Raypak 004818B Ignition Control

The Raypak 004818B Ignition Control is a critical OEM replacement component designed for intermittent pilot ignition (IID) systems in residential and commercial pool heaters. Engineered for precision and safety, this electronic ignition module features a 100% lockout safety mechanism that terminates gas flow to both the pilot and main burner if a flame is not detected within the designated trial-for-ignition period. This 24V ignition control is a direct replacement for older Honeywell S8600 and S86 series modules, ensuring seamless integration with existing 24VAC gas valves and transformer configurations.

For service technicians, the Raypak 004818B provides high-reliability flame rectification sensing, which is essential for preventing hazardous gas accumulation. The kit includes the necessary spade connectors and hardware to adapt from legacy round connectors on high-tension wires to modern 1/4-inch terminals. This module is standard on Raypak Versa models including the 055A, 105A, 155A, and 185A series, and is optimized for LP propane applications while maintaining broad compatibility across the digital heater lineup.

Key Benefits

• Enhanced System Safety: The 100% lockout feature prevents continuous gas discharge during ignition failure, protecting the combustion chamber and surroundings.
• Universal Compatibility: Serves as a versatile replacement for Honeywell ignition modules in Raypak Digital and Gemini/Spa-Pak heaters.
• Reliable Cold Starts: Advanced intermittent pilot logic provides consistent spark energy for reliable ignition in diverse outdoor environments.
• Simplified Installation: Comes complete with mounting screws and a 1/4-inch spade connector for quick field adaptation.
• OEM Performance: Ensures exact electrical matching with Raypak heater parts, maintaining the original engineering specifications for 24-volt operation.

Common Questions

How do I troubleshoot a lockout condition on the 004818B?
If the module enters lockout, verify that the pilot burner is clean and correctly positioned. Use a multimeter to ensure 24VAC is present at the PV terminal. If the pilot lights but the main burner fails to fire, check for a steady flame sense signal (minimum 5 microamps) through the sensor electrode.

Can this module replace a non-lockout Honeywell S8600?
Yes, the Raypak 004818B is designed to replace older analog and non-lockout units. Upgrading to a lockout-style module is often recommended by contractors to improve the safety profile of older pool heating equipment.

Is the high-tension spark wire included in the kit?
The kit includes the ignition module and adapting connectors. If your existing spark ignition wire is brittle or damaged, it should be replaced separately to ensure proper voltage delivery without grounding out to the heater chassis.
