Rheem-Ruud 62-22578-01 HSI Module 34Sec Pre-Purge 8Sec Trial For Ignition 120/24V

The Rheem-Ruud 62-22578-01 HSI (Hot Surface Ignition) Module is an essential part of the gas-fired HVAC systems particularly furnaces for managing the ignition sequence. This module provides assured and reliable ignition on three attempts of ignition with a heating time of 34 seconds. This HSI module operates in a manner that it is able to regulate the sequence of operations required to ignite the furnace gas. It also controls the pre-purge time, heat-up time and ignition trial time to ensure a secure and efficient ignition procedure. It reduces risks, minimizes the possibility of gas accumulation and ensures that ignition is always perfect by allowing precise control of the ignition sequence. The device which is mostly used in gas furnaces assists in maintaining a constant and smooth ignition.
