Gas burner automatic
safety control
For 2-stage forced draught and combi oil/
gas burners
Possible flame detectors:
- Ionization probe
- Infrared flicker detector
INTRODUCTION
The gas burner automatic safety control MMI controls
and monitors blown gas- and combined burners of any
nominal thermal load (tested and certified according to
EN 298).
The automatic safety controls MMI 810.1 models 13, 33 and
35 can also be utilized for burners on fixed hot air heaters
(Direct air heaters according to DIN 4794).
Various types and model designations differentiate the
automatic safety controls with respect to the programme
times, as well as with regard to differing national standards.
