Under-floor appliance access opening for none fuel gas appliances: minimum size is 30 x 30 inches.

Explanation:
Access openings under a floor must be large enough to allow safe service and removal of the appliance. A 30 by 30 inch opening provides sufficient width and height to maneuver the appliance through the opening, while still leaving room to reach controls, disconnect or reattach connections, and work around any venting or piping. This size balances practicality and safety: smaller openings make removal and servicing difficult or impossible, whereas this minimum ensures the technician can perform needed tasks without obstructed access.
