What is the minimum number of days required to notify the state before installing a new boiler?

The correct answer outlines that a minimum of 30 days' notice is required before installing a new boiler. This timeframe is established to ensure that the proper state authorities have sufficient time to review plans, conduct inspections, and ensure compliance with safety regulations. By notifying the state 30 days in advance, it allows for coordination among regulatory bodies to confirm that the proposed installation meets all necessary codes and is safe for operation. This proactive approach helps prevent potential issues during installation and ensures that all safety protocols are adhered to, thereby protecting both the operators and the public from possible hazards associated with boiler operations.
