Specifications

  • Type: Gas Valve Assembly
  • Flue Type: Natural Gas

Product Overview:
Functioning as a fuel control component within gas supply systems, the Lochinvar & A.O. Smith 100172009 Natural Gas Valve Assembly manages natural gas flow in applicable equipment assemblies. This gas valve assembly forms part of the equipment gas train and provides controlled fuel passage for designated Lochinvar and A.O. Smith gas-fired heating systems. Specified for Natural Gas applications, the component supports fuel delivery within compatible commercial and residential equipment.

Gas Valve Assembly Operation:
Within the equipment fuel train, natural gas is directed through the valve assembly toward the burner circuit. The internal valve mechanism regulates this passage according to the heating system's operating sequence. Its position within the gas train allows the assembly to manage fuel delivery between the supply line and burner circuit.

Gas Supply Line Placement:
Positioned within the equipment gas supply line, the assembly forms part of the Natural Gas fuel train. Its main body ports provide the designated connection points for gas flow through the equipment. The valve assembly therefore serves as the fuel-control interface between the gas supply path and the applicable heating equipment.

Replacement Guidelines:
Replacement may be appropriate when the gas valve assembly shows physical damage or no longer performs its intended fuel-control function. For the Lochinvar & A.O. Smith 100172009, conditions that may indicate replacement include damaged connection ports, cracked valve-body components, gas leakage, or failure to properly control gas passage. A replacement assembly restores the specified gas valve configuration when the existing component is no longer suitable for service.

Common Failure Symptoms:

  • Gas leakage around the main connection points
  • Gas odor detected near the valve assembly, requiring immediate professional evaluation
  • Failure of the valve assembly to permit gas passage when required by the equipment
  • Failure to properly stop gas passage when required by the equipment controls
  • Visible cracking or physical damage to the valve body
  • Stripped, cross-threaded, or damaged gas connection ports

Equipment Compatibility:
The Lochinvar & A.O. Smith 100172009 is specified as a Natural Gas valve assembly for applicable Lochinvar and A.O. Smith equipment. Before selecting a replacement, verify the equipment model, fuel type, existing part number, and applicable manufacturer documentation to confirm the required valve assembly.
