• Check if the combustion fan is running.
• Check if the flue system is blocked or restricted.
• Check the pressure switch and the connections.
• Check the heat exchanger for flue leakage.
Case 12: E-error for more than 24 hours.
• Switch the air heater off and on and check the error
code.
Case 13: Internal error.
• Isolate the electrical supply and reenergise. If this
does not help:
–
Replace the burner control unit.
Case 14: Pressure switch is closed in stand-by mode.
• Check if the contact is stuck. If so:
–
Replace the pressure switch.
• Check if there is water in the hose. If so:
–
Dry the hose.
Case 15: Flame detected after closing the gas valve.
• Check if the gas valve closes too slow. If so:
–
Replace the gas valve.
• Check if the ionisation electrode is wet. If so:
–
Dry, clean or replace the electrode.
Case 16: Flame detected before opening the gas valve.
• Check if there really is a flame before ignition. If so:
–
Replace the gas valve.
• Check if the ionisation electrode is wet. If so:
–
Dry, clean or replace the electrode.
Case 19: Heater configuration error
• The heater does not know which program to run,
due to a mismatch between the burner control unit
and the display. If so:
–
Contact your supplier.
9.5 Further troubleshooting
When the air heater does start but shows a different
problem than described above, check if the following
problems apply.
9.5.1 Explosive ignition and/or frequent flame failures
• Check if the gas control settings are correct (see
§8.1). A correct CO
2
value is important for a proper
ignition.
• Check the ignition cable. It should have a
resistance of 1 kΩ.
• Check the position of the ignition electrode.
The spark has to be formed between the two
electrodes, not between the electrode and the
burner.
10 Maintenance
CAUTION! The air heater must be inspected and
cleaned once a year by a qualified installer with sufficient
knowledge about the device.
CAUTION! Sufficient maintenance is critical in
circumstances such as high humidity, dust, high switching
on/off frequency, etc.
10.1 Preparation
Before performing maintenance on an air heater that is
already installed, do the following:
1. Set the thermostat to the lowest setting.
2. Close the manual gas valve.
3. Turn off the power supply to the air heater using the
maintenance switch.
CAUTION! Always check for gas leaks after working on
the air heater.
CAUTION! Do not use water when cleaning the air heater.
CAUTION! The heater must be electrically isolated during
servicing.
10.2 Basic maintenance
To perform basic maintenance on the air heater, do the
following:
CAUTION! When cleaning parts of the air heater, use
a dry cloth, brush, compressed air or a vacuum cleaner.
Never use a steel brush.
