Troubleshooting instructions
Make sure that the gas supply has been closed and the mains plug has been taken
out of the mains socket before carrying out any work regarding the unit!
Setting and maintenance is to be carried out only by authorized experts!
cause: remedy:
1) no electrical connection - plug the mains into an appropriate mains socket (230V/1~ 50Hz)
2) fan motor is overcharged (fan blows irregularly or is blocked) - check fan motor, fan blade and clutch plate and replace if necessary.
3) operating switch defect - close gas supply, unplug the mains and replace defect operating
switch
4) no gas pressure on solenoid valve - check gas supply
- check contents of gas cylinders
- check gas hose(s) for damage
- 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 impurified - clean air-suction grille
7) unit is shut down by safety thermostat (STB) - check air-suction and blow-out grille
- check fresh air supply
- release safety thermostat (STB - Reset)
8) gas regulation fefect resp. impurified - replace gas regulation
9) safety pilot does not open (resp. does not lock) - replace safety pilot
10) piezo igniter defect - replace piezo igniter
11) thermocouple is not getting warm enough - check position of thermocouple and adjust according to setting hints
12) loose or impurified connection between safety pilot
and termocouple - check connection and clean if necessary
13) pressure controller defect or false pressure controller mounted
resp. hose break protection is blocked - mount original pressure controller
- release hose break protection resp. replace it
14) gas cylinder(s) iced over due to low temperatures
and too high gastaking - replace empty gas cylinder(s) and connect 2-3 cylinders using multi
cylinder set (EDV-No. 1014050)
15) solenoid valve does not open - close gas supply
- let flame burn out
- put operating switch in position „0” and unplug the mains
- replace solenoid valve
16) leak gas hose(s) - find leakage by foam forming mediums
- eleminate leakage
trouble: cause:
– unit doesn’t start 1 – 2 – 3 – 4 – 7
– unit stops during operation 2 – 4 – 7 – 13 – 14
– fan blows, but gas supply is blocked
resp. no ignition 4 – 5 – 9 – 10 – 13
– flame goes out after having released the pin of
thermoelectric gas valve 9 – 11 – 12
– gas supply is blocked, resp. flame goes out 4 – 6 – 7 –11 – 12 – 13 – 14
– fuel consumption is too high 13 – 16
– unit can’t be shut down 3 – 15
– heating capacity drops during continuous operation 13
– heating capacity can’t be regulated 8
