Reznor 204301 Gas Valve

When you are out in the field servicing a Reznor unit heater, you need an exact replacement to ensure the burner manifold pressure remains within spec. The Reznor 204301 Gas Valve is the genuine OEM solution for natural gas applications, factory-calibrated to a 5" water column (WC) output. This Honeywell VR8205 series valve (specifically VR8205M2955) is a single-stage, 24V gas valve that provides consistent flame regulation and safety shut-off performance. With its standard 1/2" NPT inlet and outlet, it integrates directly into the existing gas train without the need for additional adapters or field modifications. As a critical HVAC replacement part, it is engineered for high-cycle industrial environments where reliability is non-negotiable. Whether you are performing a seasonal tune-up or an emergency repair, utilizing genuine Reznor heating parts ensures the unit maintains its original agency listings and firing rates. Always verify your manifold pressure with a manometer after installation to ensure the 5" WC setpoint matches the rating plate requirements of the specific Reznor unit heater model you are servicing.

Common Questions:

Can I use the Reznor 204301 valve for propane (LP) applications?
No, this specific model is a natural gas valve calibrated for 5" WC. For LP conversions, you would need the appropriate conversion kit or an LP-specific valve to ensure safe manifold pressures.

Is this a direct crossover for the Honeywell VR8205 series?
Yes, this is the Honeywell VR8205M2955, which is the standard valve utilized across many Reznor heater platforms. It is the technician’s choice for maintaining factory specs.

What should I check if the valve isn't opening?
First, verify that the 24V coil is receiving constant voltage from the control board. If voltage is present but there is no gas flow, check for a clogged pilot orifice or verify that the inlet pressure does not exceed the maximum rating of the gas control valve.
