Includes corrosion-resistant bolts designed to handle the acidic condensate typical in high-efficiency ARM models

Why is my pilot failing to stay lit

the LH33WZ017 should be replaced if the ceramic insulator is cracked or if the metal rod shows significant pitting

Environmental Protection: The NEMA 4X rated housing ensures protection against harsh wash-down environments and corrosion

which eliminates the need for separate in-line flow checks

Lennox 83L23 Gasket 320819-301 Includes corrosion-resistant bolts designed toThe Lennox 83L23 Collector Box Gasket is a critical OEM replacement component engineered for high efficiency Lennox G24 and G32 series furnaces. This furnace collector box seal provides a high temperature resistant interface between the collector box and the heat exchanger, ensuring a pressurized, airtight seal essential for proper venting and combustion. Over time, original gaskets can degrade due to thermal cycling, leading to pressure switch faults
