  • 171-144 OBSOLETE

  • HEAT EXCHANGER IH115 & IL115

Bard part number 171-144 is an OEM heat exchanger used in Bard IH115 and IL115 gas heating sections, built to transfer heat safely from the burner system into the supply air stream while keeping combustion gases contained and properly routed to the flue. Replacing a damaged or leaking heat exchanger helps restore proper furnace operation, maintain safe venting performance, and resolve common failure symptoms like rollout issues, abnormal odors, or poor heat output. Because heat exchanger fit and furnace series details matter, confirm your exact unit model and serial number and match the factory parts list before ordering to ensure the correct 171-144 assembly for your Bard wall mounted equipment.
