Ao Smith 100271888 Spark Igniter Assembly Kit

Product Description

The AO SMITH 100271888 is a straight spark igniter assembly kit designed for gas water heater applications. The igniter assembly initiates combustion by generating a high-voltage spark at the burner, triggering ignition of the main gas supply. This component is a direct service part intended for replacement during routine maintenance or after ignition failure diagnostics. Installation is typically performed by licensed plumbers or gas service technicians familiar with water heater combustion systems and applicable codes.

This igniter assembly is suited for residential gas water heater installations where the original straight-configuration igniter has failed or shows signs of wear. The straight geometry is a key fitment detail, distinguishing it from angled or bent igniter configurations used in other units. Technicians should confirm the straight igniter style matches the original assembly before installation.

Key Features

• Straight igniter configuration for direct OEM-style replacement
• Spark-type ignition for reliable combustion initiation at the gas burner
• Designed as a service assembly kit, including the igniter component
• Intended for licensed gas service or plumbing professionals

Compatibility

Designed as an OEM-style replacement igniter assembly for AO SMITH gas water heaters requiring a straight spark igniter configuration. Confirm original part number and igniter geometry before ordering.

Installation Notes

Shut off the gas supply and disconnect power to the water heater before beginning any igniter service work. This installation should be performed by a licensed plumber or gas technician in accordance with local codes and IFGC guidelines. Inspect the igniter wire harness and electrode condition before installing the new assembly. Do not overtighten the igniter mounting or force the electrode into position, as ceramic insulators are fragile.
