To ensure proper operation of wall heaters, adherence to the manufacturer's installation instructions is crucial. These instructions provide specific requirements regarding the placement, electrical connections, venting, and safety measures that are tailored to the design and specifications of that particular heater model. Following these guidelines helps ensure not only efficiency but also safety, preventing issues such as improper heating, increased energy consumption, or even potential fire hazards.

While local building codes are important and often incorporate manufacturer specifications, it is the manufacturer's instructions that provide the definitive guidance specific to that equipment. Compliance with OSHA regulations generally pertains to workplace safety and does not specifically address the installation of wall heaters in residential or commercial settings. National Fire Protection Association guidelines, while essential for safety standards, do not replace the necessity of the manufacturer's detailed instructions for individual devices.
