What must be considered when using a furnace for temporary heat in a residence under construction?

When using a furnace for temporary heat in a residence under construction, it is crucial to follow proper installation procedures to ensure safety and functionality. The requirement for the furnace to be installed on a finished concrete floor or slab that is at least 4 inches thick and 6 inches larger than the base of the furnace is based on several important factors.

Firstly, a solid concrete base provides stability for the furnace, minimizing vibrations and ensuring it operates efficiently without risk of tipping or moving during use. This is particularly important in a construction site where there may still be ongoing work, materials moving around, and potential disturbances.

Secondly, the thickness of the concrete slab serves as a fire barrier, helping to protect against any heat generated by the furnace potentially igniting construction materials or the surrounding environment. This consideration is essential in a setting where flammable materials are likely to be present.

Finally, the dimensional requirements ensure that there is enough space around the furnace, which is crucial for air circulation, maintenance access, and safe operation. Adequate spacing prevents overheating and reduces the risk of fire hazards.

Overall, these requirements are designed to promote safety, efficiency, and proper operation of the furnace in a construction environment, making the choice of a sturdy and appropriately-sized foundation a critical consideration
