Lennox 70N68 Pilot Burner
The Lennox 70N68 Pilot Burner is a critical OEM replacement component designed specifically for natural gas applications in high-efficiency heating systems. As a veteran technician knows, a reliable pilot flame is the foundation of safe burner sequencing. This assembly is engineered for use in Lennox 3-9 section gas-fired boilers and GSB8 series water boilers, ensuring consistent ignition and preventing the nuisance lockouts or "no-heat" calls often caused by carbon-fouled or degraded pilot orifices. The 70N68 pilot assembly features a precision-drilled orifice to maintain a stable, "blowtorch" style flame even under varying manifold pressures, facilitating rapid main burner light-off and optimal thermal transfer.
When troubleshooting a Lennox furnace not igniting, the pilot burner is often the primary failure point due to oxidation or thermal stress. This HVAC replacement part restores the system to its original factory specifications without the need for field modifications. Its compact footprint—approximately 1 inch in length and width—allows for straightforward installation in tight burner vestibules. For contractors maintaining older gas-fired furnaces or boilers, carrying a high-quality natural gas pilot burner is essential for resolving ignition flame failures and ensuring long-term operational reliability.
Key Benefits
- OEM Precision: Guaranteed Lennox boiler parts compatibility for 3-9 section and GSB8 series units.
- Natural Gas Optimized: Engineered specifically for Natural Gas Pilot Burner performance to ensure clean combustion.
- Enhanced Ignition Security: Prevents furnace lockout by providing a stable flame for thermocouple or flame sensor verification.
- Rugged Construction: Built to withstand the high-temperature environment of the combustion chamber.
Common Questions
- Why is my Lennox pilot flame yellow or lifting? A lazy yellow flame typically indicates a dirty orifice or incorrect gas pressure; the 70N68 restores the sharp blue flame required for proper ignition.
- Will this work for a propane (LP) conversion? No, this specific part is designed for pilot burner nat gas applications only; using it with LP requires a different orifice size.
- How do I know if the pilot burner or the thermocouple is bad? If the pilot lights but won't stay lit after releasing the valve, the thermocouple is likely at fault. If the pilot won't light at all or the flame is too small to reach the sensor, the Lennox 70N68 should be replaced.
