Switching on the
Heating
1. Remove cowl cap.
2. Turn on gas cylinder and
open quick-acting valve in the
gas supply line.
3. Adjust desired room tem-
perature at rotary knob.
4. Switching the heating on:
Control panel with sliding
switch:
Set the switch (a) to Heating
and switch (b) to the desired
output setting.
Control panel with rotary
switch:
Set the rotary switch to the
desired output setting (c).
If the outside temperature is
low, switch to high setting.
Note: The Trumatic E heater
has been tested and ap-
proved for operation, also
when the vehicle is moving.
The burner with fan assis-
tance guarantees satisfactory
operation, even under ex-
tremely windy conditions. It
may be necessary to observe
respective, country-specific
regulations for the operation
of liquid gas appliances when
the vehicle is moving.
Switching on the
Ventilation
Control panel with sliding
switch:
Set switch (a) to Ventilation
and switch (b) to the desired
output setting.
Control panel with rotary
switch:
Set the rotary switch to the
desired output setting (e).
Switching off
Set the sliding switch (a) or
the rotary switch (d) to the
centre. If the appliance is
switched off after a heating
phase, the fan can continue
running in order to make use
of the residual heat.
If the appliance is not used
for a prolonged period of
time, mount the cowl cap,
close quick-acting valve in
the gas supply line and turn
off gas cylinder.

Operating
instructions
Always observe the opera-
ting instructions and „Im-
portant operating notes“
prior to starting! The vehicle
owner is responsible for the
correct operation of the appli-
ance.
The installer or vehicle owner
must apply the yellow sticker
with the warning information,
which is enclosed with the
appliance, to a place in the
vehicle where it is clearly visi-
ble to all users (e.g. on the
wardrobe door)! Ask Truma to
send you stickers, if neces-
sary.

L.P.G. Heater with
electronic control,
built-in air distribution
and thermostat
lamp must be illuminated (the
fan is running). If the indicator
lamp is not illuminated, pos-
sibly check the (main) switch.
For this purpose observe re-
spective instructions of the
vehicle manufacturer.
During the heating operation,
while the flame is burning,
the green indicator lamp
lights up with twice the in-
tensity. This also makes it
possible to determine the in-
stantaneous switching point
of the room temperature.
Fuses
Fig. H4: The appliance fuse
(F1) is located on the elec-
tronic control PCB.
Important note: The fine-
wire fuse may only be re-
placed by a fuse of identical
design: 3.15 AT (slow-acting)
EN 60127-2-3.
Red indicator lamp
„Failure“
Should a failure occur, the red
indicator is illuminated per-
manently. Possible causes
for the failure can be e.g. no
gas, insufficient combustion
air, heavily soiled rotor, defec-
tive fuse etc.. Deactivate by
switching off and then
switching on again.
Flash operation indicates
that the operating voltage is
too low or too high for the
appliance (charge battery, if
necessary).
In event of faults, in Germany,
always contact the Truma
Service Centre, Tel.: (089)
4617-142. For other countries
please refer to the Interna-
tional Service (page 57).
Accessories
Fig. H6:
1. Control unit VG 2
- for heaters of driver's cabs
in tank vehicles, for the trans-
portation of hazardous goods
according to ADR (not to be
used in combination with a
time switch).
2. Outside switch AS
- for switching the heater on
and off from the outside of
the vehicle, e.g. for cargo
space heaters (available with
4 m or 10 m connecting ca-
bles).
3. Acoustic signalling
device ASM - gives an
acoustic signal in event of
a failure.
4. Time switch ZUE
- for pre-programming
3 switch-on times within
7 days, including 4 m con-
necting cable (suitable for
12 V and 24 V vehicle electri-
cal system).
5. Remote sensor FF
- monitors the room tempera-
ture independent of the posi-
tion of the control panel
(available with 4 m or 10 m
connecting cable).
6. Multiple connector MSD
- for connecting several ac-
cessories (e.g. time switch
and remote sensor).
Extension cable for acces-
sories - Items 1 - 6 of 4 m or
10 m (not illustrated).
7. Direct switch DIS
- for operating the heater at
high setting only, without
temperature control (available
with 4 m or 10 m connecting
cable). Replaces control pan-
el.
Or direct fixed temperature
switch DFS - for operating
the heater at a fixed tempera-
ture (40°C - 70°C depending
on the version). Replaces the
control panel.
All electrical accessories are
fitted with a connector and
can be connected individually.
Important
operating notes
1. In the event of the chimney
having been located in the
vicinity of a window (or a
hatch) which can be opened,
especially directly beneath it,
the window or hatch must re-
main closed during operation
(see warning plate).
2. The integrity and tight fit of
the exhaust gas double duct
must be checked regularly,
particularly at the end of long
trips. Also check the mount-
ing of the appliance and the
cowl.
3. Following a blow-back
(misfire) always have the ex-
haust gas system checked by
an expert!
4. If appliances are assembled
on the outside of the vehicle,
regularly check the flexible air
ducts for damage. A damaged
duct could lead to exhaust
gas entering the vehicle.
5. Always keep the cowl for
conducting exhaust gas and
supplying combustion air,
free from contamination
(slush, leaves etc.).
