Application
The 17F33 Collector Box is used in Lennox high-efficiency gas furnaces where condensing operation produces both flue gases and liquid condensate. It works in conjunction with the draft inducer blower assembly to ensure a sealed, efficient venting pathway. Proper collector box integrity is essential to prevent flue gas leaks, maintain negative pressure in the heat exchanger, and protect indoor air quality.
Why Choose a Genuine Lennox OEM Part?
Using a genuine Lennox replacement collector box ensures compatibility, reliability, and warranty compliance. Aftermarket substitutes may not meet the precise dimensional and material specifications required for safe, efficient operation.
