The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
The fan does not start:
•
Check whether the device is switched on. The on/off
switch (2) should be set to
I
.
•
Check the power connection.
•
Check the power cable and mains plug for damages.
•
Check the on-site fusing.
•
Check whether the overheating protection has tripped, see
chapter Safety.
•
The fan motor might be defective. Have a defective fan
motor replaced by a specialist electrical company.
•
There might be a fault in the circuitry. Have the electrical
system checked by a specialist electrical company.
The fan is running, but the gas fails to ignite:
•
Check whether the device is switched on.
•
Check whether the connection line is properly connected.
•
Make sure that the valve at the gas cylinder is open.
•
Perhaps the gas cylinder is empty and needs to be
replaced.
•
The ignition electrode may be dirty or positioned
incorrectly. Have a specialist electrical company check the
ignition electrode.
The fan is running, the gas is ignited, but the flame dies
after a little while:
•
Check whether the gas hose is properly connected.
•
Perhaps the gas cylinder is empty and needs to be
replaced.
•
There might be a defect at the sensors or another part of
the circuitry. Have the electrical system checked by a
specialist electrical company.
The flame goes out during operation:
•
Check whether the overheating protection has tripped, see
chapter Safety.
•
Check whether the flame failure protection has tripped,
see chapter Safety.
•
Perhaps the gas cylinder is empty and needs to be
replaced.
•
The pressure reducer might be defective causing an
excessive gas supply. Replace the pressure reducer.
•
Insufficient gas supply due to icing on the gas cylinder.
Perhaps use a gas cylinder with a higher output rate, see
gas consumption in the Technical data chapter.
•
The supplied amount of combustion air might be
insufficient. Check the air inlet for obstructions and
whether the fan operates properly. If there is a problem
with the fan, have it checked by a specialist electrical
company.
The flame is too high:
•
Too much gas is emitted. The pressure reducer might be
defective and needs to be replaced.
The device is loud or vibrates:
•
Check whether the device is set up in a stable and upright
position.
Note
Wait for at least 3 minutes after maintenance and
repair work. Only then switch the device back on.
Your device still does not operate correctly after these
checks?
Please contact the customer service. If necessary, bring the
device to an authorized specialist electrical company or to
Trotec for repair.
