Utica Boilers 43800013 Hot Surface Ignitor Replacement Kit 90% Condensing Boiler

Product Description

The Utica Boilers 43800013 is a replacement hot surface ignitor kit designed for use in Utica 90% condensing boilers. This kit provides everything needed to replace a failed or defective hot surface igniter and restore proper ignition function. Hot surface ignitors are a critical component in modern gas-fired boilers. When the thermostat sends a call for heat, the control board energizes the ignitor. The ignitor heats up to a very high temperature and ignites the gas at the burner. If the ignitor fails, the boiler will not light and no heat will be produced. Replacing a bad ignitor quickly is essential to restoring heat in residential and light commercial applications. The 43800013 kit includes one hot surface igniter, one igniter gasket, and installation instructions. This makes it a complete replacement solution for HVAC technicians and heating contractors working on Utica condensing boiler systems. One important note from the manufacturer: there are two different igniters used across the 90% condensing boiler product line. These igniters may look similar but have different insertion depths. Using the wrong igniter in a given boiler model can result in improper ignition or equipment damage. Always verify the correct igniter is being installed for the specific boiler model being serviced. Manufacturer documentation also confirms that part number 43800013 remains the correct replacement kit number across igniter design changes for the UB90-100 series, so technicians can order with confidence. This part is built for trade professionals who need a reliable, direct replacement to get systems back online fast. It is the OEM-specified replacement for Utica 90% condensing boiler ignition systems.
