Who is responsible for providing a complete control diagram and boiler operating instructions for each installation?

The responsibility for providing a complete control diagram and boiler operating instructions falls on the installer. This is because the installer is directly involved in the setup and configuration of the boiler system. When an installation is planned, the installer must ensure that all operational parameters, safety features, and control mechanisms are well-documented and conveyed through a control diagram.

The control diagram serves as a crucial reference for understanding the system's wiring, control sequences, and how different components interact within the larger HVAC setup. Additionally, providing boiler operating instructions is vital to ensure safe and efficient operation, allowing users to understand how to properly operate, maintain, and troubleshoot the installation. This documentation is not only essential for safety compliance but also for ensuring optimal performance of the heating system.

While technicians, inspectors, and owners play important roles in the process, the primary responsibility for creating and supplying these specific documents lies with the installer because they have the technical expertise and firsthand knowledge of the system's capabilities and requirements.
