BURNER START-UP SEQUENCE
The MM goes through a series of internal checks and flame safeguard checks before starting up the burner; these
are relevant to the burner application. Any errors or lockouts which might occur in the start-up sequence will provide
information on the time and date they have occurred, and the phase in which it occurred. If any errors or lockouts
occur, please contact Autoflame Engineering Ltd or your local Autoflame Technology Centre.
The following start-up sequence is shown for an example burner application. The system has been set up with these
burner control features:
• Firing on gas.
• 1 Valve proving system – No vent valve.
• Intermittent pilot.
• UV scanner.
• Air switch on T54.
• Gas Pressure sensor – VPS and pressure limits checked.
• VPS operates before start-up.
• Pre-purge and post-purge.
