Description
The Honeywell S8701A1034 is a Direct Spark Ignition (DSI) module engineered for dependable, automatic ignition control in gas-fired heating appliances. With an 11-second ignition trial period and a 30-second prepurge cycle, this module ensures safe burner startup by purging residual gas from the combustion chamber before ignition is attempted — reducing the risk of unburned gas accumulation and unsafe lighting conditions.
Designed as a direct replacement for compatible Honeywell DSI systems, the S8701A1034 delivers consistent spark ignition performance in furnaces, unit heaters, and other gas-fired equipment. Its proven lockout and retry logic helps protect equipment and occupants by shutting down the system if ignition is not established within the trial period.
