Lennox 20J87 Inshot Burner
The Lennox 20J87 Inshot Burner is a critical OEM replacement component designed for high-efficiency gas furnaces and unit heaters. Engineered for precision, this 20J8701 identical burner measures 2.5 inches wide by 4.5 inches long and is constructed from durable stainless steel to resist corrosion and thermal stress. As a veteran technician knows, maintaining proper combustion performance depends on the swirl-stabilized flame pattern this part provides, which ensures optimal fuel-to-air mixture and prevents common ignition failures. This Lennox furnace burner is a direct replacement for the 20J8701 and 65246300, making it a versatile choice for a wide range of Lennox, Armstrong, and Ducane equipment. Replacing a fouled or cracked burner with this genuine OEM Lennox part restores system efficiency, stabilizes the flame signal for the flame sensor, and reduces carbon monoxide risks associated with improper combustion. Its compact, non-adjustable design allows for straightforward installation, ensuring your gas heating system operates at peak thermal output during high-demand cycles.
Key Benefits:- Exact OEM Specification: The Lennox 20J87 is the official replacement part, ensuring perfect fitment and alignment with the manifold orifice.
- Corrosion Resistance: High-grade stainless steel construction prevents scaling and rust that typically leads to delayed ignition or rollout.
- Universal Compatibility: Fully interchangeable with part number 20J8701, simplifying inventory for multiple Lennox-family furnace models.
- Enhanced Combustion: Features a swirl-stabilized design that produces a consistent, clean-burning blue flame for superior heat exchange.
- Simplified Service: Non-adjustable "inshot" design eliminates the need for field air-shutter adjustments, reducing setup time during HVAC maintenance.
Is the 20J87 interchangeable with the 20J8701?
Yes, the Lennox 20J87 is physically and functionally identical to the 20J8701. They are the same OEM part and can be used interchangeably in all listed compatible furnace and unit heater models.
What are the signs that my inshot burner needs replacement?
Look for signs of heavy oxidation, cracks in the burner head, or "lazy" yellow flames. If the furnace is experiencing delayed ignition or the flame rollout switch is tripping, the burners should be inspected for blockage or structural failure.
Does this burner work with LP (Propane) systems?
This burner is dual-fuel compatible; however, the specific BTU output and performance are determined by the gas orifice size and manifold pressure. Always verify the orifice matches the fuel type and input rating of the specific furnace being serviced.
