Important information about
resetting the burner
■
If the burner switches off again
because of a fault during
starting, it may only be reset
after waiting 5 mins. approx.
■
Resetting again should be strict-
ly avoided. There is a danger of
explosion.
7. Prior to resetting the STB, make
sure to analyse the causes and
eradicate them.
The following causes can be
possible:
- The equipment was unable to
cool down, as the power supply
was interrupted.
- Too high air outlet temperature
because of incorrect air diffusion
in hose mode.
- Air cannot flow freely in or out.
8. Check whether the „Burner
fault“ pilot lamp has lit up on
the control panel. If so, reset
the automatic burner.
9. Turn the operating switch to
the „Ventilation“ setting.
If the inlet fan runs, it may be
necessary to seek the fault in
the burner area..
