MM Application Possibilities
2.8.3 No Air Servomotor
Some burner applications use natural draught to supply air for combustion without the need for air
blower for forced draught and there is no air damper, so the air supplied to the burner is at
atmospheric pressure. In such applications there is no need for control on the air channel and only the
fuel channel requires controlling.
The Mini Mk8 MM allows the system to be set so that the burner is commissioned with channel 1
servomotor only to control the fuel flow. This configuration can also be used for pre-mix burners
where the fuel to air volume ratio is not varied. In these applications, channel 1 is sued to vary the
volume of combined air and fuel.
The gas servomotor is wired as normal to the MM, and option 4 must be set to ‘No Air Channel.’
Option 8 must be set to ‘Channel 1 only.’
Figure 2.8.3.i Commissioning No Air Servomotor
The commission procedure follows the normal steps but with channel 1 servomotor only.
For more information on using the Mini Mk8 MM on an atmospheric burner or pre-mix burner and
what limit switches or purge delay is required, please contact Autoflame Engineering Ltd.
