Entering the storeroom BS-02-04-00-14-01-BAEN
Filling the storeroom BS-02-04-00-15-01-BAEN
Danger: Risk of detonation.
A flue draught regulator with a pressure surge
compensator is an essential requirement.
Danger: Fire risk.
Do not store any flammable items in the close
vicinity of the boiler.
Follow the local regulations.
Danger: Potentially fatal health risk!
As with all organic materials, stored pellets
can produce gases, which then collect in the
storeroom. Therefore, entering the storeroom
is only allowed when it is empty (max. 1/5 full)
and only after ventilating it thoroughly for at
least 2 hours beforehand.
Storerooms that contain more than the above
amount of fuel may only be entered by
authorised service engineers after prior
testing of the air quality inside the storeroom.
Danger: Risk of injury!
Only enter the store room when the
system is switched off. Always shut off
the power supply before entering.
Affix a sign to the storeroom door.
Keep the storeroom doors locked.
Danger: Risk of poisoning and fire!
When filling the fuel storeroom from a tanker
truck or using a pressure-filling system, it is
imperative that the boiler is shut down (OFF
mode).
If this rule is ignored, flammable and
poisonous gases can be drawn into the
storeroom.

4 Safety systems BS-04-00-00-00-01-BAEN
To prevent the boiler overheating, the controller reduces the
heat output in certain situations. If the boiler still threatens to
overheat, the controller responds according to a set of defined
safety levels.
Safety level 1 BS-04-00-00-01-01-BAEN
15°C above specified temperature
The drive motor stops the fuel feed system and the flue
draught fan shuts down.
Safety level 2 PH-04-00-00-01-01-BAEN
Boiler temperature above 90°C
All heating pumps and the cylinder charging pump are
switched on to carry heat away from the boiler.
Safety level 3 BS-04-00-00-01-03-BAEN
Boiler temperature above 100°C
The STL (safety temperature limiter) trips and switches all
boiler control functions off while the heating circulation pumps
continue to run. The system remains switched off even if the
boiler temperature drops back below 90 °C. The system must
not be started up again until any faults have been rectified and
the boiler has been checked.
Power failure BS-04-00-00-04-01-BAEN
The controller, the flue draught fan and all circulation pumps
switch off due to lack of electricity if there is a power cut. The
glowing fuel bed on the grate continues burn with the natural
draught of the flue. As this operating mode is not ideal, a
larger amount of ash collects on the grate as well. As soon as
the electricity supply is restored, the controller takes control of
the heating system again.
Opening ash box or firebox door PH-04-00-00-02-01-BAEN
The drive motors stop feeding the boiler with fuel
The flue draught fan switches to maximum extraction speed
After the ash box/firebox door is closed, normal operation is
resumed
