Raypak 009057F - HSI Ignition Control Module

The Raypak 009057F is an OEM hot surface ignition (HSI) control module engineered for dependable burner sequencing and flame supervision in commercial boilers and volume water heaters. Operating on a 120V power supply, this solid-state controller governs the ignition sequence by accurately managing igniter warm-up, gas valve actuation, and flame rectification. Built for rigorous safety compliance, the control incorporates a 4-second trial for ignition (TFI) with a single-try lockout protocol to safeguard equipment from unburned fuel accumulation. As a genuine factory replacement, it ensures direct plug-and-play installation, restoring optimal operational safety and heating performance with minimal downtime.

• Precision Safety Timing: Features a 4-second trial for ignition (TFI) that rapidly verifies flame presence to maintain safe combustion chamber conditions.
• Single-Try Manual Reset: Automatically locks out the burner after one failed ignition attempt, requiring manual reset to ensure system inspection before re-firing.
• 120V HSI Compatibility: Designed specifically to control 120VAC hot surface igniters, providing consistent and reliable ignition across heavy-duty heating cycles.
• Direct OEM Replacement: Manufactured to exact Raypak engineering specifications for seamless electrical fit, dependable flame sensing, and long-term durability.
