Warranty & Compatibility

Installation Information

Gas valve replacement requires access to the burner tray, gas manifold, pilot tubing, and heater electrical connections.

Before servicing:

• Disconnect electrical power to the heater
• Shut off the natural gas supply
• Allow the heater to cool completely
• Disconnect the gas supply line
• Inspect the burner manifold and pilot system
• Verify all gas connections for leaks after installation

The gas-flow direction indicated on the replacement valve must be observed during installation. Pipe-joint compound used on threaded connections must be suitable for fuel-gas service.

Gas valve installation, adjustment, and leak testing should be completed by a qualified gas-heater service professional.
