Resideo SV9520M2536 24V Direct Hot Surface Ignition SmartValve Gas Control 1/2" NPT

The Resideo SV9520M2536 SmartValve is an integrated gas control system that combines gas flow regulation and electronic direct burner ignition sequencing into a single, compact unit. Designed for fan-assisted combustion applications, this control uses a 120V hot surface igniter (HSI) to reliably light the main burner flame with a 7-second warm-up period.

This SmartValve control provides comprehensive gas ignition safety by managing gas flow, ignition source, and a 120 VAC combustion air blower. The integrated system monitors the appliance airflow proving switch circuit and limit string to ensure proper operation. It features prepurge, postpurge, and timed trial for ignition with multiple ignition trials and automatic reset from lockout conditions.

Key Features:

• 1/2" NPT inlet x 1/2" NPT outlet connections for straightforward installation
• Factory-set 3.5" WC pressure regulator for precise gas regulation
• Standard opening design ensures smooth, consistent gas flow
• 24 VAC control voltage (60 Hz) with 40VA minimum transformer requirement
• Direct hot surface ignition with 7-second HSI warm-up time
• Diagnostic LED status indicator for simplified troubleshooting
• Universal mounting capability: 0 to 90 degrees in any direction
• Wide ambient temperature range: -40°F to +175°F
• Maximum capacity: 150 ft³/hr at 1" pressure differential
• Includes LP gas conversion kit for fuel flexibility

The SV9520M2536 communicates directly with the ST9160 Electronic Fan Timer (EFT) in forced warm air furnace applications and interfaces with the 208907 Terminal Board for compatibility with power-stealing thermostats. Suitable for a wide range of gas-fired appliances including furnaces, rooftop units, boilers, unit heaters, infrared heaters, water heaters, and commercial cooking equipment. Compact dimensions of 3.2" W x 4.9" H x 4.1" L allow for flexible installation in tight spaces. CSA certified for safety and compliance.
