What is the minimum distance that vent termination can be located from an interior corner?

The minimum distance that vent termination should be placed from an interior corner is three feet to ensure safe operation and proper venting performance. This distance helps prevent the risk of recirculating exhaust gases, which can occur if the vent is too close to corners or walls. Adequate spacing allows for better air movement and reduces the potential for backdrafts that could lead to hazardous conditions. Compliance with this distance regulation is critical for both safety and efficiency in HVAC systems, ensuring that combustion products are effectively dispersed away from building structures.

Maintaining this distance also aligns with industry best practices and code requirements, which typically state similar measurements to promote safety and to optimize the functioning of HVAC equipment.
