*
Description of the Unit
The unit is directly fired with liquid gas in a gaseous
state. The unit works without an exhaust connection
and has been designed for automatic, universal and
smooth operation.
The unit is equipped with: an integrated power regula-
tion to gradually adjust the heating capacity, a robust
flame burner, an electrical solenoid valve, a quiet axial
fan requiring little maintenance, an ionisation monitoring
mechanism, electrical ignition, room thermostat socket
and connection cable with plug.
The unit meets the basic safety and health require-
ments of the relevant EU regulations.
The unit has been tested for conformance to EU proto-
types, it is DVGW-registered and safe and easy to oper-
ate.
Areas of Application
to dry new buildings
to provide localised heat for outdoor workplaces or
localised heat in production rooms and halls not sus-
ceptible to fire.
to permanently or temporarily heat closed and open
rooms that have sufficient fresh air intake
to de-ice machines, vehicles and non-flammable
stored goods and regulate the temperature of com-
ponents susceptible to frost.
For optimum unit operation, the device should not
be operated at an ambient temperature above 25 °C.
*
Unit Functionality
The air supply fan is put into operation by setting the op-
erating switch to “I. The burner also begins his program.
After a few seconds, the electrical solenoid valve opens
the gas supply to the burner. The liquid gas is supplied
to the burner pipe through a pressurised nozzle where
enough oxygen is added to meet the respective burner
capacity.
The resulting gas-air-mixture is ignited on the burner
head by an electric ignition spark. The ignition is auto-
matically ended once a proper flame is burning and the
burner has started to monitor the flame.
All unit functions are automatically performed and
safely monitored by the burners that are secured
against low voltage.
If the flame burns unevenly or goes out, the unit is
switched off by the burner. The malfunction light of the
burner lights up. The unit can only be restarted after the
burner has been manually released.
The safety temperature limiter (STB) interrupts the gas
supply and locks all functions if the unit overheats. The
STB can only be manually released after the unit has
cooled.
The min/max heat output can be gradually with the
“power regulation“ function during unit operation.

General Instructions
The unit may only be operated by persons who have
received proper training in its operation and how to
handle liquid gas.
When operating the unit, make sure to comply with
the relevant national/regional guidelines.
The unit may only be operated in rooms
– with sufficient air supply for combustion
– that are well-ventilated
– where the quantities of substances which can be
harmful when breathed in are admissible.
Good natural ventilation exists when, for example:
1. The room content in m³ equals 30 times the rated
heat output of all units in operation in the room
and natural ventilation is supplied through doors
and windows or
2. There are non-closable openings for air output
and intake close to the ceiling and floor whose
size in m² equals at least 0.003 times the rated
heat output in kW of all heating units in operation
in the room.
A standard unit connection pressure of 1.5 bar
(1500 mbar) of category I
countries.
is required for all EU
3B/P
Prior to operating the unit, the operating personnel
must check that the unit and its safety mechanisms
are functioning properly and that the safety mecha-
nisms have not been removed.
Any defects are to be reported to the supervisor im-
mediately.
The unit must be switched off if any defects are
found which endanger the safe operation of the unit!
The unit may be only serviced by authorised person-
nel; only original spare parts may be used.
Parts that wear out must be replaced on a regular
basis unless an authorised service person confirms
that the unit is functioning smoothly.
If the unit has been switched off by the temperature
limiter due to overheating, the reason the problem
occurred has to be identified and fixed.
If work is performed on the gas supply hose or if
the gas cylinder is replaced, all stop valves must
be closed and nothing which can potentially ignite
*
may be present in the immediate surroundings.
The connection pressure may not fall below or ex-
ceed the required value.
When longer hoses are used, the corresponding
pressure loss has to be taken into account.
Use only those parts, such as gas hoses, pressure
controller and mechanisms which protect lines and
hoses from breaking and safety mechanisms that
prevent gas leakage, that have been tested and are
suitable for the intended purpose.
The pressure controllers must have a fixed initial pres-
sure of 1500 mbar and must be equipped with a
mechanism that prevents the hose from breaking.
The unit may not be operated if the gas is in a liquid
state as it enters the burner.
At building sites, only hoses designed for use with
liquid gas may be used.
In accordance with regional regulations.
The length of the gas hose should not exceed 2 me-
tres.
Longer hoses may be used if safety regulations are
observed and the length of the hoses is kept as
short as possible.
Gas hoses must be protected against chemical,
thermal and mechanical damage.
If unit operation is unmonitored, hoses must be used
that protected against breakage.

Gas Supply
Connect the gas hose as follows:
1. Connect the pressure controller
to the gas cylinder(s).
Caution!
Left-handed thread!
*
2. Open cylinder(s) valve(s).
When gas is removed from sev-
eral gas cylinders simultane-
ously, all the valves have to be
opened.
3. Press the release button of the
hose protection mechanism after
opening the valve(s).
This must be done each time
the cylinders are replaced.
4. After installing and connecting
the units, check all gas connec-
tions to make sure they are
tight.
Soap solution, leak detection
spray etc.
Do not use open flames!
Important Information about Installation
When installing or removing the gas hose, make sure to
exert counterpressure on the unit’s gas connection nip-
ple using an open-end spanner SW 19 and remember-
ing that the thread is left-handed.
This process also applies to all other gas components,
including the pressure controller, hose protection device
(against breakage), etc.
Important Safety Instructions
The gas tanks may not be placed directly behind the
unit!
Never heat up or de-ice the gas tank using the hot
air coming out of the unit.
Danger of explosion.
Never place the gas tank on its side when the unit is
in operation.
Danger of explosion.
Important Information about Ice Formation on the
Gas Supply System
There is a danger that ice will form on the gas or pres-
sure tanks if the dimensions of the gas supply system
are insufficient. When the gas pressure falls, it is no
longer possible to ensure that gas is properly supplied
to the consumer system.
This can result in imperfect combustion or harmful ex-
haust fumes, or may cause the flame to go out.
The frost crystals may not be removed using an open
flame, burning embers or radiators.
The gas supply system is to be set up in accordance
with the unit’s connection value (see type plate), length
of operation and ambient temperature of the supply
tanks.
In general, we recommend that using a set of at least 3
cylinders to prevent heavy ice formation on the tanks.
The number of cylinders can be increased using a
multi-cylinder set (accessories) depending on the unit
capacity and the length of operation.
Assembly of Multi-Cylinder Set
