Operation
Combustion air blower is turned on and process limits are controlled by external circuitry (see wiring). At power on the device per forms a selftest and displays messages if system failures are
detected. Once the equipment has been successfully tested, the device waits for manual startup (standby mode) or starts prepurge time (autostart mode) depending on the selected configuration.
A ame detection or simulation during prepurge time leads to lockout condition. If a stable flame has been detected the burner is regularly ignited. If the burner does not ignite within the safety
time the system locks out.
Flame quenching will lock the system and it can (depending on the selected confi guration)
