What to do if unit stops operating
If you discover damage to the heat producing component (boiler), the expansion tank, or the safety equipment,
you must discontinue operating the system.
Check the power supply (fuses) or the switchgear panel fuses
Boiler controller correctly set (everything on "AUTO")
Check the safety temperature limiter (See page 7)
The boiler temperature can't be throttled:
Too much material (See page 22)
Chimney draught too high (> 0.3 mbar) - Install draught controller!
Door seal not sound (boiler is burning with too much dead air)
Boiler output is too low:
Boiler is probably dirty - See pages 10 - 13 "Maintenance and Cleaning"
(See page 4 "fuels") - Solution: use a better quality of fuel
Over-heating:
If the boiler system should over-heat in spite of all the safety systems, take the following
precautions:
- Keep all doors and covers closed on the boiler
- Switch on all the pumps and open the stirrer
- Leave the boiler room
- Inform customer service
If fault messages appear on the boiler controller display, see the error message list!
For faults that occur on a frequent basis (safety temperature limiter has fallen) or for faults that can't be
cleared by the operator, notify the installer, heating technician, or our customer service.
