Hydrotherm 04-1346 Flame Sensor
The Hydrotherm 04-1346 Flame Sensor is a critical safety component designed for precise flame rectification in industrial and commercial boiler systems. As a veteran technician, you know that a reliable signal to the ignition control board is what prevents hazardous raw gas buildup and costly short cycling. This OEM-quality flame rod features a high-grade porcelain insulator and a durable metal element engineered to withstand the intense thermal stress of continuous combustion monitoring. Whether you are performing a seasonal tune-up or troubleshooting a no-flame lockout, the 04-1346 ensures the burner assembly communicates accurately with the system's safety logic. Its high sensitivity allows for the detection of microamp signals even in demanding gas-fired applications, maintaining optimal efficiency and reducing HVAC downtime. When a sensor becomes fouled by carbon deposits or oxidation, replacing it with this genuine Hydrotherm replacement part is the most effective way to restore non-stop operation and consistent heat output.
Key Benefits- Precise Flame Detection: Engineered for accurate flame sense signals, preventing nuisance shutdowns and 3-trial lockouts.
- OEM Durability: Built with premium materials to resist the corrosive effects of acidic combustion gases and high-heat environments.
- Safety Compliance: Vital for combustion safety, ensuring the gas valve remains closed if a stable pilot or burner flame is not present.
- Universal Hydrotherm Fit: Designed for seamless integration into various Hydrotherm boilers and gas-fired heating equipment.
How do I know if my Hydrotherm flame sensor is failing? The most common symptom is the boiler igniting for a few seconds and then immediately shutting down. If your control board shows a "no flame detected" error code despite a visible flame, the sensor usually requires cleaning or replacement.
Can I just clean the 04-1346 instead of replacing it? While cleaning with a fine abrasive may temporarily restore the microamp signal, it often removes the protective coating on the metal rod. For long-term reliability and to avoid emergency service calls, a full replacement is recommended once the porcelain insulation shows signs of cracking or heavy oxidation.
What causes rapid soot buildup on the sensor? Excessive carbon usually points to improper gas pressure or inadequate combustion air. If you are replacing sensors frequently, check the burner alignment and ensure the venting system is not obstructed.
