What should be done after cleaning or replacing the filtering element in a combustion heater fuel system?

After cleaning or replacing the filtering element in a combustion heater fuel system, it is crucial to pressurize the system and check all connections for leaks. This step ensures that the system is operating safely and efficiently. When a new filter is installed or the existing one is cleaned, there is potential for air or other contaminants to enter the fuel system. By pressurizing the system, you can detect any leaks that may have occurred during maintenance. This is vital because leaks can lead to fuel loss, compromised system performance, and safety hazards.

Ensuring that all connections are secure and leak-free is essential for maintaining the integrity of the fuel system and preventing any potential fire hazards. The practice of checking for leaks after any maintenance work not only promotes safety but also enhances the reliability of the heating system.
