Description of the Unit
The unit is a mobile, liquid gas-fired heater with a fan for
transporting hot air. It does not have a heat-exchanger.
The unit works without an exhaust system and is only
suitable for industrial purposes. The unit is a direct-fired
device which has been designed for universal and
smooth operation.
The unit is equipped with an integrated “power regula-
tion“ function for gradual control of heat output, as well
as with a durable flame burner, an electromagnetic
valve, a piezo electric ignition, a safety pilot with ther-
moelectric flame monitoring, a connecting cable with
plug and finally a quiet axial fan which requires little
maintenance.
The unit meets the basic safety and health require-
ments found in the relevant EU regulations.
Areas of Application
The unit can be used, for example:
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.
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 se-
curely 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 main-
tained 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 pro-
tected 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
When the unit is switched on (operating switch set to "I"
= heating mode), the air supply fan starts and the elec-
tromagnetic valve opens. However, the gas supply to
the burner is still closed off.
The gas supply to the burner is released by pressing
the pin of the thermoelectric gas valve (safety pilot).
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 spark is generated
by manually triggering the piezo electric igniter.
Thermoelectric flame monitoring is started by heating
the thermocouple. The safety pilot pin must now be re-
leased. If there are operational problems or the flame
goes out, the gas supply is interrupted. However, the
supply air fan continues running.
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.
For optimum unit operation, the device should not
be operated at an ambient temperature above 25 °C. *
