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.
Safety Instructions
Make sure to observe relevant local building and fire
protection codes and abide by professional association
regulations when the unit is in operation.
Please also observe the following.
The unit may only be operated by persons who have
received proper training in its operation.
The units must be installed and operated in such a
way that people are not exposed to radiant heat and
fires cannot occur.
The units may only be installed and operated in
closed rooms where the units have an adequate air
supply for combustion.
The portable liquid gas tanks must be set up securely
in an upright position.
During unit operation, the portable liquid gas tanks
may never be used while they are lying on their sides.
Danger of explosion: liquid gas may leak out of the
gas nozzle.
The unit may only be operated in well-ventilated
rooms.
Persons may not remain in the room where the unit
has been installed for longer periods of time.
Warning signs must be placed at the entrances.
The unit may only be set up and operated on a non-
flammable surface.
Make sure that no flammable objects/materials can
be sucked in to the unit.
The unit may not be set up or operated in surround-
ings susceptible to fire or explosions.
A safe distance off 1.5 m must be maintained around
the unit; a distance of 3 m must be maintained from
its exhaust opening, even for non-flammable objects.
The unit’s exhaust opening may not be reduced in
size or equipped with hoses or pipes.
Never insert foreign objects into the unit.
The air suction grille must always be kept free of dirt
and loose objects.
Do not expose the unit to a direct stream of water.
All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
Before performing any maintenance or repair work,
make sure to unplug the unit from the power supply
and disconnect it from the fuel supply.
*
Do not bypass or block safety mechanisms while
the unit is in operation.
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.
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.
