Nti 85040 Spark Transformer Kit with Electrode and Mounting Bracket Tx51-151c

Product Description

The NTI 85040 Spark Transformer Kit is a factory replacement assembly designed for NTI Tx51-151C series boilers. This kit provides everything needed to restore reliable ignition performance on compatible NTI heating systems. It includes the spark transformer, spark electrode, and mounting bracket as a complete set, making it a direct replacement for technicians servicing NTI condensing boilers in residential and light commercial applications. The kit bundles component references 83707, 83724, and 53054 into a single part number, reducing parts sourcing time and ensuring all matched ignition components arrive together. HVAC service technicians and boiler specialists rely on manufacturer-supplied ignition kits like the NTI 85040 to avoid compatibility issues that can arise when mixing third-party ignition parts. The spark transformer in this kit steps up voltage to generate the high-energy spark needed to ignite the gas burner inside the boiler. Without a functioning transformer, the burner will not light, leaving the heating system inoperative. The spark electrode directs that electrical discharge precisely to the burner flame zone, while the mounting bracket positions the electrode at the correct gap and angle for consistent ignition. Replacing these components as a matched set helps ensure proper spark timing and gap alignment, which are critical for clean, reliable burner light-off. This kit is sold as one assembly per pack and is a stock replacement part supported by NTI Boilers, a manufacturer known for high-efficiency condensing boiler technology. Technicians working on NTI Tx series boilers experiencing ignition lockout, no-heat calls, or intermittent burner lighting issues should evaluate the spark transformer and electrode as part of standard ignition system diagnostics.
