3 COMMISSIONING PROCEDURE
3.1 Overview
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.
If the MM is commissioned without an EGA then a combustion analyser is required to check the exhaust
gases. If the system does have an EGA, then a combustion analyser is not necessary as the EGA performs
all normal exhaust gas measurements. When commissioning oil fuel, a smoke detection device is also
necessary to check that the smoke generated is within safe limits.
Once a start position has been entered, the high fire position is entered next, then descending fuel/air
positions are entered consecutively until finally the low fire position is entered. CH1 and CH2 positions must
always be less than the ones previously entered; however CH3 to CH7 can be set lower or higher than the
previous position. CH7 is used for the draught servomotor (unlockable expansion feature).

On a newly installed system the following procedures should be carried out as listed:
1. Set up Fuel Valves Output Configuration Mode (refer to section 4 of this guide).
2. Check all interconnecting wiring between the MM and external components is correct.
3. Set options, parameters and expansion options required (refer to section 2).
4. Commission bottom blowdown module if optioned.
5. Commission water level probes and external level sensor if optioned.
6. Set up servomotors.
7. Program fuel/air positions.
On a previously commissioned system is it possible to omit steps 1 to 5.
