Trumatic E 2400 E
Natural gas heater with electronic control, built-in air distribu-
tion and thermostat

Safety instructions

If the gas system is leaking or if there is a smell of gas:
– extinguish all naked flames
– do not smoke
– switch off the appliances
– shut off the gas cylinder
– open windows and door
– do not actuate any electrical switches
– have the entire system checked by an expert!
Repairs may only be carried out by an expert!
A new O-ring must always be installed after dismantling the
exhaust duct!
Guarantee claims, warranty claims and acceptance of liability
will be ruled out in the event of the following:
– modifications to the unit (including accessories),
– modifications to the exhaust duct and the cowl,
– failure to use original Truma parts as replacement parts and
accessories,
– failure to follow the installation and operating instructions.
It also becomes illegal to use the appliance, and in some
countries this even makes it illegal to use the vehicle.
The gas supply's operating pressure (50 mbar) must be the
same as the unit's operating pressure (see type plate).
Natural gas heaters must be connected to the vehicles own
CNG system according the relevant technical and administra-
tive regulations applicable in the particular country of designa-
tion. In Germany, e.g. in accordance with DVGW Worksheet
G 609 Draft and VdTÜV Code of Practice 757. The Truma work
instruction "Natural Gas (CNG) Heaters in Motor Vehicles"
takes the relevant requirements into consideration.
For vehicles for commercial use, the relevant accident preven-
tion regulations issued by the professional associations are to
be respected (BGV D 34).
The testing of the low pressure gas supply for heating
and the equipment itself must be repeated in Germany by
an expert (DVFG, TÜV, DEKRA) in accordance with G 609
Draft within the same time periods as the main inspection
(§ 29 StVZO) and confirmed on an appropriate test certificate
(in Germany e.g. G 609 Draft, i.e. in the Truma test certificate).
The keeper of the vehicle is responsible for arranging
the inspection.
Pressure regulating equipment and hoses must be replaced
with new ones no more than 10 years after the date of manu-
facture (every 8 years if used commercially). This is the
responsibility of the operator.
Gas equipment must not be used when refuelling, in multi-
storey car parks, in garages or on ferries.
During the initial operation of a brand new appliance (or after
it has not been used for some time), a slight amount of fumes
and smell may be noticed for a short while. This can be rem-
edied by running the heater at maximum output and ensuring
adequate room ventilation.
If the burner makes an un-usual noise or if the flame lifts off, it
is likely that the regulator is faulty and it is essential to have it
checked.
Items sensitive to heat (e.g. spray cans) must not be stored
in the installation area, since excess temperatures may under
certain circumstances be incurred there.
Only pressure regulating equipment that is compliant with
EN 12864 or compliant with DIN 4811 in Germany (in vehi-
cles) with a fixed output pressure of 50 mbar may be used for
the gas system. The flow rate of the pressure control device
must correspond to at least the maximum consumption of all
devices installed by the system manufacturer.
Controller connecting hoses that meet national regulations
must always be used in the respective country for which the
equipment is destined. These hoses must be checked regu-
larly for brittleness. Winter-proof special hoses must always
be used if the equipment is operated during the winter.
If the pressure regulator is exposed to weather conditions
– especially on trucks – always make sure to protect the regu-
lator using the Truma protective cover (standard accessory in
truck attachment kit).

Important operating notes

If the chimney has been placed near or directly beneath an
opening window, the device must be equipped with an auto-
matic shut-off device in order to prevent operation with the
window open.
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 mounting of the appliance and the cowl.
Following a blow-back (misfire) always have the exhaust gas
system checked by an expert!
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.
Always keep the cowl for conducting exhaust gas and sup-
plying combustion air, free from contamination (slush, leaves
etc.).
The installed temperature limiter shuts off the gas supply if the
appliance becomes too hot. Therefore do not shut the warm
air outlets and the opening for the returning circulating air.
If the electronic control p.c.b. is defective, return it well
packed. If you fail to do so, guarantee claims shall no longer
be valid. Only use original p.c.b. as a spare part!
Always use original Truma parts for maintenance and repair
work!
For conducting the exhaust gas under the floor, the vehicle
floor must be sealed tight. There must also be three open
sides beneath the vehicle floor to ensure unhindered escape
of the exhaust gas (snow, aprons etc.).
