General Hints
²The unit may be operated only by those persons who
have been instructed regarding the unit’s operation
and the handling of liquid gas.
²When using the unit make sure always to obser-
ve the guiding principles of the countries and
states concerned.
²The unit may only be operated in rooms when
–the air rate fed to the unit is sufficient for com-
bustion and
–the rooms are well ventilated and deventilated
and
–the percentage of the substances which are
injurious to health in the breathed in air has
no inadmissible concentration.
A good and natural ventilation and deventilation
is given if e.g. the room volume in m³ corresponds to
at least 30 times the nominal heat load in kW of all
the units being operated in the room, and if a natural
air exchange through doors and windows is ensured,
or if there are permanently open ventilation possibili-
ties for ingoing and outgoing air near the ceiling and
the floor, of which the size in m² corresponds to at
least 0.003 times the nominal heat load in kW of all
the units being operated in the room.
²A uniform unit connection pressure of 1.5 bar (1500
mbar) of the category I 3B/P is necessary for all the
countries of the European Community.
The connection pressure may not fall below or
exceed the required value.
²Make sure to use exclusively components, such as
gas hose, pressure controller and hose security devi-
ces (protection against breakage) or safety devices
against gas leakage, that have been tested and are
suitable for the intended purpose. The pressure con-
trollers must have a firmly regulated initial pressure
of 1500 mbar and are to be equipped with a security
device against hose breakage.
²Hose pipes are to be protected generally against
chemical, thermal and mechanical damage.
²The persons charged with the operation of the unit
have to check it prior to starting work to make sure
that there are no visible defects. If there are defects
which affect the unit’s operational reliability, its opera-
tion is to be stopped!
²The unit may be only maintained by trained persons
and only original spare parts may be used.
²If the unit has been switched off by the temperature
limiter due to overheating, the reason for the fault
has to be detected and eliminated.

Starting
Make sure to charge a person with the operation of the
unit and with the supervision of the reservoirs and of the
bottle stock who has been instructed sufficiently regar-
ding the handlings concerned.
Make sure to draw the operators‘ attention to possible
dangers during the handling of liquid gas.
Connect pressure controller to the
gas bottle(s).
Attention –left-handed thread!
Open bottle valve(s).
When gas is taken out of several
gas bottles simultaneously, all the
valves have to be opened.
Press release button of the hose
security device (protection against
breakage) after having opened the
valve(s).
This has also to be done after each
replacement of bottles.
After the installation and connec-
tion of the units all the gas bearing
connections have to be checked
with soap solution, leakage detec-
ting spray etc. to make sure that
they are tight.
Do not use open flames!
1) Unscrew gas hose
Turn union nut clockwise
2) Fasten gas hose
Turn union nut anti-clockwise
This procedure also refers to all
further gas components, such as
pressure controller, hose security
device (protection against break-
age), etc.
Important Installation Hint
When installing or removing the gas hose make sure to
exert a counterpressure on the gas connection
nipple of the unit using an open-end spanner SW 19
and observing the left-handed thread.
Aconstant unit connection pressure of 1.5 bar
(1500 mbar) must be ensured, also during con-
tinuous operation.

The setting can also be continuously adjusted when the
unit is operating.
Setting/Regulating the Heating Capacity
Set desired heating capacity by means of the
continuously adjustable “power regulation”.
Turn to the left:
increased heating capacity
Turn to the right:
reduced heating capacity
Put the operating switch into position
"O" (= Off) and plug the mains into an
appropriate mains socket with fault cur-
rent safety switch (230V/1~ 50 Hz)
Put the operating switch into "I" position
(= heating operation)
The supply air fan starts.
Press down pin of thermoelectric gas
valve (safety pilot).
After approx. 2 or 3 sec. the piezo igni-
ter is to be actuated (possibly several
times) with the pin still held down, until a
formation of flames has occured.
Heating Operation
After the formation of flames still hold down the pin for
approx. 10 seconds, until the thermoelectric flame mo-
nitoring has started.
Do not release the pin before this.
If the flame is extinguished after the pin has been relea-
sed, repeat the ignition procedure after having waited
for approx. 1 minute. Then keep the pin pressed down
a little longer.
Put the operating switch into position "II".
In this position only the supply air fan
runs and the unit can be used for air cir-
culation.
Heating is not possible!
Ventilation

5
Close all the bottle valves.
Let flame burn out.
The fan should still run for a few
seconds to exhaust the accumulated
heat.
Putting out of Service
Put operating switch into “0” position (=
off) and unplug mains plug from the
mains socket.
Important!
Make sure to place gas reservoir only laterally behind
the unit! Never heat up or defrost gas reservoir through
the unit’s hot air current (danger of explosion!).
Never use gas reservoir in a lying position when the unit
is operating (gas leakage in the liquid phase).
Assembly of Multi-bottle Set
To avoid intensive icing of the gas bottle during a longer
operation of the unit, we recommend that you use a
bottle battery consisting of at least 3 bottles. All bottle
valves must be open to ensure regular gas supply!

Important Hints
“RESETTING” is not possible before the sensor has
cooled down below approx. 90 °C.
You will find a detailed chart for the fault elimina-
tion in chapter “Action in the case of faults”.
The safety temperature limiter (STB) interrupts gas
supply in the case of overheating and the unit is locked
on the electric side. Any unit function is switched off.
When the safety temperature limiter has released, the
reason for the fault is to be detected and to be elimina-
ted first. Unlocking is carried out when the protective
cap has been unscrewed by pressing the key “STB-
RESET“.
-remove protective cap (1)
-press key (2)
-refit protective cap (1)
Maintenance
Depending on the operation conditions the units are to
be tested by an expert when necessary, but at least re-
gularly every two years, to ensure their safe operation.
The test result is to be recorded in a test certificate
which is to be safely kept until the next test so that it
can be presented to the authorized persons for control
purposes at any time.
The persons charged with the operation of the units
have to check the units before starting work to detect
obvious defects on the operating and safety elements
and to make sure that the safety devices have not been
removed.
If any faults are stated the supervisor is to be informed.
If the faults affect the unit’s operational reliability, opera-
tion is to be stopped!
lRegular maintenance and care, at least after each
heating period is the basic condition for a long ser-
vice life and a faultless operation of the unit.
lMake sure to keep the unit free from dust and other
deposits and to clean it only with a dry or humid cloth
(do not use water jet).
lDo not use sharp or solvent-containing cleaning
agents.
lCheck the suction opening for combustion air as well
as the injector fitted behind it and the gas nozzle re-
gularly to make sure that they are not dirty.
lClean gas burner and gas nozzle regularly.
lClean baffle plate regularly.
lCheck suction and blowing out lattice regularly to see
whether it is dirty and clean it, when necessary.
When the unit is being maintained, set or repai-
red, the gas supply has to be cut off and the
mains plug has to be unplugged from the mains
socket!
Setting and maintenance work is to be carried
out only by authorized specialists!
