well as the rules of the trade co-operative association.
Additionally please note the following safety instructions.
◊
The unit may be operated only by those persons who
have been instructed accordingly.
◊
The unit is to be installed and operated in such a
way as to ensure that the employees are not endan-
gered by waste gases and radiation heat and that no
fire can break out.
◊
The unit may only be installed and operated in
rooms, when the air rate fed to the unit is sufficient
for combustion.
◊
Make sure to install mobile liquid gas reservoir on a
solid ground and in a vertical position.
◊
Liquid gas reservoir may never be used in a lying po-
sition while the unit is operating.
Explosion hazard: Gas exit in the liquid phase from
the gas nozzle.
◊
The unit may be operated only in well aerated rooms.
◊
Persons may not stay permanently in the room
where the unit has been installed.
Relevant prohibition signs are to be fastened to the
entrances.
◊
The unit is to be installed and operated on a solid
non combustible ground.
◊
It is to be ensured that no combustible objects/
materials can be sucked in.
◊
The unit may not be installed or operated in inflam-
mable and explosive surroundings.
◊
A safety zone of 1.5 m around the unit and a mini-
mum distance of 3 m at the unit’s exhaust opening
are to be observed, even regarding non combustible
objects.
◊
The unit’s exhaust opening may not be reduced or
equipped with hoses or pipings.
◊
Make sure not to introduce foreign matters into the
unit.
◊
The air suction grille is always to be kept free from
dirt and loose objects.
◊
The units may not be exposed to direct water jets.
◊
All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
◊
Make sure to cut off the gas supply and to pull the
mains plug out of the mains socket when mainte-
nance and repairs are carried out.
Safety devices may be neither bridged nor
blocked.
Description of Device
The unit is a mobile, liquid gas fired heater without a
combustion chamber and with a fan for transporting hot
air.
The unit works without an exhaust system and is only
suitable for industrial purpose.
The unit is directly heated and are suitable for a all-
purpose and simple application.
The unit are equipped with noiseless maintenance-free
axial fan, durable gas burner, electromagnetic valve,
piezo electric ignition, ignition protection with thermoe-
lectric flame monitoring and connecting cable with plug.
The unit is in accordance with the basic safety and
health requirements of the relevant EU – regulation.
Areas of Application
◊
For drying new buildings.
◊
Spot heating of working places outside or in open, fire-
proof halls and production places.
◊
Permanent or temporary heating of rooms with suffi-
cient fresh air intake.
◊
For defrosting of machines, vehicles and non flam-
mable storage goods;
◊
for tempering frost-endangered parts.
Working of Device
When the unit has been switched on (operating switch
in position "I" = heating operation), the supply air fan is
started and the electromagnetic valve opens. However,
the gas supply to the burner is still blocked.
The gas supply to the burner is released only after hav-
ing 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 en-
riched 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 gener-
ated by the manual actuation of the piezo electric ig-
niter.
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.
The temperature limiter interrupts the gas intake when
the unit is overheating. The automatic release of the
temperature limiter occures after the unit has cooled
down. A restart of the unit is necessary.
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.
