• 2 Burner Heat Exchanger

Bard part number S171-254 is an OEM 2 burner heat exchanger assembly used in select Bard wall mounted gas electric HVAC units to transfer heat safely and efficiently from the burner section into the supply air stream. Replacing a cracked, rusted, or leaking heat exchanger helps restore proper heating performance, supports correct combustion and airflow through the furnace section, and helps prevent nuisance limit trips caused by overheating. Because heat exchanger designs and burner counts vary by model and input rating, match S171-254 to the exact Bard model and serial number data before ordering to ensure correct fit and safe operation.
