Equipment details

The gas supply’s operating pressure (30 mbar)
must be the same as the unit’s operating
pressure (see type plate).
Liquid gas systems must comply with the
technical and administrative regulations of the
respective country of use (e.g. EN 1949 for
vehicles in Europe). The national legislation and
regulations (e.g. DVGW Work Sheet G 607 for
vehicles in Germany) must be observed.
In Germany, the gas system must be retested
every 2 years by a liquid gas specialist (DVFG,
TÜV, DEKRA). The test must be confirmed on
the respective test certificate (G 607).
The vehicle owner is always responsible for
arranging the inspection.
Liquid gas equipment may not be used when
refueling, 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. It is a good idea
to heat the device up several times in summer
operation (60 °C) and to make sure that the area
is well ventilated.
Heat-sensitive objects such as spray cans or
flammable liquids may not be stored in the
same compartment where the heater is installed
because, under certain conditions, this area may
be subject to elevated temperatures.
Only pressure regulating equipment that
complies with EN 12864 (in vehicles) with fixed
output pressure of 30 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.
For vehicles, we recommend Truma‘s
SecuMotion gas pressure regulator; for the two-
cylinder gas system we also recommend the
Truma DuoComfort changeover valve.
At temperatures of around 0 °C or less the gas
pressure regulator and the changeover valve
should be operated using the EisEx regulator
heater.
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
regularly for brittleness. Winter-proof special
hoses must always be used if the equipment is
operated during the winter.
Pressure regulating equipment and hoses
must be replaced with new ones no more
than 10 years after the date of manufacture
(every 8 years if used commercially). This is the
responsibility of the operator.
Important operating notes
If the cowl has been placed near or directly
beneath an opening window, the device must
be equipped with an automatic 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!
Always keep the cowl for the exhaust duct and
combustion air intake free of contamination
(slush, ice, leaves etc.).
The hot air outlets and the recirculated air
intake openings must be free so that the unit
does not overheat. The integrated temperature
limiter blocks the gas supply when the unit
becomes too hot.
Directive 2004/78/EC stipulates that a safety
shut-off device is required if motor homes are
being heated while driving.
The Truma SecuMotion gas pressure regulator
meets this requirement.
If no safety shut-off device is installed (e.g. the
Truma SecuMotion gas pressure regulator), the
gas cylinder must be closed while driving and
information signs must be attached to the gas
cylinder protection box and in the vicinity of the
control panel.
