Honeywell SV9520H8513 is a 1/2" x 1/2" NPT Direct Hot Surface Ignition SmartValve Control with fast-slow opening and 3.5" wc pressure regulator setting.

The unique design of new SV9520 SmartValve System Controls combines gas flow control and electronic direct main burner ignition sequencing functions into a single unit. The ignition source is 120V hot surface igniter lighting the main burner flame. The SV9520 features all gas ignition safety functions by controlling gas flow, ignition source, and a 120 Vac combustion air blower. It also monitors the appliance airflow proving switch circuit and limit string to assure proper appliance operation. The SmartValve System Controls provide prepurge, postpurge and timed trial for ignition with multiple ignition trials and auto reset from lockout. Its diagnostic LED indicates the system status.


  • The control communicates directly with the ST9160 Electronic Fan Timer (EFT) in typical forced warm air furnace applications;
  • It will also interface with the 208907 Terminal Board, providing compatibility with power-stealing thermostats. Or, it directly interfaces with the appropriate power supplies and a system thermostat for additional appliance applications;
  • When controlled directly by a thermostat, the control does not provide a postpurge function, as power to the control is removed when the thermostat call for heat ends;
  • This system is suitable for a wide range of fan-assisted combustion, gas-fired appliances including furnaces, rooftop furnaces, boilers, unit heaters, infrared heaters, water heaters and commercial cooking appliances;
