Description
The Honeywell S8701A1098 is a Direct Spark Ignition (DSI) module engineered for reliable, safe burner ignition in gas-fired heating appliances. Designed for use in systems requiring a 2-rod configuration — one rod for spark ignition and one for flame sensing — this module delivers precise ignition sequencing with a 6-second trial for ignition period. If flame is not established within the trial period, the module locks out and activates an alarm output to alert technicians and building occupants of the fault condition, supporting rapid diagnosis and service response.
