Lennox Combustion Analyzers

Overview

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.
