- release hose break protection resp. replace it
5. no ignition spark - set ignition electrode
- check ignition cable
- check porcelain insulation of ignition electrode
6. Air suction grille is dirty - clean air suction grille
7. unit is shut down by safety temperature limiter (STB) - check air suction and blow-out grille and clean if necessary
- check fresh air supply
- release safety thermostat (STB - Reset)
8. safety pilot does not open or does not lock - replace safety pilot
9. piezo igniter is defective - replace piezo igniter
10. thermocouple is not getting warm enough - check position of thermocouple and adjust according to setting in-
structions
11. loose or dirty connection between safety pilot and thermocouple - check connection and clean if necessary
12. pressure controller defective or improper pressure controller at-
tached or hose breakage protection is blocked
- attach original pressure controller
- release hose breakage protection or replace it
13 ice has formed on the gas cylinder(s) due to low temperatures
and too much gas output
- replace empty gas cylinder(s) and connect 2-3 cylinders using multi
cylinder set (Ref-No. 1014050)
