10 Fully Metered Combustion Control

10.3.3 Commissioning
Important Note: Prior to commissioning, the fuel and air servomotors must be calibrated to ensure
that the position of the valves and damper correspond to the potentiometer feedback signal as
displayed on the MM. When the valve is fully closed, the MM should display zero degrees. If it does
not, please adjust the servomotor potentiometer.
The commissioning procedure as described must be strictly adhered to. Anybody
commissioning an MM must be trained in operating combustion equipment safely. The
Autoflame products must only be installed, set up, commissioned and adjusted by an
Autoflame certified technical engineer.
The fundamental idea of the system is to set a fuel valve position and then set a
corresponding air damper position. Care must be taken when adjusting the fuel and air
positions so as not to create any unstable or hazardous combustion conditions, e.g.
moving the fuel valve to the open position without increasing the air damper position.
Improper use may result in property damage, serious physical injury or death.
The equivalence ratio and excess air provided on the MM are calculated displays
based on setup and inputs from external sources. The exhaust gases should be
monitored using a combustion analyser at all times during commissioning and for any
changes to the combustion curve.
WARNING: COMMISSIONING OR BURNER START-UP MUST ONLY BE
CARRIED OUT BY A FACTORY TRAINED TECHNICIAN.
