Burnham Boiler 109621-01 Gas Valve

The Burnham Boiler 109621-01 Gas Valve is a critical OEM replacement component designed for precision fuel regulation in residential and light commercial cast iron boilers. This Honeywell VR8204H1006 equivalent functions as a combination redundant gas valve, integrating a manual valve, two automatic operators, and a pressure regulator into a single compact footprint. This specific model is a high-capacity 1/2" x 1/2" NPT intermittent pilot gas valve engineered for 24V, 60Hz systems. It is the direct service replacement for the Burnham 81660160, ensuring drop-in compatibility and maintaining the original safety certification of the appliance. The 109621-01 gas control is rated for natural gas (NG) applications and provides a standard opening characteristic for stable ignition sequences. When troubleshooting Burnham series 2 boiler gas valves, this unit resolves issues related to solenoid failure or internal diaphragm leaks, ensuring the manifold pressure remains within manufacturer specifications for optimal combustion efficiency.

• Direct OEM Replacement: Replaces legacy part number 81660160 without requiring piping modifications.
• Intermittent Pilot Operation: Designed for modern electronic ignition systems to reduce standby energy loss.
• Internal Pressure Regulation: Factory-set for standard natural gas WC, adjustable for specific field requirements.
• Compact Straight-Through Design: Simplifies installation in tight vestibules found in residential boiler cabinets.
• Redundant Safety Shutoff: Features dual automatic valves to ensure positive gas shutoff upon loss of flame signal.

Is the Burnham 109621-01 compatible with LP gas?
This valve is factory-configured for natural gas. For propane applications, a specific LP conversion kit compatible with the VR8204 series must be used to ensure correct manifold pressure.

What are the symptoms of a failing boiler gas valve?
Common indicators include the pilot sparking without the main burner igniting, inconsistent manifold pressure leading to "rumbling," or the valve failing to close completely after the thermostat is satisfied.

Can I use this valve to replace a standing pilot system?
No, the 109621-01 is specifically for intermittent pilot (IP) systems. It does not have the manual "Push-to-Light" thermocouple connection required for standing pilot boilers.
