What should be done if the boiler pump starts but there is no ignition?

If the circulator starts but ignition does not occur, check the following points: 1. Gas Supply: Ensure the gas tap is fully open (page 14). 2. Operational Safeties: Check if a fault light is illuminated on the control panel. If the exhaust safety light (C models) or air circuit fault light (F models) is on, try setting the selector to '0', wait 10 seconds, then set it to 'I' (page 16). If the boiler went into safety mode after three unsuccessful attempts (e.g., due to a gas cut-off), a fault indicator will light up (page 16). 3. Lack of Water: If the power indicator flashes, it indicates a lack of water in the installation (page 16). Verify that the pressure is between 1 and 2 bars on the manometer (page 14).
