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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends combustion air intake piping for flexible furnace installation layouts\u003c\/li\u003e\n  \u003cli\u003eDesigned as a Lennox OEM accessory for precise fitment and code-compliant installation\u003c\/li\u003e\n  \u003cli\u003eSupports proper outside combustion air sourcing for gas furnace burner assemblies\u003c\/li\u003e\n  \u003cli\u003eSimplifies intake routing in confined or constrained mechanical spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM Lennox accessory for gas furnace combustion air intake systems.
