The AO SMITH 100265720 is an LP (liquid propane) conversion kit designed for use with FBA N3 series G40S40 water heaters fitted with aluminum exterior components. This kit provides the necessary hardware and components to convert a compatible natural gas water heater to liquid propane operation. Conversion kits of this type are typically installed by licensed plumbers or gas service technicians and must comply with applicable local fuel-gas codes. The aluminum exterior designation indicates this kit is matched to units with aluminum-clad or aluminum-jacketed housings.
This kit is suited for residential water heating applications where LP fuel is the available energy source. It is intended for use on AO SMITH FBA N3 series G40S40 water heaters with aluminum exterior configurations. Installation is required any time a unit is relocated from a natural gas service area to an LP-supplied site, or when a replacement unit must match an existing LP fuel setup. Only technicians trained in gas appliance service should perform this conversion.
