Smith 100110701 - Flame Rod","description":"\u003cp\u003eMaintaining accurate burner flame detection is critical for the continuous operation of your hydronic system. The Lochinvar \u003cstrong\u003e100110701\u003c\/strong\u003e flame rod serves as the primary sensor responsible for verifying ignition, ensuring your boiler cycles correctly and prevents fuel waste. By providing a clean signal to the ignition control module, this \u003cstrong\u003e100110701\u003c\/strong\u003e replacement helps maintain consistent heat output and system reliability.\u003c\/p\u003e\u003cp\u003eThis device functions through flame rectification, where the rod is inserted into the flame path to create a small electrical current. As the flame burns, it acts as a conductor to close the circuit, signaling the control board that it is safe to maintain the gas valve in the open position. If the flame rod fails to detect this ionization, the system will initiate a safety lockout to prevent hazardous unburned gas accumulation.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame Rectification:\u003c\/strong\u003e Converts AC signal to DC for accurate combustion verification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Integrity:\u003c\/strong\u003e Provides clear conductivity between the flame and the control board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Temperature Durability:\u003c\/strong\u003e Engineered to withstand extreme combustion chamber environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Designed specifically for use with compatible Lochinvar and A.O.
