Fenwal 35-605912-553 Module

The Fenwal 35-605912-553 is a 24V Direct Spark Ignition (DSI) control module specifically engineered for high-demand gas-fired systems. Known as the Triton Module (PMI Special), this unit utilizes advanced microprocessor technology to manage the ignition sequence, providing precise timing for purge and inter-purge cycles. For contractors troubleshooting in the field, the integrated DETECT-A-FLAME® flame sensing technology and diagnostic LED allow for rapid identification of system faults. This module is built to withstand extreme environments, maintaining operational integrity in temperatures ranging from -40°F to +176°F. Whether you are servicing commercial boilers, unit heaters, or infrared heating systems, the 35-605912-553 provides the technical versatility required for natural gas, propane, or manufactured gas applications.

Common Technical Questions

Is the Fenwal 35-605912-553 compatible with propane systems?
Yes, this ignition control is rated for use with natural gas, LP (propane), and manufactured gas sources.

How do I check the strength of the flame signal?
Technicians can measure the signal directly at the flame current test points using a standard microammeter to ensure the sensor is meeting the minimum required signal strength.

Can this replace a multi-trial ignition module?
This specific PMI Special module is designed for 24VAC input and supports single or three trials for ignition depending on the internal configuration; always verify the pre-purge and trial-for-ignition (TFI) timings of the original part before replacement.
