CAUTION!
Boiler shutdown due to excessive water pressure
During operation the pressure limiter switch
shuts down the boiler at a water pressure of
2.8 bar. From a water pressure of 3 bar the
safety valve drains the water.

When filling, exceed the required system pressure
by no more than 0.2 bar (for bleeding).
Bleeding the heating system
Open the ball valves on the heating circuits and bleed
the heating system completely. After bleeding, check
the water pressure and adjust if necessary.
Checking the water-tightness of the piping
Check the water-tightness of all piping. If there is any
water leakage, its cause must be found and
eliminated.
9.8 Attaching pellet hoses
Note instructions about laying pellet hoses
When laying the pellet hoses, take note of the
comments; see
11.7 "Information about pellet
hoses" .
Mounting fire protection sleeves (if required)
If the pellet hoses from the storeroom are routed
over a fire section (for example a room in-
between) to the boiler room, fire protection sleeves
must be fitted over both pellet hoses. In wall ducts, a
fire protection sleeve must be mounted on each side,
with ceiling ducts only positioned on the ceiling side.
Fig. 9-31: Fire protection sleeve
Use the supplied concrete screws to fasten the fire
protection sleeve. These screws are screwed directly
into the wall by pre-drilling, but without dowels.
In the event of a fire, the internal material of the fire
protection sleeve expands and thus closes the pellet
hoses. This prevents burn-back in rooms through
which the pellet hoses are fed.
CAUTION!
The copper wires must have good contact with the
connections for the pellet hoses.
Otherwise the hoses will not be earthed with the boiler
and there is a risk of electrostatic charge build-up.
 Remove the paint or the coating from both pellet
hose connections.
Attaching the pellet hoses to the boiler
On the ends of both pellet hoses, free around 10 cm of
the copper wire strands from the hoses.
Fig. 9-32: Exposing the copper wire
Push both pellet hoses onto the nozzles on the boiler
and fasten them with the hose clamps. Connect the
copper wires from both pellet hoses to the yellow-
green earthing cable (next to the nozzles).
