Start-up/shutdown
Heat-up preparations
Fig. 4
1. Check the pressure of the heating system at pres-
sure gauge
:
A
The system pressure is too low if the indicator
points to the area below the red field. Top up with
water or notify your local heating contractor.
Minimum system pressure: 1.0 bar (0.1 MPa)
Ideal log dimensions
Fig. 5
■
Split log length 45 to 50 cm.
■
Shorter logs must be layered without air gaps in the
boiler hopper.
■
25 cm long logs can be inserted crosswise next to
one another.

2. Check that the vent in the installation room is unre-
stricted.
Note
The combustion air is drawn from the installation
room during operation.
3. Check that the heating system or the heating water
buffer cylinder can draw off heat. Where neces-
sary, open the thermostatic valves.
4. Check that the heating system has been vented.
5. Ensure that all shut-off gate valves to the heating
flow and return are open.
6. Check that all doors and covers on the boiler are
closed.
7. Ensure that all ball valves for the return tempera-
ture raising facility are open.
8. Ensure that power is supplied to the boiler.
Note
Differing log dimensions can only be layered with
gaps. Gaps reduce the boiler output and increase the
risk of ineffective gasification.
