Siemens Combustion LFL1.335-110V Control
The Siemens Combustion LFL1.335-110V Control is a specialized 120V gas burner control engineered for the management and supervision of forced draft burners and atmospheric burners of medium to high capacity. This electro-mechanical primary flame safeguard is essential for multistage or modulating burners in intermittent operation, requiring a controlled shutdown every 24 hours. Professionals rely on the LFL1.335 for its ability to provide precise burner sequencing, automatic ignition, and continuous flame monitoring using UV detectors (QRA series) or ionization probes.
The unit features a fixed program sequence including pre-purge (t1) of 37 seconds and a safety time (TSA) of 2.5 seconds at 60Hz. It integrates a flame amplifier and provides checked air damper control to ensure the actuator reaches the required high-fire or low-fire positions before proceedings. Housed in a heat-resistant black plastic, it includes a lockout indicator light and a manual reset button for efficient troubleshooting during field maintenance.
Key Benefits:- Universal Compatibility: Designed for gas, oil, or dual-fuel single burner applications.
- Operational Precision: Provides proven air switch function and high-fire/low-fire purge interlocks for safety compliance.
- Comprehensive Monitoring: Continuous flame supervision including extraneous light detection to prevent false signals.
- Contractor-Friendly Design: Includes symbolic visual sequence indication and an integrated fuse with a spare provided in the housing.
- How do I resolve a lockout indicated by the orange light? A lockout typically occurs due to flame detection failure or air pressure issues. Verify the UV sensor or ionization probe is clean and check the air pressure switch (LP) settings.
- Are the switching times the same for 50Hz and 60Hz? No, at 60Hz, the sequence times are approximately 17% shorter than the 50Hz values listed in standard Siemens LFL1.335 documentation.
- Can this unit be used for continuous operation? No, the LFL1.335-110V is strictly for intermittent operation. For continuous duty applications, you must use the LGK16 series.
