Lennox 44W52 Collector Box

The Lennox 44W52 Collector Box (also identified by part number 102107-01) is an essential OEM component for high-efficiency gas furnaces. Located at the secondary heat exchanger outlet, this collector box is engineered to manage the disposal of acidic furnace condensate and combustion byproducts. By facilitating proper condensate drainage, the 44W52 protects the internal furnace heat exchanger from moisture-induced corrosion and premature failure. This genuine Lennox replacement part ensures the airtight seal required to maintain proper static pressure and safe inducer motor operation.

For field technicians, the 44W52 provides a precise fit for specific G43UF series units, including the G43UF-36C-090-4 and G43UF-48C-090-6 models. Its durable, corrosion-resistant construction is specifically designed to handle the thermal stress and chemical exposure common in condensing furnace environments. Replacing a cracked or clogged collector box is critical for resolving pressure switch lockout codes and preventing water from backing up into the inducer housing, which can lead to system shutdowns during peak demand.

Key Benefits

• OEM Compatibility: Engineered for a perfect fit on Lennox G43UF series high-efficiency furnaces.
• System Protection: Optimizes condensate flow to prevent moisture buildup in the secondary heat exchanger.
• Durable Construction: Built with high-grade, corrosion-resistant materials to withstand acidic furnace runoff.
• Performance Restoration: Essential for maintaining proper vacuum and preventing furnace pressure switch issues.

Common Question

How do I know if my Lennox collector box is failing?
Common indicators include water pooling at the base of the furnace, condensate drain backups, or the system throwing "pressure switch open" error codes. Technicians often find hairline cracks in the plastic housing or clogs at the drain ports that prevent the inducer from pulling a proper vacuum.
