Thermal discharge safety device trips constantly (constant water out-
flow through the discharge). The water heat exchanger cannot dissipate
heat to the heating system.
• The buffer tank is "full" Remove heat from the tank.
• Check function and settings of the pump thermostat and the return flow
boost.
• Set the pump one level higher (higher flow rate).
• Circulation pump does not run. Power connection defective?
• Venting the the stove:
• Check system pressure.
During first usages, water escapes in the field of garden soil.
If the stove and the heating systems was tested under pressure after installation,
the water discharged is condensate from the fuel and the combustion chamber
liner. If more than 0.2 litres of water accumulate, then the heating system pres-
sure must be tested.
Gurgling noises in the water heat exchanger.
• Air in the system, check the system pressure.
• Ventilate system via the vent. For newly filled or topped up systems it takes
some time for all the air to collect. Often ventilating once does not suffice.
Thermal discharge safety device drips.
• Flush the thermal discharge safety device by activating the red button on
the fitting.
• Check the seat of the connection seals and the piston (see the manual
thermal discharge safety device).
• If necessary, integrate filter in the system upstream of the discharge safety
device (pay attention to the minimum flow rate!)
Radiators do not warm up. Radiators that are not located in the instal-
lation room are cold.
• Close radiator thermostats when the set room temperature is reached. The
convection heat of the fireplace is distributed in the air composite.
• Depending on the configuration the heating system is sluggish. It takes some
time until the heating system dissipates its heat.
• Have the heating system hydraulically calibrated.
• Check that the heating circulation pump is functioning.
• Increase the amount of fuel.
Increasing and faster contamination of the combustion chamber lining
and of the glass ceramics. The combustion chamber lining no longer
burns free. Fire can only be ignited with difficulty
• Remove deposits in the heat exchanger and in the connecting line to the
chimney. Remove deposits in the heat exchanger and in the connecting line
to the chimney.
• Check that the pump thermostat is functioning properly.
• Pay attention to correct firing, wood feed quantity, wood moisture content
< 20%.
• Correct the position of the air control lever.
• Check that the return riser is functioning properly.
Fast contamination of exhaust gas flue in the water heat exchanger.
Inadequate fire behaviour.
• Check the return riser.
• Pay attention to correct firing, wood feed quantity, wood moisture content
< 20%.
• Remove deposits in the heat exchanger and in the connecting line to the
chimney.Remove deposits in the heat exchanger and in the connecting line
to the chimney.
• Check that the pump thermostat is functioning properly.
