The unit may be operated only by those persons who
have been instructed regarding the unit’s operation
and the handling of liquid gas.
When using the unit make sure always to obser-
ve the guiding principles of the countries and
states concerned.
The 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 le-
ast 0.003 times the nominal heat load in kW of all the
units being operated in the room.
A uniform unit connection pressure of 0.3 bar (300
mbar) of category I3B/P is necessary for all countries
of the European Community.
The connection pressure may not fall below or
exceed the required value.
Make 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 cont-
rollers must have a firmly regulated initial pressure of
300 mbar and are to be equipped with a security de-
vice against hose breakage.
Hose pipes are to be protected generally against
chemical, thermal and mechanical damage.
The 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 ope-
ration is to be stopped!
The unit may be only maintained by trained persons
and only original spare parts may be used.
If the unit has been switched off by the temperature
limiter due to overheating, the reason for the fault
has to be detected and eliminated.

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 a-
gainst breakage) after having o-
pened the valve(s).
This has also to be done after
each replacement of bottles.
After the installation and
connection of the units all
the gas bearing connecti-
ons have to be checked
with soap solution, leakage
detecting spray etc. to
make sure that they are
tight.
Do not use open flames!
Hint!
Insufficiently dimensioned supply plants can cause i-
cing of the pressure gas or pressure reservoirs. When
the gas pressure falls a proper gas supply to the consu-
mer points can no longer be ensured in many cases.
This will result in imperfect combustion, harmful waste
gases or extinction of the flame. Therefore the supply
plant is to be dimensioned in such a way as to ensure
that problems of this kind cannot be caused.
The cristalline white frost may not be removed by open
fire, glowing objects or radiators. Sufficient gas supply
to the consumer points can be ensured by using an e-
vaporator.
Sufficient gas supply is to be ensured according to the
unit power rating (see identification plate), service life
and ambient temperature of the supply tanks.
In principle, we recommend that you use a set of at le-
ast 3 cylinders to avoid intensive icing of the reservoirs.
The number of cylinders can be increased by using a
set of several cylinders (accessories), depending on
the unit capacity and the service life.
1) Unscrew gas hose
Turn union nut clockwise
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.
This procedure also refers to all further gas compo-
nents, such as pressure controller, hose security device
(protection against breakage), etc.
When any work is carried out on the gas supply
line and when the gas cylinder is replaced, all
stop valves must be closed and there may be
no ignition sources in the direct surroundings.

2) Fasten gas hose
Turn union nut anti-clockwise

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 re-
garding the handlings concerned.
The persons charged with the operation of the units ha-
ve to check the units before starting work to detect ob-
vious defects on the operating and safety elements and
to make sure that the safety devices have not been re-
moved.
Make sure to draw the operators‘ attention to possible
dangers during the handling of liquid gas.
A constant unit connection pressure of
0.3 bar (300 mbar) must be ensured, also
during continuous operation.

Connect pressure controller to
the gas bottle(s).
Attention!
left-handed thread!

Install only in well ventilated rooms, not in rooms which people will be using for longer periods! 

Press down pin (2) of thermoelectric
gas valve (safety pilot).
Put the operating switch into po-
sition "O"(= Off) and plug the
mains into an appropriate mains
socket with fault current safety
switch (230V/1~ 50 Hz).
Close all the bottle valves.
Let flame burn out.
The fan should still run for a few
seconds to exhaust the accumu-
lated heat.
Put operating switch (1) into “0”
position (= off) and unplug mains
plug from the mains socket.

Important Hints!
Make sure that the supply air can be freely sucked
and the heated air can be blown off without prob-
lems.
The suction and blower apertures of the unit may
not be narrowed or equipped with hoses or condu-
its.
Make sure to keep the safety distance from com-
bustible and inflammable materials and to observe
the local fire protection codes.
After approx. 2 or 3 sec. the piezo
igniter (3) is to be actuated (possibly
several times) with the pin (2) still
held down, until a formation of flames
has occured.
Put the operating switch into "I"
position (= heating operation)
The supply air fan starts.
After the formation of flames still hold down the pin (2)
for approx. 10 - 15 seconds, until the thermoelectric
flame monitoring has started.
Do not release the pin before this.
If the flame is extinguished after the pin has been re-
leased, repeat the ignition procedure after having wai-
ted for approx. 1 minute. Then keep the pin pressed
down a little longer.
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 u-
nit is operating (gas leakage in the liquid phase).
Assembly of Multi-bottle Set
To avoid intensive icing of the gas bottle during a lon-
ger 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!
The electric connection of the unit is to be carried
out according to the VDE 0100 regulations
§ 55, via a special supply point with fault current
safety switch.

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.
If any faults are stated the supervisor is to be informed.
If the faults affect the unit’s operational reliability, ope-
ration is to be stopped!
Regular maintenance and care, at least after each
heating period is the basic condition for a long servi-
ce life and a faultless operation of the unit.
Make 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).
Do not use sharp or solvent-containing cleaning a-
gents.
Check suction and blowing out lattice regularly to
see whether it is dirty and clean it, when necessary.
Check 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.
Check gas hoses and sealings to see whether they
are damaged and replace when necessary.
Clean gas burner and gas nozzle regularly.
Clean baffle plate regularly.
Check ignition electrode and set when necessary.
Check thermocouple and clean when necessary
The bi-metal spring may neither be damaged nor
bent in or order not to affect the function of the tem-
perature-limiter!
