MMG 810.1 / 811.1
For 2-stage forced draught and combi oil/gas
burners
Suitable flame detectors:
- Ionisation probe
- UV sensor
- Infra-red flicker detector
INTRODUCTION
The MMG burner control box is capable of controlling
and monitoring forced draught and combi oil/gas burners
of any nominal rating (tested and approved as per EN 298).
The MMG 810.1 model 33 control boxes are also suitable for
use in stationary warm air generators (Direct air heaters
according to DIN 4794).
Different type and model designations identify the control
boxes according to varying national standards, and to some
extent, according to programme times.
