Lennox 31W62 Extension Kit
The Lennox 31W62 Vent Extension Kit (LB-115012A) is a mission-critical component for ensuring code compliance and operational safety on LGH/LGM/KG/ZG unit models with capacities ranging from 024-150, as well as SG 036 and 060 units. Designed to address clearance issues where exhaust vents are positioned too close to fresh air intakes, this OEM replacement kit redirects flue gases to prevent hazardous recirculation and eliminate ice formation on intake louvers during cold-weather cycles. Constructed from galvanized steel, the kit includes a vent transition, drain cap, heavy-duty bracket assemblies, and all necessary hardware for a secure field installation.
This HVAC vent extension is approved for applications where the B vent pipe extends no more than 3 feet above the unit top. Note that while the kit provides the specialized vent transition and mounting straps, technicians must supply the 3-inch diameter B vent pipe, tee, and cap to complete the venting system. Proper flue gas management is non-negotiable for maintaining combustion efficiency and protecting the heat exchanger from terminal moisture damage.
Key Benefits:- Ensures adherence to building codes regarding minimum distance between exhaust and fresh air intakes.
- Features a specialized vent transition designed to offset the flue to avoid overlapping combustion air louvers.
- Prevents frequent HVAC service calls related to ice blockage on intake screens during freezing conditions.
- Engineered with galvanized steel construction for maximum resistance to corrosion and thermal stress.
- Compatible with Lennox LGH, LGM, KG, ZG, and SG packaged units for seamless integration.
What unit models are compatible with the 31W62 kit?
This kit is specifically tailored for Lennox LG/LD/KG/ZG units (024-090), ZG units (092-150), and SG units (036 and 060). For SG 120 or larger tonnage models, verify the specific LB-series number as requirements may shift to 4-inch venting.
What does the kit include versus what is provided in the field?
The kit contains the vent transition, drain cap, brackets, straps, and fasteners. You must provide the 3-inch B vent pipe, 3-inch vent tee, and the final vent cap to finish the assembly.
Can the vent be extended further than 3 feet?
No. Engineering specifications and HVAC safety standards limit the vertical extension to 3 feet (.92m) above the unit top to maintain proper draft and structural integrity.
