles, which
will gradually make their way to the highest
point of the safety heat exchanger.
For this reason, and based on experience, the
bleeding process should be carried out 3-4
times.
The bleeder hose included is simply placed on
the bleeder valve.
The back wall of the fireplace should therefore
only be fitted once all bleeding work has been
carried out
