If the burner makes an unusual noise or if the flame lifts off
while burning, it is likely that the regulator is faulty, and it is
essential to have it checked.
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 control equipment that complies with EN 12864
(in vehicles) with a fixed delivery pressure of 30 mbar must be
used for the gas system. The flow rate of the pressure control
device must correspond to at least the maximum consump-
tion 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.
Pressure regulating devices and hoses must be replaced with
new ones no more than 10 years after their date of manufac-
ture (every 8 years if used commercially). This is the responsi-
bility of the operator.
Important operating notes
1. The heat exchanger, the exhaust and combustion air
ducts and all connections must be checked by an expert
at regular intervals, and always after loud combustion
(misfiring).
The exhaust duct and the combustion air duct must
–
be firmly attached to the heater and the cowl without
leaks,
–
consist of one piece (not extended),
–
be routed without cross-section narrowing and rising
over their entire length,
–
be firmly attached with several clamps together with
the ÜR air duct.
No objects must be placed onto the exhaust and combustion
air ducts, since this could lead to damage.
Heaters with wrongly fitted or damaged exhaust
and combustion air ducts or damaged heat ex-
changers must not continue to be used!
2. Under no circumstances obstruct the upper hot air
outlet on the heater. Never hang clothes or washing or such
to dry directly in front of the heater or on it. Misusing the
heater in this way could seriously damage your heater though
overheating. Never put flammable objects near the heater!
Please observe this point for your own safety.
Attention: Due to the design, the heater front case will
become hot during operation. The operator is obliged
to ensure that due care is taken to protect third parties (small
children in particular).
3. Always observe the following when exhaust gas and
combustion air are routed through the side wall:
The cowls must be installed at the specified height (refer to
installation instructions). For duct lengths of 35 cm and longer,
you must install a double support DSW.
The lids to cover the cowls (accessories) must be attached
when the heater is not in use.
4. Always observe the following when exhaust gas is routed
via the roof:
If the caravan has a double skin, the exhaust gas cowl must
always pass through this as well. For this purpose use the
cowl leadthrough UEK (part no. 30630-04)!
If the heater keeps going out in extremely windy locations,
we recommend the use of an AKV cowl extension (part no.
30010-20800). This must be removed whilst the vehicle is in
motion so that it is not lost (risk of accident).
For winter camping and long-term camping we recommend
the SKV cowl extension kit (part no. 30690-00) that can be
screwed to the cowl section. This must be removed whilst the
vehicle is in motion so that it is not lost (risk of accident).
5. The combustion air intake under the vehicle floor must be
freed of dirt and slush. The intake opening of the heater is
therefore never to be in the spray area of the wheels, apply a
spray guard, if necessary.
Intended use
This heater is designed for installation in caravans and other
trailed vehicles. It is not approved for installation in boats.
Other forms of application are possible after previously
consulting Truma.
