Troubleshooting; Volatile Lock Outs; Temporary Errors - Winterwarm DXE80 Installation Manual

NOTICE The injectors have a stamp that corresponds
to the diameter of the injector. For example, 130 means
1.30mm and 210 means 2.10mm.
9. Apply the sealing paste from the conversion kit on
the threads of the injectors.
CAUTION! Avoid paste from getting into the injectors.
10. Insert the new gas injectors.
11. Reattach the burner tube to the burner unit.

9. Troubleshooting

If the air heater malfunctions, first check if the problem is
caused by external circumstances (e.g. no supply power).
If the problem is not caused by external circumstances,
use the tables and instructions in this chapter to fix the air
heater.
NOTICE Please remember the built in waiting times of
the air heater; the signals of the LED's and the code on the
display. Do not react too soon.
