What does the heating system inspection focus on during installation?

During the installation of a heating system in manufactured housing, the inspection primarily focuses on the examination of heating connections. This is crucial because these connections ensure that the heating system operates safely and effectively. Properly installed and secure connections are vital to prevent gas leaks, electrical issues, or inefficient heating. Inspectors assess both the quality of the materials used in these connections and the overall installation technique to ensure compliance with safety standards and building codes.

Understanding the condition and compliance of these heating connections also plays a significant role in the long-term functionality of the system. For instance, loose or improperly connected ducts can lead to heat losses, impacting the efficiency and performance of the entire heating system.

The other choices, while related to heating systems in general, do not encapsulate the primary focus of the heating system inspection during installation. For example, external airflow rates, energy consumption reviews, and fire hazard assessments are important aspects of a heating system's overall performance and safety but are addressed through different inspection protocols or evaluations, rather than being the central focus during the initial installation inspection.
