General Instructions
◊
The unit may be operated only by those persons who
have been instructed regarding the unit’s operation
and the handling of liquid gas.
◊
When using the unit make sure always to ob-
serve the guiding principles of the countries and
states concerned.
◊
The unit may only be operated in rooms when
– the air rate fed to the unit is sufficient for combus-
tion and
– the rooms are well ventilated and de-ventilated
and
– the percentage of the substances which are injuri-
ous to health in the breathed in air has no inad-
missible concentration.
◊
A good and natural ventilation and deventilation
is given if e.g.
1. the room volume in m³ corresponds to at least 30
times the nominal heat load in kW of all the units
being operated in the room, and if a natural air ex-
change through doors and windows is ensured, or
2. if there are permanently open ventilation possibili-
ties for ingoing and outgoing air near the ceiling
and the floor, of which the size in m² corresponds
to at least 0.003 times the nominal heat load in
kW of all the units being operated in the room.
◊
A uniform unit connection pressure of 0.3 bar (300
mbar) of category
I
3B/P
is necessary for all countries
of the European Community.
◊
The connection pressure may not fall below or ex-
ceed the required value.
◊
When using longer hoses the corresponding pres-
sure loss has to be considered.
◊
Make sure to use exclusively components, such as
gas hose, pressure controller and tube security de-
vices (protection against breakage) or safety devices
against gas leakage, that have been tested and are
suitable for the intended purpose.
◊
The pressure controllers must have a firmly regu-
lated initial pressure of 300 mbar and are to be
equipped with a security device against tube break-
age.
◊
The unit may not be operated, if the gas occurs liq-
uid in to the burner.
◊
In building site operation it is only allowed to use
hoses which are suitable for liquid gas.
According to regional regulations.
◊
The length of the gas hose should not exceed 2 me-
tres.
◊
If there are special operational reasons and if corre-
sponding safety regulations are considered and the
length of the hoses are as short as possible it is also
possible to use longer hoses.
◊
Gas hoses are to be protected generally against
chemical, thermal and mechanical damage.
◊
In uncontrolled operation hoses with hose-break pro-
tection must be used.
◊
The operating personnel has to check the function of
operation and safety devices and the existence of
safety devices before starting the unit.
◊
If any defects are stated the superintending person
has to be informed.
◊
If any defect occurs which endangers the operating
security of the unit, the unit has to be switched off!
◊
The unit may be only maintained by trained persons
and only original spare parts may be used.
◊
Wearing and ageing parts of the unit have to be re-
placed regularly. This is not valid if an expert con-
firms the faultless function of the unit.
◊
If the unit has been switched off by the temperature
limiter due to overheating, the reason for the fault
has to be detected and eliminated.
For optimum unit operation, the device should not
be operated at an ambient temperature above 25 °C.
