The correct answer is: Always

The requirement for safety valves to be connected to a boiler is critical for ensuring the safe operation of the boiler system. Safety valves are crucial components that protect the boiler from overpressure conditions, which can lead to dangerous failures or explosions. Regardless of specific conditions or boiler types, safety valves must always be present and connected to the boiler. This is a fundamental safety obligation that ensures pressure relief is available at all times during operation. While there are instances where specific regulations or inspector recommendations might impact how safety valves are utilized, the overarching rule is that they must always be connected. This constant readiness to relieve pressure is essential for maintaining safety standards across various operational scenarios, whether the boiler operates under lower pressures, is stoker fired, or is subject to inspections. The importance of consistent and reliable pressure control cannot be understated, thus illustrating why the connection of safety valves is an unwavering requirement.
