Lennox 89l97 Combustion Air Intake Extension Kit

Product Description

The LENNOX 89l97 is a combustion air intake extension kit designed for use with Lennox HVAC systems. It extends the combustion air intake piping, allowing proper routing of outside combustion air to the furnace burner assembly. This kit is installed by licensed HVAC technicians as part of venting and air intake configurations on gas furnaces. The extension kit ensures the intake draws from the correct location per installation requirements, maintaining safe and efficient burner operation.

This combustion air intake extension kit is intended for residential and light commercial gas furnace applications where the standard intake pipe length is insufficient for the specific installation layout. It is used when the furnace is installed in a confined space, utility room, or any location requiring additional intake pipe reach to an outside air source. Installers reference local mechanical codes and the furnace installation manual to determine proper intake pipe routing and total allowable length.

Key Features

• Extends combustion air intake piping for flexible furnace installation layouts
• Designed as a Lennox OEM accessory for precise fitment and code-compliant installation
• Supports proper outside combustion air sourcing for gas furnace burner assemblies
• Simplifies intake routing in confined or constrained mechanical spaces

Compatibility

Designed as an OEM Lennox accessory for gas furnace combustion air intake systems. Refer to the furnace installation manual and Lennox product documentation to confirm compatibility with the specific furnace model before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with gas furnace venting and combustion air requirements. Shut down the furnace and disconnect power before beginning any work on the intake system. Follow the furnace manufacturer installation manual and applicable sections of the International Fuel Gas Code for combustion air intake pipe routing, total equivalent length limits, and termination clearances. Do not modify the kit components or substitute non-OEM fittings.
