Honeywell VR8345M-4302 Universal 24 Vac Gas Valve - Reliable

In this review the Honeywell VR8345M-4302 is presented as a practical replacement gas valve for single stage gas-fired appliances, and its biggest draw is straightforward compatibility and installation for common HVAC repairs. The reviewer found the valve useful for furnaces and other appliances using IP, HSI or DSI ignition systems, and notes that the included Natural to LP conversion kit and reducer bushings make it ready for immediate use in many setups. Overall this review emphasizes the valve's fit, quality, and simple swap-in nature for service techs and experienced DIYers.

Key Features

• Universal 24 Vac operation: Works with standard 24 Vac control systems so it integrates with many single stage appliances without extra control changes.
• Natural to LP conversion kit included: The kit simplifies switching fuel types and avoids a separate purchase when converting to liquid propane.
• Reducer bushings included: Two 3/4 x 1/2 in reducer bushings are supplied so installers can adapt common pipe sizes quickly at the jobsite.
• Pressure regulator pre-set: The regulator setpoint at 3.5 inch water column provides an industry-standard starting point for most residential appliances.
• Direct or intermittent ignition capable: Compatible with direct ignition (DI) or intermittent pilot systems, giving flexibility for a range of ignition designs.

Who It's For

The VR8345M-4302 is best suited to HVAC technicians and experienced DIYers who need a dependable replacement valve for single stage gas-fired appliances such as furnaces, boilers or water heaters that use 24 Vac controls. Its inclusion of conversion hardware and reducer bushings makes it particularly practical when a field conversion from natural gas to LP or an adaptation of pipe sizes is expected.

Homeowners without mechanical experience or those with multi-stage or specialized appliance controls should consult a service professional or seek a valve specified for their exact appliance. If your system requires multi-stage control or has unusual pressure requirements, look for a model tailored to those needs.
