Measuring the surface loss
The surface loss is the temperature that the burner emits via
the surface.
NOTE!
The Special Wall Temperature Probe is needed to measure
the surface loss (see accessories).
Before measuring the surface loss, it is necessary to enter
certain data. For that purpose all partial areas of the burner
must be considered that do not adjoin directly to other instal-
lations and/or walls and floors
