Who must be contacted before welding on a non-residential warm air heat exchanger?

Welding on a non-residential warm air heat exchanger carries significant safety and regulatory considerations, which is why it is essential to involve the manufacturer before proceeding. The manufacturer possesses the specific knowledge regarding the design and construction of the heat exchanger, including materials used, appropriate welding techniques, and any necessary procedures that must be followed to maintain the integrity and safety of the system. This contact ensures that any welding operations comply with the original specifications and safety standards set forth during the design and production of the heat exchanger.

Involving the manufacturer not only helps prevent potential safety hazards but also ensures that the equipment remains under warranty and meets all applicable codes and standards. This precaution is critical in maintaining optimal performance and preventing any future issues that may arise from improper modifications or repairs.
