Subject: flame failure Не могу понять что означает в данном контексте flame failure safety system и flame failure safety relay. Они сами гасят пламя или или это системы которые предотвращают погасание пламени.The burner flame failure and burner safety systems are housed separately from the burner. They comprise flame failure safety relays connected to a flame rectification type probe, to monitor "start" flame and "main" flame, which automatically shut off gas and air supply valves in the event of flame failure.
