- Loosen the tightening bolt (refer to Figure) and push
the adjustment ring with the squeezing bolt until the
nominal value has been reached.
- Squeeze the bolt with 1.0 + 0.5 Nm and put security
varnish on it.
WARNING
The CO
2
setting depends on the viscosity and geodetic
altitude (0.1 % for each 100 m). In the case that the CO
2
value cannot be adjusted according to the rules, act as
follows:
- Check if there is any damage on the air side of
the burner head and replace if there is a damage.
- Check the pressure of the fuel pump and replace
the pump if necessary.
- Replace the nozzle
- Measure the revolution of the burner engine
- Check to see whether or not the assembly at the
cable joints is correct.
6.3 Testing the individual elements
6.3.1 The resistance check of the heat sensor (only
the heating devices equipped with the control
device 1563/64)
The heat sensor should exhibit the values shown in the
graphic below at the electrical test conducted with the
digital multimeter. The resistance measurement should
be carried out preferably at 20
0
C and approximately at
100
0
C (the sensor will be immersed in water).
