Allied Air 68w64 Return Air Base 24.5 in Gas Furnace

Product Description

The ALLIED AIR 68w64 is a return air base designed to provide a proper foundation and air pathway at the base of a gas furnace installation. It mounts beneath the furnace cabinet to direct return airflow into the unit from below, keeping the installation clean and code-appropriate. The 68w64 is sized for 24.5-inch-wide gas furnace cabinets, making it a direct fit for that specific cabinet width. HVAC technicians and installers use this type of component during new furnace installations or when replacing aging base assemblies on existing systems.

This return air base is suited for residential gas furnace installations where a bottom-return configuration is required. It supports upflow furnace setups where return air enters from the bottom of the cabinet. The 68w64 is specified for use with 24.5-inch-wide gas furnace cabinets, which is a standard residential furnace width. Installers working on replacement or new-construction projects should confirm cabinet width before ordering to ensure proper fit.

Installation Notes

Installation of a return air base should be performed by a licensed HVAC technician. Power to the furnace must be disconnected at the breaker before beginning any work on or around the furnace cabinet. Ensure the base is properly seated and sealed to prevent air bypass, which can reduce system efficiency and create pressure imbalance. Follow all local mechanical codes and manufacturer instructions during installation.
