Ao Smith 100109295 Fv Pilot Assembly High Altitude Ng

Product Description

The AO SMITH 100109295 is a standing pilot assembly designed for use in flued vent (FV) water heater systems fueled by natural gas. This high-altitude pilot assembly maintains a stable pilot flame that proves ignition to the main gas valve, allowing the burner to fire and heat the water supply. It is rated for a temperature of 190 degrees F, making it appropriate for high-altitude installations where air density affects combustion performance. Licensed plumbers and water heater service technicians are the primary installers of this component.

This pilot assembly is designed for heating applications and is specifically configured for high-altitude use, where standard pilot assemblies may fail to sustain a reliable flame due to reduced atmospheric pressure. It is a direct-replacement component intended for FV-style natural gas water heater units. High-altitude installations typically apply to sites at elevated elevations where equipment must meet adjusted combustion requirements.

Key Features

• High-altitude configuration supports reliable pilot operation at reduced atmospheric pressure
• Rated for 190 degrees F temperature applications
• Designed for natural gas (NG) flued vent water heater systems
• OEM-style replacement assembly for compatible AO SMITH FV water heaters

Compatibility

Designed as an OEM-style replacement pilot assembly for AO SMITH flued vent natural gas water heaters requiring a high-altitude pilot configuration.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater service technician. Before servicing, shut off the gas supply at the shutoff valve and allow all components to cool completely. Follow all applicable local codes and the manufacturer service documentation when routing or reconnecting the pilot tubing and thermocouple leads. Never restore gas supply or attempt ignition without first confirming all connections are leak-free using an approved leak-detection method.
