Low System Pressure – Below 14 psi (1.0 bar) minimum

What does Low System Pressure mean?

The boiler requires a minimum system pressure of 14 psi (1.0 bar) for proper operation. If the pressure drops below this threshold, the boiler may not function or may display an error.

• Leak in the heating system piping or components
• Faulty pressure relief valve
• Air in the system
• Issue with the automatic fill valve

1. 1

   Check the boiler's pressure gauge to confirm the current system pressure.

2. 2

   Inspect all visible piping and connections for any signs of water leaks.

3. 3

   If you are trained and comfortable, repressurize the system according to the boiler's specific operating instructions.

4. 4

   If pressure continues to drop after repressurization or a leak is identified, contact a qualified heating technician immediately.
