The requirement for using a furnace for temporary heat in a residential construction is that the furnace must be installed on a finished concrete floor or slab that is at least 4 inches thick. This requirement is crucial for several reasons.

First, a sturdy and level foundation is necessary to ensure the safe operation of the furnace. An inadequate surface could lead to instability or uneven heating, which could result in performance issues or potential hazards. A concrete slab that meets the thickness requirement provides the necessary support and durability for the furnace during construction activities.

Additionally, using a proper base helps to protect the furnace from moisture and debris, which are common in construction environments. It also minimizes the risk of fire and other safety issues that could arise from improper placement. Overall, this requirement ensures the safe and efficient operation of the furnace while providing temporary heating to the construction site.
