Safety hints
Please make sure that the relevant local building
and fire protection codes as well as the regulations
of the employer's liability insurance associations
are observed when the units are used.
l The units may be operated only by persons who
have been trained in this field.
l The units are to be installed and operated in such a
way as to ensure that the personnel is not jeopardi zed by waste gases and radiation heat and that no
fire can break out.
l The units may be installed and operated in rooms
only if sufficient air can be fed to the units to ensure
perfect burning.
l Fuel may be supplied only based on the VGB 21
regulations (use of liquid gas).
l Make sure that mobile liquid gas holders are instal led in a stable way and in an upright position.
l During the unit's operation liquid gas holders are not
to be used in a lying position;
(gas leakage in the liquid phase!).
l The units may be operated only in well aerated rooms.
The permanent stay of persons in the rooms where
the units are installed is prohibited. Appropriate
prohibition signs are to be fitted at the entrances.
l The units may be installed only on a non-combusti ble base.
l The units may not be installed and operated in en vironments which are endangered by fire and explo sions.
l A safety zone of 1.5 m around the unit, as well as a
minimum distance of 3 m from the unit's blower
aperture is to be maintained, even in the case of non
combustible objects.
l The blower aperture of the unit may not be narrowed
or equipped with hoses or conduits.
l Never place foreign matters/objects into the unit.
l The air suction grid must be free from dirt and loose
objects.
l The units may not be exposed to direct water jets.
l All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
l When maintenance work and repairs are carried out
the gas supply is to be cut off and the mains plug to
be pulled out of the mains socket.
l Safety devices may be neither bridged nor blocked!
Gas supply
The gas supply/operation of the unit may be carried out
only based on the safety regulations VBG 21 as well as
on the applicable local building and fire protection codes.
The units have been conceived for a constant supply
pressure of 1.5 bar (liquid gas according to DIN 51622
Kat I
A higher or lower supply pressure is inadmissible. When
longer hoses or conduits are used the resulting loss of
pressure is to be taken into account. Only tested components, such as gas hose, pressure controller, hose
shearing pin or gas leakage safety device, which are suitable for the intended purpose are to be used. Only pressure controllers with firmly set outlet pressure are admissible.
The units may be operated only based on the gas phase.
G
, I3+).
3B/P
A constant gas supply pressure of 1.5 bar
(1500 mbar) is to be ensured, even under
continuous duty!
Connect the pressure controller to
gas cylinder(s) or supply plant.
Attention!
left-handed thread!
G
Open the cylinder valve(s) or stop
valve of supply line. If gas is taken
out of several gas cylinders simultaneously all the valves are to be
opened.
Press the unlocking button of hose
shearing pin after having opened
the valve(s).
This must also be done each time
when having replaced the cylinders.
When the units have been installed
and connected, all gas bearing connections are to be checked to ensure that they are tight (soap solution,
leakage detection spray).

Important Installation Hint
When the gas hose is installed or removed make sure
to counteract at the gas connection nipple of the unit
(according to DIN 4815, part 2) by means of an openended spanner SW 19, whereby the left-handed thread
is to be taken into account.
Multi - cylinder Set
All cylinder valves are to be opened to ensure regular
gas tapping.
gas hose to unit
hose shearing pin
Loosen gas hose Fasten gas hose
Turn the union nut Turn the union nut
clockwise anticlockwise
This procedure is to be carried out also for all further
gas components, such as pressure controller, hose
shearing pin, etc.
When any work is carried out on the gas supply
line and when the gas cylinder is replaced, all
G
stop valves must be closed and there may be
no ignition sources in the direct surroundings.
Hint!
Insufficiently dimensioned supply plants can cause icing
of the pressure gas or pressure reservoirs.
When the gas pressure falls, a proper gas supply to the
consumer 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 evaporator.
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
least 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.
pressure controller
HD-hose 0.4 m
T-connection
Important!
The pressure gas tanks are to be installed laterally
behind the unit. The tanks may never be heated and
defrosted, respectively by the unit's hot air current
(danger of explosion!)
Cylinders with liquid gas may never be used in a lying
position when the unit is in operation (gas leakage in the
liquid phase).
Tank Gas Plants
When the units are connected to tank gas plants, make
sure that the pipes are properly dimensioned according
to the conduit length.
We recommend that a permanently set pressure
controller with an outlet pressure of 1.5 bar and an
appropriate gas throughput (please refer to unit type
plate) is installed directly beside the unit, as well as a
certified stop valve which has been adapted to the
admission pressure concerned, to ensure a perfect
function of the unit.
It has proven that the installation of a gas filter in front of
the control and safety devices of the units is absolutely
necessary (please also refer to DIN 4788 and TRF 88,
section 5), to avoid operating troubles of the control and
safety devices of the unit which can be caused by
harmful substances such as rust and dust from the gas
supply line (or tank).
Clean gas supply line thoroughly before starting the unit for the first time!

Starting
A properly trained person is to be charged with the
operation of the units, as well as with the control of the
holders and the cylinder stock.
The operator's attention is to be drawn to any
dangers in connection with the use of liquid gas.
Put the operating switch into "0" position (= Off) and plug the mains into
an appropriate mains socket
(230V/ 1~ 50 Hz).
Setting/Regulation of Heating Capacity
Set desired heating capacity at the continuous "PowerRegulation".
Turn to the left:
larger heating capacity
Turn to the right:
smaller heating capacity
The setting can also be continuously changed during the
unit operation.
Ventilation
The electric connection of the units is to be carried out according to the VDE 0100 regulations
§ 55, via a special supply point with fault current safety switch.
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
igniter is to be actuated (possibly
several times) with the pin still
held down, until a formation of flames has occured.
Put the operating switch into position "II".
In this position only the supply air fan
runs and the unit can be used for air circulation.
Heating is not possible!
Important Hint!
Make sure that the supply air can be freely sucked
and the heated air can be blown off without problems.
Make sure to keep the safety distance from combustible and inflammable materials and to observe the
local fire protection codes.
Shut-down
Close all the cylinder valves and
stop valves of the supply line.
After the formation of flames still hold down the pin for
approx. 10 seconds, until the thermoelectric flamemonitoring has started.
Do not release the pin before this.
If the flame is extinguished after the pin has been released, repeat the ignition procedure after having waited for approx. 1 minute. Then keep the pin pressed
down a little longer.
Install only in well aerated rooms, but not in living areas and recreation rooms!
G

Let the flame burn out.
Put the operating switch into "0"
position (= Off) and unplug the
mains plug from mains socket.
G
Unit function
When the unit has been switched on (operating switch in
position "I" = heating operation), the supply air fan is
started and the electric solenoid opens. However, gas
supply to the burner is still blocked. Gas supply to the
burner is released only after having pressed on the pin
of the thermoelectric gas valve (safety pilot).
The liquid gas is supplied by means of a nozzle under
pressure to the burner pipe, where it is enriched with an
adequate quantity of oxygen which has been adapted to
the burner capacity concerned.
The generated gas-air-mixture is ignited at the burner
head by an electric ignition spark. The spark is generated by the manual actuation of the piezo igniter. The
thermoelectric control of the flame is started by heating
the thermocouple. The pin of the safety pilot is to be released.
Gas supply is interrupted in case of operating troubles or
when the flame goes out. However, the supply air fan
continues working. The unit has to be restarted.
In the case of overheating, the gas supply is interrupted
by a safety thermostat (STB) which blocks all the functions of the unit. A manual release of the STB can be carried out only after the unit has cooled down.
During the operation of the unit the min/max heating capacity can be regulated continuously by means of the
built-in "Power Regulation".
Interference elimination
The unit is equipped with a safety thermostat (STB)
which, in the case of overheating, interrupts gas supply
and locks the electric devices of the unit. Any functions
of the unit are switched off.
If the safety thermostat has been released, the reason
for the trouble is to be localized and to be eliminated.
Release is to be carried out after having screwed off the
protecting cap and after having pressed down the key
"STB-RESET".

The "RESET" position can only be set when the feeler
has cooled to a temperature below approx. 90°C.
In the chapter "Troubleshooting Instructions" you
will find a detailed chart regarding the elimination of
faults.

Maintenance
The units are to be checked by an expert as to their
perfect operation, when it is necessary and in accordance with the terms of use, but at least every two years.
The result of this check is to be recorded in a test certificate, which is to be kept safely until the next check is
carried out, and which can be presented to authorized
persons at any time.
The persons charged with the operation of the units
have to check these before starting the operation as to
visual faults at the control and safety devices, and they
have to make sure that the protective devices have been fitted.
In the case of faults the supervisor is to be informed.
If those faults endanger the operational reliability of the
unit, its operation is to be stopped!
l The units are to be maintained regularly, but at least
after each heating period to ensure their trouble-free
operation and a long service life.
l The units are to be kept free from dust and other dirt,
and it is to be cleaned with a dry or humid cloth
(do not use water jets for cleaning).
l Do not use any aggressive cleaning agents or
cleaners containing solvents.
l The suction opening for combustion air, as well as
the injector fitted behind it and the gas nozzle are
to be checked regularly to ensure that they are free
from dirt.
l Clean gas burner and gas nozzle regularly.
l Clean diaphragm plate regularly.
l The suction and blow off grid are to be checked
regularly to ensure that they are free from dirt,
otherwise they are to be cleaned.
Removal and Cleaning of the Gas Burner
l Remove blow-off protective grid and outside casing,
as well as the inspection cover at the lower side of
the unit.
l Loosen clamping screw of the nozzle holding device.
l Remove iginition cable from ignition electrode
(Take care of cap nut and lock washer).
l Screw capillary tube off the safety pilot.
l Release clamping screw of electrode holder and
