The minimum required height of a vent termination point above a newly converted sun deck is set to ensure that the venting system operates effectively and that the discharged gases do not create hazards for occupants or interfere with outdoor activities. In this case, the requirement of a 7-foot height is established to promote adequate dispersion of any gases away from the area where people might gather and ensure compliance with safety standards.

This height helps prevent the accumulation of potentially harmful exhaust fumes in the vicinity of the sun deck, where people may be relaxing or socializing. Adequate vent height is crucial for both safety and comfort, as it reduces the risk of inhalation or exposure to vented gases. Therefore, the choice of 7 feet is aligned with these safety principles and regulations.

Other options propose heights that are either too low to provide sufficient dispersion or do not meet the established codes for vent termination in relation to habitable areas, which necessitate a taller termination point to maintain air quality and safety in outdoor spaces.
