Homeowners should regularly check the pressure gauge on the front panel—typically, this should sit between 1.0 and 1.5 bar when the system is cold. If the pressure drops, the system may require topping up via the external filling loop. Always keep the area around the flue terminal clear of obstructions to ensure safe combustion.
