| Interval | Action | |----------|--------| | | Check pressure gauge (1.0–1.8 bar cold). Symptom check: unusual noises, flames visible, error codes. | | Every 6 months | Visually inspect flue terminal outside for blockages. Check for water leaks around the boiler. | | Annually | Must be serviced by a Gas Safe engineer. Includes: cleaning the main heat exchanger, checking combustion parameters, testing condensate trap and siphon, checking ignition and flame sensing electrodes. | | Every 2 years | Replace the internal condensate siphon seal (preventive against flue gas leakage). | Watch the pressure gauge on the front control panel
