• Heat Exchanger For Dch

Bard part 171-194 is an OEM heat exchanger assembly used in Bard DCH series wall-mounted gas heating units, built to transfer heat safely and efficiently from the burner section into the supply airstream. If your DCH unit has a cracked exchanger, fails a combustion safety check, or shows signs of heat-related shutdowns, replacing the exchanger is the correct repair to restore reliable heating performance while keeping the combustion path properly isolated from the air delivered to the space. Because heat exchangers are model and capacity specific within the DCH lineup, confirm the complete unit model and serial number and cross-reference your Bard parts list before ordering to ensure proper fit and safe operation.
