It carries alternate part number 6008387001 and is a direct OEM replacement part. This electrode assembly uses a dual-probe design to deliver a consistent, strong spark for fast and reliable flame establishment every time the boiler fires. Reliable ignition is critical in condensing boiler systems, where a failed or weak spark can cause lockout conditions, delayed ignition, or incomplete combustion. The NTI 83870 eliminates those risks by providing dependable electrode performance that HVAC technicians and boiler service professionals can count on during installs and service calls. The electrode gap is set between 3 inches to 1 inch 4 inches on the spark gap, matching OEM specifications for proper spark intensity and combustion timing. The insulator body is made from high-temperature ceramic, which withstands the extreme heat inside the combustion chamber without cracking or degrading. This ceramic construction also prevents current leakage, ensuring the spark jumps consistently across the correct gap. The kit includes the NTI 82774 graphite gasket, which provides a proper combustion-chamber seal when the electrode assembly is installed. Including the gasket eliminates the need for a separate parts order and ensures the job is done right with a matched OEM component. This part is the correct replacement for technicians servicing NTI condensing boilers and is also listed under alternate part number 83870-1. HVAC professionals performing boiler tune-ups, ignition system repairs, or boiler start-up commissioning will find this assembly straightforward to install with factory-correct fit and function.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDual-probe spark ignitor design for strong, consistent flame establishment in NTI condensing boilers\u003c\/li\u003e\n\u003cli\u003eHigh-temperature ceramic insulator resists heat and prevents current leakage for reliable spark performance\u003c\/li\u003e\n\u003cli\u003eIncludes NTI 82774 graphite gasket for a complete, properly sealed combustion-chamber installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe NTI 83870 dual spark ignitor is an OEM ignition electrode assembly designed for direct replacement in NTI condensing boilers.
