Resideo VR8204M1091 Valve

The Resideo VR8204M1091 is a 24V intermittent pilot dual automatic combination gas valve engineered for precision fuel control in residential and light commercial gas-fired appliances. This single-stage valve features a 1/2" x 1/2" inlet/outlet and is rated for 150,000 BTU/hr capacity. Designed with a standard opening and a 3.5" WC regulator setting, it provides stable manifold pressure for consistent combustion. The unit includes dual automatic safety shutoff valves to meet strict code requirements and a servo pressure regulator for high-performance operation. It serves as a direct cross-reference for R37933B002 and is compatible with S8600, S8610, and S8670 ignition modules. The package includes a 3/4" straight flange, a 1/2" x 3/8" reducer bushing, and an LP conversion kit, allowing for field flexibility in natural gas or liquid propane applications. A 1/8" NPT pressure tapping is provided for simplified field testing and troubleshooting.

Key Benefits for Technicians

• Universal Application Compatibility: Optimized for use in gas furnaces, boilers, and unit heaters requiring an intermittent pilot ignition.
• Enhanced Field Versatility: Included LP conversion kit and reducer bushings facilitate immediate adaptation to varied fuel types and piping configurations.
• Compact Form Factor: Straight-through body pattern with top-side wiring terminals allows for easier installation in tight vestibules.
• Superior Low-Fire Support: Maintains reliable regulation across a flow range of 20 to 200 CFH, supporting equipment as small as 20,000 BTU/hr.
• Reliable Cold-Start Performance: Rated for an ambient temperature range of -40°F to 175°F, ensuring operation in unconditioned mechanical rooms.

Common Questions

Is the VR8204M1091 used for standing pilot systems?
No, this valve is specifically designed for intermittent pilot (electronic ignition) systems. It is not compatible with standing pilot thermocouples.

Can this valve be mounted in any orientation?
The valve is rated for mounting from 0 to 90 degrees from the upright position. Avoid mounting the valve upside down.

How do I test the manifold pressure on this unit?
Utilize the 1/8" NPT pressure tapping located on the outlet side. Ensure the plug is resealed with pipe sealant after testing.
