For a connection of a parking garage to a fuel fired appliance room, what alternative setup can be used if specific conditions are met?

The setup of a single door as an alternative connection for a parking garage to a fuel-fired appliance room is compliant under specific conditions outlined in the North Carolina Mechanical Code. A single door provides a pragmatic solution that ensures adequate separation between the potentially hazardous environment of the parking garage and the fuel-fired appliance room.

The code stipulates that proper ventilation and emergency access measures must be in place when using this configuration. By using a single door, the establishment can effectively control smoke and fumes while still allowing necessary access for maintenance or emergency services. This option can also enhance security and reduce the risk of unauthorized personnel entering sensitive areas, provided that the door meets the necessary fire resistance and is easily operable under emergency conditions.

In summary, the choice of a single door strikes a balance between safety, functionality, and code compliance, making it a suitable alternative connection under the prescribed conditions.
