The correct answer is based on the necessity of adhering to the manufacturer's directions for installing a commercial clothes dryer. The manufacturer's installation instructions are specifically designed to ensure that the equipment is installed safely and operates efficiently. These directions often include critical information about clearances, required power supply specifications, venting methods, and other essential safety measures tailored to that specific model.

Following the manufacturer's guidelines helps prevent operational issues that can arise from improper installation, which can lead to equipment failure, fire hazards, or non-compliance with relevant safety regulations. While the fire marshal's directions and local building codes are important for aspects of safety and compliance, they may not contain the detailed specifications needed for the particular dryer. Consequently, the manufacturer's directions take precedence in ensuring proper installation that meets both manufacturer specifications and broader safety standards.
