Which requirement is NOT associated with the installation of connectors in venting systems?

The requirement regarding the installation of connectors in venting systems typically emphasizes ensuring that the system functions effectively and safely. In this context, the option indicating that installation must allow for future modifications is not a standard requirement associated with vent connectors.

Connectors primarily need to be installed in a way that optimizes performance regarding safety and efficiency of the venting system. This includes positioning the connectors close to the appliance to minimize potential issues such as backdraft or obstruction, sealing them properly to prevent leaks, and complying with specified positioning guidelines according to room dimensions and appliance clearance standards.

While future modifications might be a consideration in planning and design, the primary responsibility in the installation phase is focused on ensuring compliance with established safety guidelines and performance standards rather than accommodating alterations that may happen at a later date. Therefore, the emphasis is on immediate installation integrity rather than future adaptability.
