2. Installation / Operation
The burner may only be installed by qualified
staff in accordance with the DVGW regula-
tions.
1. Insert and fix the gas lever supplied with
the burner into the screw thread hole on
the burner‘s operating element.
2. Check whether the type of gas and oper-
ating pressure required for the burner are
compatible with your gas supply.
3. Inspect the connection pipe to ensure it is
correctly fitted and in perfect condition.
4. Shut off the gas tap on the laboratory
bench.
5. Push the gas hose (DIN 30664) onto the
inlet nozzle of the
Bijou 90
right up to the
last groove. If necessary, secure the tube
with a clip or circular spring to prevent
it slipping off (see DVGW worksheet
G 621).
6. Adjust the
Bijou 90
gas lever to position
A and open the shutoff valve on the
laboratory bench. You should now clearly
hear gas flowing out. Carefully ignite the
burner from the side. Regulate the flame
as described in point 4. (Handling).
3. Areas of Caution
• The burner should not be used in areas
where there is a strong draught, as
this may cause the flame to be extin
-
guished unintentionally.
• Laboratory burners must only be used
under constant supervision. After
finishing work, the gas supply to the
burner must be shut off (shutoff valve;
disconnection from the gas main).
• When used in classrooms, laboratory
burners may only be put into operation
after first switching on the upstream
shutoff devices, such as central shut-
off for the entire room, group shutoff
device and shutoff valve.
• For installation and operation of gas
systems in labs and science lecture
rooms the regulations in the DVGW
Worksheet G621 (German regulations)
must be heeded.
• After use, the gas supply should be
shut off immediately via the shutoff
valve, or, by separating the gas con-
nection safety valve.
• If there is a strong smell of gas, close
the gas shutoff valve immediately and
take safety precautions
(see DVGW regulations).
• Always observe the accident preven-
tion regulations of the relevant employ-
er‘s liability insurers.
• Never use water or compressed air to
rinse or blow out burners! This could
flush out / blow out the sealant grease
causing the burner to leak.
