BURNER START-UP CYCLE
FAILURE DETECTION ON HEATING DEVICE
NORMAL OPERATION
The plug fitted in the panel is placed in the position
corresponding to “Resistance ON”
(see
drawing on the right).
When the remote control closes, the LED lights up
and, after about two minutes, the burner starts up.
BURNER DOES NOT OPERATE
1) If the LED is OFF, the heating resistance placed
in the nozzle-holder is off.
2) If the LED is ON and nevertheless the burner
does not run, place the plug in the position cor-
responding to “Resistance OFF”
(see
drawing on the right).
If the motor runs, the delaying device inside the
control box is out of order.
3) If the motor does not run, it means that the fail-
ure is neither in the panel nor in the resistance,
but elsewhere.
