Raypak 600525B Pilot Assembly

The Raypak 600525B Pilot Assembly is a high-performance natural gas standing pilot engineered specifically for millivolt pool heaters and residential boilers. This genuine OEM Raypak replacement part includes a integrated thermopile generator, ensuring consistent millivolt output for reliable gas valve actuation without the need for external electrical power. Designed for field service efficiency, the assembly features a 34-1/8 inch lead length and a 1-1/2 inch thermopile element, providing the precise spatial tolerances required for optimal ignition flame stability. It serves as a direct drop-in for Raypak RP2100, Gemini, Spa-Pak, and Digital Atmospheric models, effectively resolving common pilot burner failure codes and erratic startup cycles. For contractors maintaining Raypak 206A-406A or Versa series equipment, this 750mV pilot kit is the industry standard for restoring factory-spec combustion performance in natural gas configurations.

• Genuine OEM Component: Ensures exact fitment and maintains the safety certification of Raypak heaters.
• Integrated Thermopile: High-output 750mV pilot generator provides stable millivolt signals to the gas valve.
• Broad Compatibility: Supports a wide range of models including Raypak 055A, 105B, 155A-405, and R185B heaters.
• Quick Field Installation: Includes necessary mounting screws and technical geometry for immediate burner tray integration.

Is this pilot assembly compatible with propane (LP) units?
No, the Raypak 600525B is specifically calibrated for natural gas. For propane applications, a dedicated LP orifice or pilot kit is required to ensure correct gas flow and pressure.

What are the symptoms of a failing thermopile in this assembly?
Common indicators include the pilot flame lighting but failing to hold the gas valve open, or a millivolt output reading below the required 550-750mV range during a load test.

Does this kit include the pilot tubing?
This kit includes the pilot burner, thermopile, and mounting hardware. The existing pilot tubing is typically reused, though the connections should be inspected for corrosion or leaks during service.
