Cleaning and Maintenance
Switch the unit off, unplug it and give the heater time to cool off before you clean it
or perform maintenance.
Keep the unit clean (particularly the grills and the ventilator blades) and remove
dust regularly. You can clean the housing with a damp cloth. Never use aggressive,
corrosive or abrasive cleaning agents.
You can carefully try to remove dust and other dirt in the unit with a brush, vacuum
it out or blow it off (carefully) with a compressor.
Check the incineration after the heater is ignited. The normal flame is blue and not
outside of the unit. The flame must be stable and the entire flame circle must be
uniform in shape. If that is not the case, there is something wrong with the
incineration. Contact your service department.
Regularly check the gas hose and its screw connections. If the hose is damaged
(kinked, burst or worn out, shows signs of burns or anything), this must be
replaced immediately. Even without visible damage, the hose must be replaced at
least every 3 or 4 years (see the printing on the hose). Only use an approved gas
hose.
If the gas tap on the gas bottle falters and the gas supply cannot be turned off
normally, first press the power regular to (O) and unplug the unit. The gas valve
will now block the gas supply and the heater will shut off. Allow the unit to cool off,
but don't disconnect the gas hose! Take the gas bottle and the connected device to
your gas supplier to have the problem solved. This defect is not in your unit.
If you think you won't use the device for a long time, you should disconnect the gas
supply hose from the unit and place the protective cap on the opening. Put the unit
in the original packaging (or another dust-free box or bag) and keep it in a cool,
dry place outside the reach of children. Before you use the device again, you must
check whether the ventilator is working properly and no flammable materials are
still next to/in/on the heater. Also perform a gas leakage test.
Repairs must only be performed by qualified people. Never open the heater
yourself! Make sure that only original parts are used; that definitely applies to the
gas hose and the pressure regulator!
The heater must be inspected at least once a year by a qualified person.
