Fenwal 35-615900-227 Module Refrigerant and R-22 systems requiring aThe Fenwal 35 615900 227 is a microprocessor based 24V Direct Spark Ignition (DSI) module specifically engineered as a direct Armstrong furnace replacement. Designed for gas fired appliances, this ignition control module manages the inducer blower relay, flame sensing, and gas valve synchronization with high precision timing. High level performance is sustained through its 30 second pre purge and 15 second trial for ignition (TFI) cycles, which ensure
