What should be attached to the boiler along with the manufacturer's rating data?

The manufacturer's rating data should be accompanied by a nameplate because the nameplate serves as a crucial identification and specification tool for the boiler. It provides important information such as the model number, serial number, and specific operational parameters set by the manufacturer. This data is essential for ensuring that the boiler is operated within its designed capabilities and according to the manufacturer's guidelines.

Having this information readily available promotes safer operation, helps in compliance with local codes, and aids in maintenance and inspection processes. The nameplate is typically affixed directly to the boiler itself, making it a reliable source of information in the event of troubleshooting or mechanical issues. Thus, it is vital to ensure that the nameplate is present whenever the boiler is installed or inspected.
