Page 4: Safety
1.4. Safety - If there is no flame, this is detected by an ionisation sensor and the gas vales are immediately closed. - The thermal protection of the heat exchanger is ensured by two thermostats. The first, which is automatically reset, protects against insufficient air flow (obstructions, fan failure). -
