Hayward FDXLGSV0002 Propane Gas Valve – Universal H-Series Pool & Spa Heater Replacement
Part # FDXLGSV0002 — a factory replacement propane gas valve designed for use with Hayward Universal H-Series Low-NOx pool and spa heaters. This valve regulates the flow of propane to the heater’s burner system to ensure safe, efficient ignition and combustion.
Key Features
- OEM-spec gas valve compatible with propane-fired Hayward H-Series heater models (e.g. H150FDP, H200FDP, H250FDP, H300FDP, H350FDP, H400FDP).
- Precisely regulates propane flow for stable flame, proper burner operation, and efficient heat output.
- Durable construction designed to handle typical pool-heater gas pressures and environmental exposure.
- Direct-replacement part — drops in place of the original valve without major modifications.
- Compatible with all control and safety systems originally designed for the heater (pressure switch, ignition module, venting, etc.).
Typical Applications
Use this valve when the existing gas valve in a propane H-Series heater fails — for example if it leaks, fails to open or close properly, or causes ignition issues. It’s also commonly replaced during maintenance or refurbishing to ensure continued safe operation.
Installation & Compatibility Notes
Before servicing, shut off the propane supply, turn off all power to the heater, and allow the unit to cool. Remove the old gas valve carefully, noting orientation and gas line connections. Install the new FDXLGSV0002 valve, reconnect gas lines and electrical connections, and pressure-test the system per manufacturer instructions to confirm there are no leaks. After startup, monitor ignition, burn quality, and heater operation to verify correct installation.
Why Choose This Gas Valve?
Choosing the genuine FDXLGSV0002 ensures proper fit, flow characteristics, and safety compliance for your H-Series heater. Using the correct valve protects the heater’s performance, avoids potential leaks or ignition problems, and helps extend the life of the unit.
Maintenance Tips
- Inspect gas valve and surrounding components yearly for signs of leaks, corrosion or wear.
- Check gas pressure and regulator settings per heater manual to ensure safe operation.
- When cleaning or servicing the heater, avoid disturbing valve seals — retorque fittings per spec if loosened.
- If the heater will be out of service for an extended period, shut off propane at the supply valve and relieve line pressure to safeguard internal components.
