Resideo VR8345K4809 Valve
The Resideo VR8345K4809 is a high-capacity universal electronic ignition gas valve designed for versatility in commercial and residential HVACR applications. Engineered for single stage gas furnaces and boilers, this valve features a 3/4 inch NPT inlet/outlet and handles up to 300,000 BTU/hr. As a slow opening gas valve, it ensures smoother ignition and quieter burner operation, reducing mechanical stress on the heat exchanger. It operates on standard 24VAC control circuits and is compatible with Intermittent Pilot (IP), Direct Spark Ignition (DSI), and Hot Surface Ignition (HSI) systems. This kit includes the necessary LP conversion kit and reducer bushings, allowing for field transitions between natural gas and liquid propane while accommodating 1/2 inch piping requirements.
Key Benefits
- Universal Compatibility: Replaces hundreds of OEM models from Resideo, Honeywell, White-Rodgers, and Robertshaw, reducing truck stock requirements.
- High Output Capacity: Rated for systems up to 300,000 BTU, making it suitable for larger rooftops and industrial unit heaters.
- Installation Flexibility: Includes 1/2 x 3/4 inch NPT bushings and a Honeywell gas valve LP conversion kit for immediate field adaptation.
- Reliable Sequencing: The slow opening feature prevents "roll-out" and ensures a stable flame pattern during the initial ignition cycle.
Common Questions
Can this valve be used with a standing pilot system?
No, the VR8345K4809 is specifically designed for electronic ignition gas valve configurations such as DSI, HSI, or Intermittent Pilot. It does not have a pilot gas supply or thermocouple connection for standing pilot applications.
How do I convert this valve for use with Liquid Propane?
The unit comes with a 393691 LP conversion kit. You must install the provided spring and orifice as per the technical manual to ensure proper manifold pressure for propane operation.
What is the orientation requirement for installation?
This valve can be mounted in any direction from 0 to 90 degrees from the upright position, providing significant flexibility in tight cabinet spaces.
