Burnham 81660143 Natural Gas Valve Honeywell VR8200C3005 24V Standing Pilot

The Burnham 81660143 is a natural gas valve designed for IN3-IN6 and P202-P206 series boilers. This combination gas control features Honeywell VR8200C3005 technology and operates on 24 volts with a standing pilot ignition system.

Key Features:

• 24-volt operation with standing pilot configuration
• 0.7-inch step opening for controlled gas flow
• 3.5-inch water column pressure rating
• 1/2-inch NPT inlet and outlet connections
• 1/4-inch pilot fitting included
• Dual automatic valve system with servo pressure regulator
• Manual reset safety shutoff for enhanced protection

This gas valve serves as a direct replacement for discontinued models 81660182 and VR8200C6008. The servo pressure regulator monitors outlet pressure to provide consistent main burner gas flow, while the solenoid-operated automatic valve opens on thermostat call for heat and closes when the heating cycle ends. The valve maintains pilot operation even during power loss, allowing for quick system recovery when power is restored.

Includes: Pilot compression fitting for 1/4-inch O.D. tubing, 1/2-inch x 3/8-inch straight bushing, hex wrench, and mounting hardware.
