Wet bottom boilers should be set above the floor a minimum of how many inches?

Wet bottom boilers should be set above the floor a minimum of 12 inches to prevent water accumulation and ensure proper drainage. This height is critical to maintaining the boiler's efficiency and safety. Setting the boiler at the proper elevation ensures that any potential leaks or moisture can drain away from the boiler equipment, reducing the risk of water-related damage and enabling better airflow and combustion efficiency.

Additionally, this height helps to facilitate maintenance activities, where the boiler components can be accessed more easily, ensuring that inspections and repairs can be performed safely and efficiently. Overall, adhering to this specification plays a vital role in the reliable operation of a wet bottom boiler system.
