Lennox 71W36 Drain Hose

The Lennox 71W36 Drain Hose (Part Number: 102809-02) is a critical OEM replacement condensate hose engineered specifically for right-hand drainage configurations in Lennox gas furnaces and air handling units. This HVAC drain line is constructed from high-grade, chemical-resistant rubber designed to withstand the acidic nature of furnace condensate without degrading. As a genuine Lennox 102809-02 component, it ensures a factory-spec seal at the collector box or condensate trap, preventing moisture bypass that leads to cabinet corrosion or pressure switch trips. Professional technicians utilize this furnace drainage part for its exact-fit geometry, which eliminates the risk of kinking often found with universal tubing. By maintaining the integrity of the secondary heat exchanger drainage path, the Lennox 71W36 prevents water accumulation in the blower compartment and protects internal electrical components from premature failure. For contractors, this part is essential for restoring system performance to original factory standards during routine maintenance or HVAC drainage system repairs.

Key Benefits:

• Compatible with a wide range of Lennox high-efficiency furnaces (92AF to 95AF2 series).
• Precision-molded right-hand design ensures seamless integration with factory drainage ports.
• Durable rubber construction resists mold and mildew growth common in damp HVAC environments.
• Prevents condensate blockages that can cause system shutdowns or water damage.
• Direct Lennox OEM replacement reduces installation time compared to generic alternatives.

Common Questions:

Is this hose compatible with left-hand discharge units?
No, the Lennox 71W36 is specifically molded for right-hand application. For left-hand configurations, check your technical manual for the corresponding left-hand part number to ensure proper slope and drainage.

Does this part include the hose clamps for installation?
This item typically includes the Lennox 102809-02 drain hose only. We recommend reusing existing OEM clamps or sourcing new stainless steel spring clamps to ensure a leak-proof connection to the condensate trap.

What causes this drain hose to fail?
Standard wear occurs due to prolonged exposure to acidic condensate and thermal cycling. If you notice cracking, brittleness, or water pooling near the vestibule panel, the drain hose (UH) right should be replaced immediately.
