REMKO PG-T (S-Line) SERIES
Unit description
The units are mobile fan-assisted
air heaters (WLE) directly fired
with liquid gas, without a heat
exchanger.
The units operate without an
exhaust gas connection and
are designed exclusively for
commercial use.
The units are equipped with
integrated power regulation
for the stepless control of the
heating capacity, quiet and low-
maintenance axial fans, robust
gas burners with thermal flame
monitoring, electric solenoid
valves, electric ignition, room
thermostat socket and mains cable
with earthed safety plug.
The units conform to the
fundamental health and safety
requirements of the appropriate
EU stipulations, and are simple to
operate.
The units are EC type-tested,
DVGW-registered and approved
for EU countries.
The units may be used among
other things for the following:
■ Drying newly completed
buildings
■ Spot heating of outdoor
workplaces
■ Spot heating workplaces
in open, non-flammable
manufacturing facilities and
halls
■ Temporarily heating enclosed
spaces with a sufficient fresh air
supply
■ De-icing machines, vehicles and
non-combustible warehoused
goods
■ Maintaining the temperature of
frost-sensitive parts
Operating sequence
Moving the operating switch
to the “I” position puts the
supply air fan into operation and
the program sequence for the
automatic burner is started.
After a few seconds, the electric
solenoid valve opens the gas
supply to the burner. The liquid
gas is transported through a nozzle
under pressure into the mixing
tube. Here, the gas is enriched
with a quantity of oxygen aligned
with the unit output.
The gas/air mixture is ignited
at the burner head by an
electric ignition spark. Ignition is
automatically ended as soon as
a flawless flame burns, and the
automatic burner has taken over
the flame monitoring.
Regulation of the min/max heating
capacity can be implemented on a
stepless basis during unit operation
on the integrated “power
regulation”.
Monitoring the units
It is possible to safely monitor all
functions with the safety devices
of the units.
In the event of irregularities or if
the flame is extinguished, the units
are switched off and interlocked.
Safety temperature limiter (STB)
The units are equipped with a
safety temperature limiter (STB),
which interrupts the gas supply in
case of overheating and electrically
interlocks the unit.
A manual reset of the STB can only
be implemented after the units
have cooled down.
The STB is reset by actuating the
reset key 2.
1. Unscrew the protective cap 1.
2. Push in key 2.
3. Screw the protective cap 1 back
on again.
Automatic burner
In the event of irregularities or
if the flame is extinguished, the
automatic burner switches off and
interlocks the units.
The unit's fault lamp will light up
in this case.
The automatic burner is unlocked
by pressing the malfunction
button.
The automatic burner can be
unlocked after a waiting time of
approx. 60 sec.
12
CAUTION
If the safety temperature
limiter has been triggered, the
cause of the malfunction must
be identified and rectified
before a reset is performed.
NOTE
Before resetting safety
equipment, the cause of the
malfunction must be identified
and rectified.

sufficient
The gas connection/unit operation
must take place exclusively on the
basis of the accident prevention
regulation DGUV 79, “Use
of liquid gas”, as well as the
respective local construction and
fire prevention regulations.
The fuel supply must be installed
in accordance with DIN 4755 for
oil-fired warm air heaters, DVGW
Code of Practice G 600 for gas-
fired warm air heaters and TRF for
liquid gas.
The units are operated with liquid
gas in accordance with DIN 51622.
They require a constant unit
connection pressure of 1.5 bar.
It is prohibited to exceed or
undershoot the connection
pressure.
■ When using longer hose lines,
consider the respective pressure
loss
■ Only use components that have
been tested and are suitable for
the respective purpose, such
as gas hose, pressure controller
and hose breakage protection
or leak gas protection
■ If possible, the length of the gas
hose should not exceed 2 m
■ Only pressure controllers with
a fixed outlet pressure setting
are permitted. The units may
only be operated out of the gas
phase
NOTE
This does not apply if the
correct condition is confirmed
by an expert.
NOTE
It is prohibited to exceed
or undershoot the required
connection pressure.
■ All common gas cylinder sizes
are permitted for the gas
supply. However, a gas cylinder
with at least 11 kg filling
weight is recommended. For
longer operation and nominal
heat outputs above 50 kW, it
is recommended that the gas
be drawn from several gas
cylinders in parallel. (Multi-
cylinder accessories set)
■ Only original spare parts may
be used for repairs
CAUTION
A constant unit connection
pressure of 1.5 bar (1500
mbar) must be guaranteed,

Assembly note
During the assembly or disassembly
of the gas hose, it is necessary
to counter-hold the unit by the
gas connection nipple with an
open-end wrench size 17, whilst
observing the left-handed thread.
This process also applies to the
pressure controller, hose breakage
protection and all further gas
components.
Tighten gas hose:
Turn the union nut anticlockwise
Loosen gas hose:
Turn the union nut clockwise
Icing up of gas cylinders
With insufficiently dimensioned
gas supply systems, there is a risk
of the pressurised gas cylinder
icing up.
Due to the reduction of the gas
pressure, it is no longer possible to
guarantee the correct gas supply
to the unit.
Crystalline frost formation on
the gas cylinder(s) must not be
defrosted with naked flames,
glowing objects, radiators, etc.
In order to avoid the gas
cylinder(s) icing up, it is necessary
to configure the gas supply
in accordance with the unit
connection value, the time in
operation and the ambient
temperature of the supply tank.

Troubleshooting diagnostics
After an unchangeable fault
shutdown, the red signal lamp
lights up. In this condition, it is
possible to press the unlock key
>3 seconds to activate the visual
troubleshooting diagnostics in
accordance with the fault code
table.
Pressing the unlock key again >3
seconds activates the interface
diagnostics. If interface diagnostics
is activated inadvertently, which
is apparent from the weak red
flickering light in the signal lamp,
pressing the unlock key once more
>3 seconds switches this off again.
The correct switching moment is
signalled by a yellow light pulse.
